This is an instance, that a man may say a thing with a good intention, and yet ignorantly to His hurt. Peter, ignorant of our Lord’s deep meaning, at first, as if in doubt, says mildly, Lord, dost Thou wash my feet? and then, Thou shalt never wash my feet; which was in reality to cut himself off from having a part with Jesus. Whence he not only blames our Lord for washing the disciples’ feet, but also his fellow-disciples for giving their feet to be washed. (c. 6.). As Peter then did not see his own good, our Lord did not allow His wish to be fulfilled: Jesus answered and said unto him, If I wash thee not, thou hast no part with Me.
