Now when they who teach the mysteries of Mithra say that he was born from a rock, and call the place where they teach the initiation of them that obey him a cave, do I not know that they have imitated the saying of Daniel: a stone was cut without hands out of a great mountain? And similarly with the words of Isaiah, all of whose sayings they have tried to imitate? For they have so devised that words urging acts of righteousness are even spoken among them.
Now I must perforce relate to you the words that Isaiah has said, that you may know that this is so. They are as follows: Hear, ye that are far off, what things I have done. They who draw near shall know my strength. The lawless in Sion have departed; trembling shall seize the ungodly. Who will announce to you the everlasting place? One that walks in righteousness, speaking straight, hating iniquity and injustice, with his hands kept pure from gifts, closing his ears from hearing unjust judgment of death, shutting his eyes from seeing injustice — he shall dwell in the high cave of a strong rock.
Bread shall be given him, and his water is sure. Ye shall see the King with glory, and your eyes shall see afar. Your soul shall meditate on the fear of the Lord. Where is the writer? Where are the councillors? Where is he that numbereth them that are to be fed, be the people great or small? For with Him they took not counsel, nor knew the depth of (His) speeches, so that they did not hear; a worthless people, and he that heareth understandeth not.Isaiah 33:13-19
It is plain therefore that in this prophecy he speaks of the bread which our Christ taught us to do in remembrance of His incarnation for those that believe on Him, for whom He became even liable to suffering; and also of the cup which He taught us as we give thanks to do in remembrance of His blood. And this prophecy declares that we shall see this very King (surrounded) with glory.
And these texts of prophecy cry aloud that a people which was foreknown as about to believe on Him, was foreknown as about to meditate on the fear of the Lord. And that they who think they know the very letters of the Scriptures, and hear the prophecies, have no understanding, these Scriptures have likewise proclaimed. But Trypho, I said, when I hear that Perseus has been born of a virgin, I understand that the deceitful serpent has done this also by way of imitation.
