Augustine of Hippo
Catena Aurea · Johannesevangelium 18
And Simon Peter stood and warmed himself. They said therefore unto him, Art not thou also one of his disciples? He denied it, and said, I am not. One of the servants of the high priest, being his kinsman whose ear Peter cut off, saith, Did not I see thee in the garden with him? Peter then denied again: and immediately the cock crew.
(Tr. cxiii) Lo, the prophecy of the Physician is fulfilled, the presumption of the sick man demonstrated. That which Peter had said he would do, he had not done. I will lay down my life for Thy sake; but what our Lord had foretold had come to pass, Thou shall deny Me thrice. (Luke 22:34)
