Adding to my post above the Shepard of Hermas quote about the Tower,
"
CHAPTER XII
"First of all, sir," I said, "explain this to me: What is the meaning of the rock and the gate?" "This rock," he answered, "and this gate are the Son of God." "How, sir?" I said; "the rock is old, and the gate is new." "Listen," he said, "and understand, O ignorant man. The Son of God is older than all His creatures, so that He was a fellow-councillor with the Father in His work of creation: for this reason is He old." "And why is the gate new, sir?" I said. "Because," he answered, "He became manifest in the last days of the dispensation: for this reason the gate was made new, that they who are to be saved by it might enter into the kingdom of God. You saw," he said, "that those stones which came in through the gate were used for the building of the tower, and that those which did not come, were again thrown back to their own place? "I saw, sir," I replied. "In like manner," he continued, "no one shall enter into the kingdom of God unless he receive His holy name. For if you desire to enter into a city, and that city is surrounded by a wall, and has but one gate, can you enter into that city save through the gate which it has?" "Why, how can it be otherwise, sir?" I said. "If, then, you cannot enter into the city except through its gate, so, in like manner, a man cannot otherwise enter into the kingdom of God than by the name of His beloved Son. You saw," he added, "the multitude who were building the tower?" "I saw them, sir," I said. "Those," he said, "are all glorious angels, and by them accordingly is the Lord surrounded. And the gate is the Son of God. This is the one entrance to the Lord. In no other way, then, shall any one enter in to Him except through His Son. You saw," he continued, "the six men, and the tail and glorious man in the midst of them, who walked round the tower, and rejected the stones from the building? "I saw him, sir," I answered. "The glorious man," he said, "is the Son of God, and those six glorious angels are those who support Him on the right hand and on the left. None of these glorious angels," he continued, "will enter in unto God apart from Him.
Whosoever does not receive His name, shall not enter into the kingdom of God."
CHAPTER XIII
"And the tower," I asked, "what does it mean? "This tower," he replied, "is the Church." "And these virgins, who are they?" "They are holy spirits, and men cannot otherwise be found in the kingdom of God unless these have put their clothing upon them: for if you receive the name only, and do not receive from them the clothing, they are of no advantage to you. For these virgins are the powers of the Son of God. If you bear His name but possess not His power, it will be in vain that you bear His name. Those stones," he continued, "which you saw rejected bore His name, but did not put on the clothing of the virgins." "Of what nature is their clothing, sir?" I asked. "Their very names," he said, "are their clothing. Every one who bears the name of the Son of God, ought to bear the names also of these; for the Son Himself bears the names of these virgins. As many stones," he continued, "as you saw [come into the building of the tower through the hands ] of these virgins, and remaining, have been clothed with their strength. For this reason you see that the tower became of one stone with the rock. So also they who have believed on the Lord through His Son, and are clothed with these spirits, shall become one spirit, one body, and the colour of their garments shall be one. And the dwelling of such as bear the names of the virgins is in the tower." "Those stones, sir, that were rejected," I inquired, "on what account were they rejected? for they passed through the gate, and were placed by the hands of the virgins in the building of the tower." "Since you take an interest in everything," he replied, "and examine minutely, hear about the stones that were rejected. These all," he said, "received the name of God, and they received also the strength of these virgins. Having received, then, these spirits, they were made strong, and were with the servants of God; and theirs was one spirit, and one body, and one clothing. For they were of the same mind, and wrought righteousness. After a certain time, however, they were persuaded by the women whom you saw clothed in black, and having their shoulders exposed and their hair dishevelled, and beautiful in appearance. Having seen these women, they desired to have them, and clothed themselves with their strength, and put off the strength of the virgins. These, accordingly, were rejected from the house of God, and were given over to these women. But they who were not deceived by the beauty of these women remained in the house of God. You have," he said, "the explanation of those who were rejected."
CHAPTER XIV
"What, then, sir," I said, "if these men, being such as they are, repent and put away their desires after these women, and return again to the virgins, and walk in their strength and in their works, shall they not enter into the house of God? "They shall enter in," he said, "if they put away the works of these women, and put on again the strength of the virgins, and walk in their works. For on this account was there a cessation in the building, in order that, if these repent, they may depart into the building of the tower. But if they do not repent, then others will come in their place, and these at the end will be cast out. For all these things I gave thanks to the Lord, because He had pity on all that call upon His name; and sent the angel of repentance to us who sinned against Him, and renewed our spirit; and when we were already destroyed, and had no hope of life, He restored us to newness of life." "Now, sir," I continued,
"show me why the tower was not built upon the ground, but upon the rock and upon the gate." "Are you still," he said, "without sense and understanding? "I must, sir," I said, "ask you of all things, because I am wholly unable to understand them; for all these things are great and glorious, and difficult for man to understand." "Listen," he said: "the name of the Son of God is great, and cannot be contained, and supports the whole world. If, then, the whole creation is supported by the Son of God, what think ye of those who are called by Him, and bear the name of the Son of God, and walk in His commandments? do you see what kind of persons He supports? Those who bear His name with their whole heart. He Himself, accordingly, became a foundation to them, and supports them with joy, because they are not ashamed to bear His name."
CHAPTER XV.
"Explain to me, sir," I said, "the names of these virgins, and of those women who were clothed in black raiment." "Hear," he said, "the names of the stronger virgins who stood at the comers. The first is Faith, the second Continence, the third Power, the fourth Patience. And the others standing in the midst of these have the following names: Simplicity, Innocence, Purity, Cheerfulness, Truth, Understanding, Harmony, Love. He who bears these names and that of the Son of God will be able to enter into the kingdom of God. Hear, also," he continued, "the names of the women who had the
black garments; and of these four are stronger than the rest. The first is Unbelief, the second: Incontinence, the third Disobedience, the fourth Deceit. And their followers are called Sorrow, Wickedness, Wantonness, Anger, Falsehood, Folly, Backbiting, Hatred. The servant of God who bears these names shall see, indeed, the kingdom of God, but shall not enter into it." "And the stones, sir," I said, "which were taken out of the pit and fitted into the building: what are they?" "The first," he said, "the ten, viz, that were placed as a foundation, are the first generation, and the twenty-five the second generation, of righteous men; and the thirty-five are the prophets of God and His ministers; and the forty are the apostles and teachers of the preaching of the Son of God." "Why, then, sir," I asked, "did the virgins carry these stones also through the gate, and give them for the building of the tower?" "Because," he answered, "these were the first who bore these spirits, and they never departed from each other, neither the spirits from the men nor the men from the spirits, but the spirits remained with them until their falling asleep. And unless they had had these spirits with them, they would not have been of use for the building of this tower."
CHAPTER XVI
"Explain to me a little further, sir," I said. "What is it that you desire?" he asked. "Why, sir," I said, "did these stones ascend out of the pit, and be applied to the building of the tower, after having borne these spirits? "They were obliged," he answered, "to ascend through water in order that they might be made alive; for, unless they laid aside the deadness of their life, they could not in any other way enter into the
kingdom of God. Accordingly, those also who fell asleep received the seal of the Son of God. For," he continued, "before a man bears the name of the Son of God s he is dead; but when he receives the seal he lays aside his deadness, and obtains life. The seal, then, is the water: they descend into the water dead, and they arise alive. And to them, accordingly, was this seal preached, and they made use of it that they might enter into the kingdom of God." "Why, sir," I asked, "did the forty stones also ascend with them out of the pit, having already received the seal?" "Because," he said, "these apostles and teachers who preached the name of the Son of God, after falling asleep in the power and faith of the Son of God, preached it not only to those who were asleep, but themselves also gave them the seal of the preaching. Accordingly they descended with them into the water, and again ascended. [But these descended alive and rose up again alive; whereas they who had previously fallen asleep descended dead, but rose up again alive. ] By these, then, were they quickened and made to know the name of the Son of God. For this reason also did they ascend with them, and were fitted along with them into the building of the tower, and, untouched by the chisel, were built in along with them. For they slept in righteousness and in great purity, but only they had not this seal. You have accordingly the explanation of these also."
CHAPTER XVII
"I understand, sir," I replied. "Now, sir," I continued, "explain to me, with respect to the mountains, why their forms are various and diverse."
"Listen," he said: "these mountains are the twelve tribes, which inhabit the whole world. The Son of God, accordingly, was preached unto them by the apostles." "But why are the mountains of various kinds, some having one form, and others another? Explain that to me, sir." "Listen," he answered: "these twelve tribes that inhabit the whole world are twelve nations. And they vary in prudence and understanding. As numerous, then, as are the varieties of the mountains which you saw, are also the diversities of mind and understanding among these nations. And I will explain to you the actions of each one." "First, sir," I said, "explain this: why, when the mountains are so diverse, their stones, when placed in the building, became one colour, shining like those also that had ascended out of the pit." "Because," he said, "all the nations that dwell under heaven were called by hearing and believing upon the name of the Son of God. Having, therefore, received the seal, they had one understanding and one mind; and their faith became one, and their love one, and with the name they bore also the spirits of the virgins. On this account the building of the tower became of one colour, bright as the sun. But after they had entered into the same place, and became one body, certain of these defiled themselves, and were expelled from the race of the righteous, and became again what they were before, or rather worse."
CHAPTER XVIII
"How, sir," I said, "did they become worse, after having known God?" "He that does not know God," he answered, "and practises evil, receives a certain chastisement for his wickedness; but he that has known God, ought not any longer to do evil, but to do good. If, accordingly, when he ought to do good, he do evil, does not he appear to do greater evil than he who does not know God? For this reason, they who have not known God and do evil are condemned to death; but they who have known God, and have seen His mighty works, and still continue in evil, shall be chastised doubly, and shall die for ever.
In this way, then, will the Church of God be purified. For as you saw the stones rejected from the tower, and delivered to the evil spirits, and cast out thence, so [they also shall be cast out, and ] there shall be one body of the purified; as the tower also became, as it were, of one stone after its purification. In like manner also shall it be with the Church of God, after it has been purified, and has rejected the wicked, and the hypocrites, and the blasphemers, and the waverers, and those who commit wickedness of different kinds. After these have been cast away,
the Church of God shall be one body, of one mind, of one understanding, of one faith, of one love. And then the Son of God will be exceeding glad, and shall rejoice over them, because He has received His people pure." "All these things, sir," I said, "are great and glorious.
"Moreover, sir," I said, "explain to me the power and the actions of each one of the mountains, that every soul, trusting in the Lord, and hearing it, may glorify His great, and marvellous, and glorious name." "Hear," he said, "the diversity of the mountains and of the twelve nations.
CHAPTER XIX
"From the first mountain, which was black, they that believed are the following: apostates and blasphemers against the Lord, and betrayers of the servants of God. To these repentance is not open; but death lies before them, and on this account also are they black, for their race is a lawless one. And from the second mountain, which was bare, they who believed are the following: hypocrites, and teachers of wickedness. And these, accordingly, are like the former, not having any fruits of righteousness; for as their mountain was destitute of fruit, so also such men have a name indeed, but are empty of faith, and there is no fruit of truth in them. They indeed have repentance in their power, if they repent quickly; but if they are slow in so doing, they shall die along with the former." "Why, sir," I said, "have these repentance, but the former not? for their actions are nearly the same." "On this account,"
he said, "have these repentance, because they did not blaspheme their Lord, nor become betrayers of the servants of God; but on account of their desire of possessions they became hypocritical, and each one taught according to the desires of men that were sinners. But they will suffer a certain punishment; and repentance is before them, because they were not blasphemers or traitors.
