8 But since there has been much gainsaying by them, come, let me, with the help of your prayers, (as the shortness of the time may allow,) set forth by the grace of the Lord some few testimonies concerning the Passion. For the things concerning Christ are all put into writing, and nothing is doubtful, for nothing is without a text. All are inscribed on the monuments of the Prophets; clearly written, not on tablets of stone, but by the Holy Ghost. Since then you have heard the Gospel speaking concerning Judas, ought you not to receive the testimony to it?
You have heard that He was pierced in the side by a spear; ought you not to see whether this also is written? You have heard that He was crucified in a garden; ought you not to see whether this also is written? You have heard that He was sold for thirty pieces of silver; ought you not to learn what prophet spoke this? You have heard that He was given vinegar to drink; learn where this also is written. You have heard that His body was laid in a rock, and that a stone was set over it; ought you not to receive this testimony also from the prophet?
You have heard that He was crucified with robbers; ought you not to see whether this also is written? You have heard that He was buried; ought you not to see whether the circumstances of His burial are anywhere accurately written? You have heard that He rose again; ought you not to see whether we mock you in teaching these things? For our speech and our preaching is not in persuasive words of man's wisdom. We stir now no sophistical contrivances; for these become exposed; we do not conquer words with words, for these come to an end; but we preach Christ Crucified, who has already been preached aforetime by the Prophets.
But do thou, I pray, receive the testimonies, and seal them in your heart. And, since they are many, and the rest of our time is narrowed into a short space, listen now to a few of the more important as time permits; and having received these beginnings, be diligent and seek out the remainder. Let not your hand be only stretched out to receive, but let it be also ready to work. God gives all things freely. For if any of you lack wisdom, let him ask of God who gives, and he shall receive. May He through your prayer grant utterance to us who speak, and faith to you who hear.
