“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?”
John 18:26 — Greek Interlinear
Church Fathers on John 18:26
After the Evangelist has said that they sent Jesus bound from Annas to Caiaphas, he returns to Peter and his three denials, which took place in the house of Annas: And Simon Peter stood and warmed himself. He repeats what he had said before.
Or, He means that the once fervid disciple was now too torpid, to move even when our Lord was carried away: strewing thereby how weak man’s nature is, when God forsakes him. Asked again, he again denies: They said therefore to him, Are not you also one of His disciples? He denied it, and said, I am not.
Mystically, by the first denial of Peter are denoted those who before our Lord’s Passion denied that He was God, by the second, those who did so after His resurrection. So by the first crowing of the cock His resurrection is signified; by the second, the general resurrection at the end of the world. By the first damsel, who obliged Peter to deny, is denoted lust, by the second, carnal delight: by one or more servants, the devils who persuade men to deny Christ.
