The thread is about ten commandments not about the Sabbath command alone.
CCT 2168
The Jewish Sabbath Changed To Sunday By The Apostles
CCT 2169 The Apostles therefore resolved to consecrate the first day of the week to the divine worship, and called it the Lord's day. St. John in the Apocalypse makes mention of the Lord's day; and the Apostle commands collections to be made on the first day of the week, that is, according to the interpretation of St. Chrysostom, on the Lord's day. From all this we learn that even then the Lord's day was kept holy in the Church.
CCT 2170 Four Parts Of This Commandment
CCT 2171 In order that the faithful may know what they are to do and what to avoid on the Lord's day, it will not be foreign to his purpose, if the pastor, dividing the Commandment into its four natural parts, explain each word of it carefully.
CCT 2172 First Part of this Commandment
CCT 2173 In the first place, then, he should explain generally the meaning of these words: Remember that thou keep holy the sabbath day.
CCT 2174 "Remember"
CCT 2175 The word remember is appropriately made use of at the beginning of the Commandment to signify that the sanctification of that particular day belonged to the ceremonial law. Of this it would seem to have been necessary to remind the people; for, although the law of nature commands us to devote a certain portion of time to the external worship to God, it fixes no particular day for the performance of this duty.
CCT 2176 They are also to be taught, that from these words we may learn how we should employ our time during the week; that we are to keep constantly in view the Lord's day, on which we are, as it were, to render an account to God for our occupations and conduct; and that therefore our works should be such as not to be unacceptable in the sight of God, or, as it is written, be to us an occasion of grief, and a scruple of heart.
CCT 2177 Finally, we are taught, and the instruction demands our serious attention, that there will not be wanting occasions which may lead to a forgetfulness of this Commandment, such as the evil example of others who neglect its observance, and an inordinate love of amusements and sports, which frequently withdraw from the holy and religious observance of the Lord's day.
CCT 2178 Sabbath
CCT 2179 We now come to the meaning of the word sabbath. Sabbath is a Hebrew word which signifies cessation. To keep the Sabbath, therefore, means to cease from labour and to rest. In this sense the seventh day was called the Sabbath, because God, having finished the creation of the world, rested on that day from all the work which He had done. Thus it is called by the Lord in Exodus.
CCT 2180 Later on, not only the seventh day, but, in honour of that day, the entire week was called by the same name; and in this meaning of the word, the Pharisee says in St. Luke: I fast twice in a sabbath. So much will suffice with regard to the signification of the word sabbath.
CCT 2181 "Keep Holy"
CCT 2182 In the Scriptures keeping holy the Sabbath means a cessation from bodily labour and from business, as is clear from the following words of the Commandment: Thou shalt do no work on it. But this is not all that it means; otherwise it would have been sufficient to say in Deuteronomy, Observe the day of the sabbath; but it is added, and sanctify it; and these additional words prove that the Sabbath is a day sacred to religion, set apart for works of piety and devotion.
CCT 2183 We sanctify the Sabbath fully and perfectly, therefore, when we offer to God works of piety and religion. This is evidently the Sabbath, which Isaias calls delightful; for festivals are, as it were, the delight of God and of pious men. And if to this religious and holy observance of the Sabbath we add works of mercy, the rewards promised us in the same chapter are numerous and most important.
CCT 2184 The true and proper meaning, therefore, of this Commandment tends to this, that we take special care to set apart some fixed time, when, disengaged from bodily labour and worldly affairs, we may devote our whole being, soul and body, to the religious veneration of God.
CCT 2185 Second Part of this Commandment
CCT 2186 The second part of the precept declares that the seventh day was consecrated by God to His worship; for it is written: Six days shalt thou labour, and do all thy works; but on the seventh day is the sabbath of the Lord thy God. From these words we learn that the Sabbath is consecrated to the Lord, that we are required on that day to render Him the duties of religion, and to know that the seventh day is a sign of the Lord's rest.
CCT 2187 "The Seventh Day Is The Sabbath Of The Lord Thy God"
CCT 2188 This particular day was fixed for the worship of God, because it would not have been well to leave to a rude people the choice of a time of worship, lest, perhaps, they might have imitated the festivals of the Egyptians.
CCT 2189 The last day of the week was, therefore, chosen for the worship of God, and in this there is much that is symbolic. Hence in Exodus,' and in Ezechiel the Lord calls it a sign: See that you keep my sabbath because it is a sign between me and you in your generation, that you may know that I am the Lord who sanctify you.
CCT 2190 It was a sign that man should dedicate and sanctify himself to God, since even the very day is devoted to Him. For the holiness of the day consists in this, that on it men are bound in a special manner to practise holiness and religion.
CCT 2191 It was also a sign, and, as it were, a memorial of the stupendous work of the creation. Furthermore, to the Jews it was a traditional sign, reminding them that they had been delivered by the help of God from the galling yoke of Egyptian bondage. This the Lord Himself declares in these words: Remember that thou also didst serve in Egypt, and the Lord thy God brought thee out from thence with a strong hand and a stretched out arm. Therefore hath he commanded thee that thou shouldst observe the sabbath day.
CCT 2192 It is also a sign of a spiritual and celestial sabbath. The spiritual sabbath consists in a holy and mystical rest, wherein the old man being buried with Christ, is renewed to life and carefully applies himself to act in accordance with the spirit of Christian piety. For those who were once darkness but are now light in the Lord, should walk as children of the light, in all goodness and justice and truth, having no fellowship with the unfruitful works of darkness.
CCT 2193 The celestial sabbath, as St. Cyril observes on these words of the Apostle, There remaineth therefore a day of rest for the people of God, is that life in which, living with Christ, we shall enjoy all good, when sin shall be eradicated, according to the words: No lion shall be there, nor shall any mischievous beast go up by it, nor be found there; but a path shall be there, and it shall be called the holy way; for in the vision of God the souls of the Saints obtain every good. The pastor therefore should exhort and animate the faithful in the words: Let us hasten therefore to enter into that rest.
