Luke 22:57

Peter denied, because he promised rashly. He does not deny on the mount, nor in the temple, nor in his own house, but in the judgment-hall of the Jews. There he denies where Jesus was bound, where truth is not. And denying Him he says, I know him not. It were presumptuous to say that he knew Him whom the human mind can not grasp. For no one knoweth the Son but the Father. (Matt. 11:17). Again, a second time he denies Christ; for it follows, And after a little while another saw him, and said, Thou wert also one of them.

In this denial then of Peter we affirm that not only is Christ denied by him who says that He is not Christ, but by him also, who, being a Christian, says he is not.

What meaneth it, that a maid is the first to betray Peter, whereas surely men ought the more easily to have recognised him, save that that sex should be plainly implicated in our Lord's murder, in order that it might also be redeemed by His Passion? But Peter when discovered denies, for better that Peter should have denied, than our Lord's word should have failed. Hence it follows, And he denied, saying, Woman, I know him not.

(ut sup.) What ails thee, Peter, thy voice is suddenly changed? That mouth full of faith and love, is turned to hatred and unbelief. Not yet awhile is the scourge applied, not yet the instruments of torture. Thy interrogator is no one of authority, who might cause alarm to the confessor. The mere voice of a woman asks the question, and she perhaps not about to divulge thy confession, nor yet a woman, but a door-keeper, a mean slave.
