John's narrative avoids this difficulty by supposing the intimation that Judas was the man to be conveyed by a private signal understood only by Peter and the disciple next to Jesus. These two may have felt it necessary to keep the secret, but why then could they not understand the words of Jesus to Judas, or why not at least inquire whether they had reference to his treachery, which had just before been so plainly intimated? That Jesus, with his keen vision, may have divined the proceedings of Judas, is quite possible; that he could have spoken of them at the table in this open way without exciting more attention, is hardly credible. It was at this same passover that Christ, conscious of his approaching end, blessed the bread and the cup of wine, and giving them to his disciples, told them that the one was his body, and the other his blood in the new testament, or the new testament of his blood (Mk. xiv. 22-25; Mt. xxvi. 26-29; Lu. xxii. 14-21; I Cor. xi. 23-25). John who was confused about dates in his biography, supposes that this supper took place before the feast of the passover, instead of at it, and, consistently with this view, he says nothing of the institution of the Eucharist, which had a peculiar reference to the Jewish feast-day. Instead thereof, he introduces another ceremony, of which neither the other Evangelists nor Paul say a word; that of washing the disciples' feet by Jesus. This was done to make them "clean every whit" (though it had no such effect on Judas), and also to set them an example of mutual kindness (Jo. xiii. 4-17).
