The temple had an outer court for the Gentiles. The synagogues did not. Synagogues were for Jews, converts to Judaism, and people studying to become converts to Judaism.
The historical record of the early church states that the Christians worshiped God on Sunday, not on the Saturday Sabbath. The Sabbath was mandated by Moses for the Jews and the converts to Judaism. The Sabbath was not ever commanded for the Gentile Christians.
The Didache
1. But every Lord’s day do ye gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure. (Didache Chapter XIV.11 —Christian Assembly on the Lord’s Day. 14 [A.D. 70]).
The Letter of Barnabas
Since, therefore, the days are evil, and Satan possesses the power of this world, we ought to give heed to ourselves, and diligently inquire into the ordinances of the Lord. Fear and patience, then, are helpers of our faith; and long-suffering and continence are things which fight on our side. While these remain pure in what respects the Lord, Wisdom, Understanding, Science, and Knowledge rejoice along with them. For He hath revealed to us by all the prophets that He needs neither sacrifices, nor burnt-offerings, nor oblations, saying thus, “What is the multitude of your sacrifices unto Me, saith the Lord? I am full of burnt-offerings, and desire not the fat of lambs, and the blood of bulls and goats, not when ye come to appear before Me: for who hath required these things at your hands? Tread no more My courts, not though ye bring with you fine flour. Incense is a vain abomination unto Me, and your new moons and sabbaths I cannot endure.” He has therefore abolished these things, that the new law of our Lord Jesus Christ, which is without the yoke of necessity, might have a human oblation (The Epistle of Barnabas 1 Chapter II.—The Jewish sacrifices are now abolished.)
Further, He says to them, “Your new moons and your Sabbath I cannot endure.” Ye perceive how He speaks: Your present Sabbaths are not acceptable to Me, but that is which I have made, [namely this,] when, giving rest to all things, I shall make a beginning of the eighth day, that is, a beginning of another world. Wherefore, also, we keep the eighth day with joyfulness, the day also on which Jesus rose again from the dead. And when He had manifested Himself, He ascended into the heavens. (The Epistle of Barnabas Chapter XV.—The false and the true Sabbath. [A.D. 74]).
Ignatius of Antioch
If, therefore, those who were brought up in the ancient order of things have come to the possession of a new hope, no longer observing the Sabbath, but living in the observance of the Lord’s Day, on which also our life has sprung up again by Him and by His death—whom some deny, by which mystery we have obtained faith, and therefore endure, that we may be found the disciples of Jesus Christ, our only Master (Letter to the Magnesians (shorter) Chapter IX.—Let us live with Christ [A.D. 110]).
During the Sabbath He continued under the earth in the tomb in which Joseph of Arimathæa had laid Him. At the dawning of the Lord’s day He arose from the dead, according to what was spoken by Himself, “As Jonah was three days and three nights in the whale’s belly, so shall the Son of man also be three days and three nights in the heart of the earth.” The day of the preparation, then, comprises the passion; the Sabbath embraces the burial; the Lord’s Day contains the resurrection (The Epistle of Ignatius to the Trallians Longer Versions. Chapter IX.—Reference to the history of Christ.)
Justin Martyr
The Lawgiver is present, yet you do not see Him; to the poor the Gospel is preached, the blind see, yet you do not understand. You have now need of a second circumcision, though you glory greatly in the flesh. The new law requires you to keep perpetual sabbath, and you, because you are idle for one day, suppose you are pious, not discerning why this has been commanded you: and if you eat unleavened bread, you say the will of God has been fulfilled. The Lord our God does not take pleasure in such observances: if there is any perjured person or a thief among you, let him cease to be so; if any adulterer, let him repent; then he has kept the sweet and true sabbaths of God. If any one has impure hands, let him wash and be pure. (Dialogue with Trypho the Jew Chapter XII.—The Jews violate the eternal law, and interpret ill that of Moses.)
For we too would observe the fleshly circumcision, and the Sabbaths, and in short all the feasts, if we did not know for what reason they were enjoined you,—namely, on account of your transgressions and the hardness of your hearts. For if we patiently endure all things contrived against us by wicked men and demons, so that even amid cruelties unutterable, death and torments, we pray for mercy to those who inflict such things upon us, and do not wish to give the least retort to any one, even as the new Lawgiver commanded us: how is it, Trypho, that we would not observe those rites which do not harm us, —I speak of fleshly circumcision, and Sabbaths, and feasts? (Dialogue with Trypho the Jew Chapter XVIII.—Christians would observe the law, if they did not know why it was instituted. [A.D. 155]).
And we afterwards continually remind each other of these things. And the wealthy among us help the needy; and we always keep together; and for all things wherewith we are supplied, we bless the Maker of all through His Son Jesus Christ, and through the Holy Ghost. And on the day called Sunday,1 all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability, and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given, and to those who are absent a portion is sent by the deacons. And they who are well to do, and willing, give what each thinks fit; and what is collected is deposited with the president, who succours the orphans and widows and those who, through sickness or any other cause, are in want, and those who are in bonds and the strangers sojourning among us, and in a word takes care of all who are in need. But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, having wrought a change in the darkness and matter, made the world; and Jesus Christ our Saviour on the same day rose from the dead. For He was crucified on the day before that of Saturn (Saturday); and on the day after that of Saturn, which is the day of the Sun, having appeared to His apostles and disciples, He taught them these things, which we have submitted to you also for your consideration. (First Apology Chapter LXVII.—Weekly worship of the Christians. [A.D. 155]).
“Wherefore, Trypho, I will proclaim to you, and to those who wish to become proselytes, the divine message which I heard from that man. Do you see that the elements are not idle, and keep no Sabbaths? Remain as you were born. For if there was no need of circumcision before Abraham, or of the observance of Sabbaths, of feasts and sacrifices, before Moses; no more need is there of them now, after that, according to the will of God, Jesus Christ the Son of God has been born without sin, of a virgin sprung from the stock of Abraham. For when Abraham himself was in uncircumcision, he was justified and blessed by reason of the faith which he reposed in God, as the Scripture tells. Moreover, the Scriptures and the facts themselves compel us to admit that He received circumcision for a sign, and not for righteousness. (The Second Apology of Justin for the Christians Addressed to the Roman Senate. Chapter XXIII.—The opinion of the Jews regarding the law does an injury to God.)
“As, then, circumcision began with Abraham, and the Sabbath and sacrifices and offerings and feasts with Moses, and it has been proved they were enjoined on account of the hardness of your people’s heart, so it was necessary, in accordance with the Father’s will, that they should have an end in Him who was born of a virgin, of the family of Abraham and tribe of Judah, and of David; in Christ the Son of God, who was proclaimed as about to come to all the world, to be the everlasting law and the everlasting covenant, even as the forementioned prophecies show. (The Second Apology of Justin for the Christians Addressed to the Roman Senate. Chapter XLIII.—He concludes that the law had an end in Christ, who was born of the Virgin.)
Tertullian
“[L]et him who contends that the Sabbath is still to be observed as a balm of salvation, and circumcision on the eighth day . . . teach us that, for the time past, righteous men kept the Sabbath or practiced circumcision, and were thus rendered ‘friends of God.’ For if circumcision purges a man, since God made Adam uncircumcised, why did he not circumcise him, even after his sinning, if circumcision purges? . . . Therefore, since God originated Adam uncircumcised and unobservant of the Sabbath, consequently his offspring also, Abel, offering him sacrifices, uncircumcised and unobservant of the Sabbath, was by him [God] commended [
Gen. 4:1–7,
Heb. 11:4]. . . . Noah also, uncircumcised—yes, and unobservant of the Sabbath—God freed from the deluge. For Enoch too, most righteous man, uncircumcised and unobservant of the Sabbath, he translated from this world, who did not first taste death in order that, being a candidate for eternal life, he might show us that we also may, without the burden of the law of Moses, please God” (An Answer to the Jews Chapter II.—The Law Anterior to Moses. [A.D. 203]).
It follows, accordingly, that, in so far as the abolition of carnal circumcision and of the old law is demonstrated as having been consummated at its specific times, so also the observance of the Sabbath is demonstrated to have been temporary.For the Jews say, that from the beginning God sanctified the seventh day, by resting on it from all His works which He made; and that thence it was, likewise, that Moses said to the People: “Remember the day of the sabbaths, to sanctify it: every servile work ye shall not do therein, except what pertaineth unto life.” Whence we (Christians) understand that we still more ought to observe a sabbath from all “servile work” always, and not only every seventh day, but through all time. And through this arises the question for us, what sabbath God willed us to keep? For the Scriptures point to a sabbath eternal and a sabbath temporal. For Isaiah the prophet says, “Your sabbaths my soul hateth;” and in another place he says, “My sabbaths ye have profaned.”9 Whence we discern that the temporal sabbath is human, and the eternal sabbath is accounted divine; concerning which He predicts through Isaiah: “And there shall be,” He says, “month after month, and day after day, and sabbath after sabbath; and all flesh shall come to adore in Jerusalem, saith the Lord;” which we understand to have been fulfilled in the times of Christ, when “all flesh”—that is, every nation—“came to adore in Jerusalem” God the Father, through Jesus Christ His Son, as was predicted through the prophet: “Behold, proselytes through me shall go unto Thee.” Thus, therefore, before this temporal sabbath, there was withal an eternal sabbath foreshown and foretold; just as before the carnal circumcision there was withal a spiritual circumcision foreshown. In short, let them teach us, as we have already premised, that Adam observed the sabbath; or that Abel, when offering to God a holy victim, pleased Him by a religious reverence for the sabbath; or that Enoch, when translated, had been a keeper of the sabbath; or that Noah the ark-builder observed, on account of the deluge, an immense sabbath; or that Abraham, in observance of the sabbath, offered Isaac his son; or that Melchizedek in his priesthood received the law of the sabbath
But the Jews are sure to say, that ever since this precept was given through Moses, the observance has been binding. Manifest accordingly it is, that the precept was not eternal nor spiritual, but temporary, which would one day cease. In short, so true is it that it is not in the exemption from work of the sabbath—that is, of the seventh day—that the celebration of this solemnity is to consist, that Joshua the son of Nun, at the time that he was reducing the city Jericho by war, stated that he had received from God a precept to order the People that priests should carry the ark of the testament of God seven days, making the circuit of the city; and thus, when the seventh day’s circuit had been performed, the walls of the city would spontaneously fall. Which was so done; and when the space of the seventh day was finished, just as was predicted, down fell the walls of the city. Whence it is manifestly shown, that in the number of the seven days there intervened a sabbath-day. For seven days, whencesoever they may have commenced, must necessarily include within them a sabbath-day; on which day not only must the priests have worked, but the city must have been made a prey by the edge of the sword by all the people of Israel. Nor is it doubtful that they “wrought servile work,” when, in obedience to God’s precept, they drave the preys of war. For in the times of the Maccabees, too, they did bravely in fighting on the sabbaths, and routed their foreign foes, and recalled the law of their fathers to the primitive style of life by fighting on the sabbaths. Nor should I think it was any other law which they thus vindicated, than the one in which they remembered the existence of the prescript touching “the day of the sabbaths.” Whence it is manifest that the force of such precepts was temporary, and respected the necessity of present circumstances; and that it was not with a view to its observance in perpetuity that God formerly gave them such a law. (An Answer to the Jews Chapter IV.—Of the Observance of the Sabbath.)
Therefore, since it is manifest that a sabbath temporal was shown, and a sabbath eternal foretold; a circumcision carnal foretold, and a circumcision spiritual pre-indicated; a law temporal and a law eternal formally declared; sacrifices carnal and sacrifices spiritual foreshown; it follows that, after all these precepts had been given carnally, in time preceding, to the people Israel, there was to supervene a time whereat the precepts of the ancient Law and of the old ceremonies would cease, and the promise3 of the new law, and the recognition of spiritual sacrifices, and the promise of the New Testament, supervene;4 while the light from on high would beam upon us who were sitting in darkness, and were being detained in the shadow of death.5 And so there is incumbent on us a necessity6 binding us, since we have premised that a new law was predicted by the prophets, and that not such as had been already given to their fathers at the time when He led them forth from the land of Egypt,7 to show and prove, on the one hand, that that old Law has ceased, and on the other, that the promised new law is now in operation.
And, indeed, first we must inquire whether there be expected a giver of the new law, and an heir of the new testament, and a priest of the new sacrifices, and a purger of the new circumcision, and an observer of the eternal sabbath, to suppress the old law, and institute the new testament, and offer the new sacrifices, and repress the ancient ceremonies, and suppress8 the old circumcision together with its own sabbath, and announce the new kingdom which is not corruptible. Inquire, I say, we must, whether this giver of the new law, observer of the spiritual sabbath, priest of the eternal sacrifices, eternal ruler of the eternal kingdom, be come or no: that, if he is already come, service may have to be rendered him; if he is not yet come, he may have to be awaited, until by his advent it be manifest that the old Law’s precepts are suppressed, and that the beginnings of the new law ought to arise. And, primarily, we must lay it down that the ancient Law and the prophets could not have ceased, unless He were come who was constantly announced, through the same Law and through the same prophets, as to come. (An Answer to the Jews Chapter VI.—Of the Abolition and the Abolisher of the Old Law. [A.D. 203]).
But you, many of you, also under pretence sometimes of worshipping the heavenly bodies, move your lips in the direction of the sunrise. In the same way, if we devote Sun-day to rejoicing, from a far different reason than Sun-worship, we have some resemblance to those of you who devote the day of Saturn to ease and luxury, though they too go far away from Jewish ways, of which indeed they are ignorant. (Apology Chapter XVI.)
Constitutions of the holy apostles
But from the even of the fifth day till [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]-crowing break your fast when it is daybreak of the first day of the week, which is the Lord’s day. (Book V. Sec. III.—On Feast Days and Fast Days – Concerning the Watching All the Night of the Great Sabbath, and Concerning the Day of the Resurrection. XIX)
But assemble yourselves together every day, morning and evening, singing psalms and praying in the Lord’s house: in the morning saying the sixty-second Psalm, and in the evening the hundred and fortieth, but principally on the Sabbath-day. And on the day of our Lord’s resurrection, which is the Lord’s day, meet more diligently, sending praise to God that made the universe by Jesus, and sent Him to us, and condescended to let Him suffer, and raised Him from the dead. (Book II. Sec. VII.—On Assembling in the Church. That Every Christian Ought to Frequent the Church Diligently Both Morning and Evening LIX ).
Origen
If it be objected to us on this subject that we ourselves are accustomed to observe certain days, as for example the Lord’s day, the Preparation, the Passover, or Pentecost, I have to answer, that to the perfect Christian, who is ever in his thoughts, words, and deeds serving his natural Lord, God the Word, all his days are the Lord’s, and he is always keeping the Lord’s day. (Origen Against Celsus. Book 8 Chapter XXII.)
Peter, Archbishop of Alexandria
No one shall find fault with us for observing the fourth day of the week, and the preparation, on which it is reasonably enjoined us to fast according to the tradition. On the fourth day, indeed, because on it the Jews took counsel for the betrayal of the Lord; and on the sixth, because on it He himself suffered for us. But the Lord’s day we celebrate as a day of joy, because on it He rose again, on which day we have received it for a custom not even to bow the knee. (The Canonical Epistle Canon XV.)
Cyprian
For because the eighth day, that is, the first day after the Sabbath, was to be that on which the Lord should rise again, and should quicken us, and give us circumcision of the spirit, the eighth day, that is, the first day after the Sabbath, and the Lord’s day, went before in the figure; which figure ceased when by and by the truth came, and spiritual circumcision was given to us. (Epistle LVIII.2 To Fidus, on the Baptism of Infants. 4)
Victorinus
“The sixth day [Friday] is called parasceve, that is to say, the preparation of the kingdom. . . . On this day also, on account of the passion of the Lord Jesus Christ, we make either a station to God or a fast. On the seventh day he rested from all his works, and blessed it, and sanctified it. On the former day we are accustomed to fast rigorously, that on the Lord’s day we may go forth to our bread with giving of thanks. And let the parasceve become a rigorous fast, lest we should appear to observe any Sabbath with the Jews . . . which Sabbath he [Christ] in his body abolished” (The Creation of the World [A.D. 300]).
This sixth day is called parasceve,5 that is to say, the preparation of the kingdom. For He perfected Adam, whom He made after His image and likeness. But for this reason He completed His works before He created angels and fashioned man, lest perchance they should falsely assert that they had been His helpers. On this day also, on account of the passion of the Lord Jesus Christ, we make either a station to God, or a fast. On the seventh day He rested from all His works, and blessed it, and sanctified it. On the former day we are accustomed to fast rigorously, that on the Lord’s day we may go forth to our bread with giving of thanks. And let the parasceve become a rigorous fast, lest we should appear to observe any Sabbath with the Jews, which Christ Himself, the Lord of the Sabbath, says by His prophets that “His soul hateth;”1 which Sabbath He in His body abolished, although, nevertheless, He had formerly Himself commanded Moses that circumcision should not pass over the eighth day, which day very frequently happens on the Sabbath, as we read written in the Gospel. (On the Creation of the World p4 )
Eusebius of Caesarea
“They [the early saints of the Old Testament] did not care about circumcision of the body, neither do we [Christians]. They did not care about observing Sabbaths, nor do we. They did not avoid certain kinds of food, neither did they regard the other distinctions which Moses first delivered to their posterity to be observed as symbols; nor do Christians of the present day do such things” (Church History 1:4:8 [A.D. 312]).
“[T]he day of his [Christ’s] light . . . was the day of his resurrection from the dead, which they say, as being the one and only truly holy day and the Lord’s day, is better than any number of days as we ordinarily understand them, and better than the days set apart by the Mosaic law for feasts, new moons, and Sabbaths, which the apostle [Paul] teaches are the shadow of days and not days in reality” (Proof of the Gospel 4:16:186 [A.D. 319]).
“For as the name Christians is intended to indicate this very idea, that a man, by the knowledge and doctrine of Christ, is distinguished by modesty and justice, by patience and a virtuous fortitude, and by a profession of piety towards the one and only true and supreme God; all this no less studiously cultivated by them than by us. They did not, therefore, regard circumcision, nor observe the Sabbath, neither do we; neither do we abstain from certain foods, nor regard other injunctions, which Moses subsequently delivered to be observed in types and symbols, because such things as these do not belong to Christians.” (Eusebius Ecclesiastical History, Book 1, Chapter 5 (c. 315 A.D.)
“The Ebionites cherished low and mean opinions of Christ. For they considered Him a plain and common man, and justified only by His advances in virtue, and that He was born of the Virgin Mary, by natural generation. With them the observance of the law was altogether necessary, as if they could not be saved, only by faith in Christ and a corresponding life. These, indeed, thought on the one hand that all of the epistles of the apostles ought to be rejected, calling him an apostate from the law, but on the other, only using the gospel according to the Hebrews, they esteem the others as of little value. They also observe the Sabbath and other disciplines of the Jews, just like them, but on the other hand, they also celebrate the Lord’s days very much like us, in commemoration of His resurrection.” (Eusebius Ecclesiastical History, Book 3, Chapter 27 (c. 315 A.D.)
5. The Sabbath and the rest of the discipline of the Jews they observed just like them, but at the same time, like us, they celebrated the Lord’s days as a memorial of the resurrection of the Saviour.
6. Wherefore, in consequence of such a course they received the name of Ebionites, which signified the poverty of their understanding. For this is the name by which a poor man is called among the Hebrews. (Book III. Chapter XXVII.—The Heresy of the Ebionites 5 & 6)
Council of Laodicea
Christians must not judaize by resting on the Sabbath, but must work on that day, rather honouring the Lord’s Day; and, if they can, resting then as Christians. But if any shall be found to be judaizers, let them be anathema from Christ. (Canon Canon XXIX. [A.D. 360]).
John Chrysostom
For though few are now circumcised, yet, by fasting and observing the sabbath with the Jews, they equally exclude themselves from grace. If Christ avails not to those who are only circumcised, much more is peril to be feared where fasting and sabbatizing are observed, and thus two commandments of the Law are kept in the place of one. And this is aggravated by a consideration of time: for they so acted at first while the city and temple and other institutions yet existed; but these who with the punishment of the Jews, and the destruction of the city before their eyes,1 observe more precepts of the Law than the others did, what apology can they find for such observance, at the very time when the Jews themselves, in spite of their strong desire, cannot keep it? Thou hast put on Christ, thou hast become a member of the Lord, and been enrolled in the heavenly city, and dost thou still grovel in the Law? How is it possible for thee to obtain the kingdom? Listen to Paul’s words, that the observance of the Law overthrows the Gospel, and learn, if thou wilt, how this comes to pass, and tremble, and shun this pitfall. Wherefore dost thou keep the sabbath, and fast with the Jews? Is it that thou fearest the Law and abandonment of its letter? But thou wouldest not entertain this fear, didst thou not disparage faith as weak, and by itself powerless to save. A fear to omit the sabbath plainly shows that you fear the Law as still in force; and if the Law is needful, it is so as a whole, not in part, nor in one commandment only; and if as a whole, the righteousness which is by faith is little by little shut out. If thou keep the sabbath, why not also be circumcised? and if circumcised, why not also offer sacrifices? If the Law is to be observed, it must be observed as a whole, or not at all.” (Homilies on
Galatians 2:17 [A.D. 395]).
Augustine of Hippo
Well, then, is it owing to the one precept about the Sabbath-day, which is included in it, that the Decalogue is called “the letter that killeth?” Because, forsooth, every man that still observes that day in its literal appointment is carnally wise, but to be carnally wise is nothing else than death? And must the other nine commandments, which are rightly observed in their literal form, not be regarded as belonging to the law of works by which none is justified, but to the law of faith whereby the just man lives? Who can possibly entertain so absurd an opinion as to suppose that “the ministration of death, written and engraven in stones,” is not said equally of all the ten commandments, but only of the solitary one touching the Sabbath-day? (The Spirit and the Chapter 24 The Passage in Corinthians).
So he says elsewhere, “Let no man judge you in meat, or in drink, or in respect of an holy day, or of the new moon or of the sabbath-days, which are a shadow of things to come.” Here also, when he says, “Let no one judge you” in these things, he shows that we are no longer bound to observe them. And when he says, “which are a shadow of things to come,” he explains how these observances were binding at the time when the things fully disclosed to us were symbolized by these shadows of future things. (Reply to Faustus the Manichæan. Book VI-2)
He brought it about that His body rested from all its works on Sabbath in the tomb, and that His resurrection on the third day, which we call the Lord’s day, the day after the Sabbath, and therefore the eighth, proved the circumcision of the eighth day to be also prophetical of Him. (Reply to Faustus the Manichæan. Book XVI.-29)
So, when you ask why a Christian does not keep the Sabbath, if Christ came not to destroy the law, but to fulfill it, my reply is, that a Christian does not keep the Sabbath precisely because what was prefigured in the Sabbath is fulfilled in Christ. For we have our Sabbath in Him who said, “Come unto me, all ye that labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart, and ye shall find rest unto your souls.” (Reply to Faustus the Manichæan. Book XIX.-9)
And by this I am persuaded that exemption from fasting on the seventh day is more suitable, not indeed to obtain, but to foreshadow, that eternal rest in which the true Sabbath is realized, and which is obtained only by faith, and by that righteousness whereby the daughter of the King is all glorious within., (Letters of Augustine Letter XXXVI. Chapter 6. 25)
Wherefore, although the sacramental import of the 8th number, as signifying the resurrection, was by no means concealed from the holy men of old who were filled with the spirit of prophecy (for in the title of Psalms [vi. and xii.] we find the words “for the eighth,” and infants were circumcised on the eighth day; and in Ecclesiastes it is said, with allusion to the two covenants, “Give a portion to seven, and also to eight” ); nevertheless before the resurrection of the Lord, it was reserved and hidden, and the Sabbath alone was appointed to be observed, because before that event there was indeed the repose of the dead (of which the Sabbath rest was a type), but there was not any instance of the resurrection of one who, rising from the dead, was no more to die, and over whom death should no longer have dominion; this being done in order that, from the time when such a resurrection did take place in the Lord’s own body (the Head of the Church being the first to experience that which His body, the Church, expects at the end of time), the day upon which He rose, the eighth day namely (which is the same with the first of the week), should begin to be observed as the Lord’s day. The same reason enables us to understand why, in regard to the day of keeping the passover, on which the Jews were commanded to kill and eat a lamb, which was most clearly a foreshadowing of the Lord’s Passion, there was no injunction given to them that they should take the day of the week into account, waiting until the Sabbath was past, and making the beginning of the third week of the moon coincide with the beginning of the third week of the first month; the reason being, that the Lord might rather in His own Passion declare the significance of that day, as He had come also to declare the mystery of the day now known as the Lord’s day, the eighth namely, which is also the first of the week. (Letter LV. Or Book II. of Replies to Questions of Januarius.(a.d. 400.). Chapter 8. 23)
