4 Wherefore, prophecy from ancient times, even from the time when the series of human births began to run onwards, was not silent concerning Christ; but the import of the prophecy was concealed therein, for as yet it was water. Whence do we prove that in all former times, until the age in which the Lord came, prophecy did not fail concerning Him? From the Lord's own saying. For when He had risen from the dead, He found His disciples doubting concerning Himself whom they had followed.
For they saw that He was dead, and they had no hope that He would rise again; all their hope had gone. On what ground was the thief, after receiving praise, deemed worthy to be that same day in Paradise? Because when bound on the cross he confessed Christ, while the disciples doubted concerning Him. Well, He found them wavering, and in a manner reproving themselves because they had looked for redemption in Him. Yet they sorrowed for Him as cut off without fault, for they knew Him to be innocent.
And this is what the disciples themselves said, after His resurrection, when He had found certain of them in the way, sorrowful, “Are you only a stranger in Jerusalem, and hast not known the things which have come to pass there in these days? And He said unto them, What things? And they said, Concerning Jesus of Nazareth, who was a prophet mighty in deeds and words before God and all the people: how our priests and rulers delivered Him to be condemned to death, and bound Him to the cross.
But we trusted that it was He who should have redeemed Israel; and today is now the third day since these things were done.” After one of the two whom He found in the way going to a neighboring village had spoken these and other words, Jesus answered and said, “O irrational, and slow of heart to believe all that the prophets have spoken. Ought not Christ to have suffered all these things. and to enter into His glory? And beginning from Moses and all the prophets, He expounded unto them in all the Scriptures the things concerning Himself.”
And likewise, in another place, when He would even have His disciples touch Him with their hands, that they might believe that He had risen in the body, He says, “These are the words which I have spoken unto you, while I was yet with you, that all things must be fulfilled which were written in the law of Moses, and in the prophets, and in the Psalms, concerning me. Then opened He their understanding, that they might understand the Scriptures, and said unto them, Thus it is written, that Christ should suffer, and rise again from the dead the third day: and that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem.”
