“The vision which I saw, my brethren, was of the following nature . . . [An] old woman approached, accompanied by six young men . . . [And] she said to me . . . ‘Lo! do you not see opposite to you a great tower, built upon the waters, of splendid square stones?’ For the tower was built square by the six young men who had come with her. But myriads of men were carrying stones to it, some dragging them from the depths, others removing them from the land, and they handed them to these six young men. . . . [And the woman said:] ‘The tower which you see building is myself, the Church . . . the tower is built upon the waters . . . because your life has been and will be “saved through water” [1 Pet. 3:20–21] . . . the six young men . . . are the holy angels of God . . . the other persons who are engaged in carrying the stones . . . also are holy angels of the Lord . . . [And] when the tower is finished and built, then comes the end’” (The Shepherd 1:3:1–8 [A.D. 80]).
