Augustine of Hippo
Catena Aurea · Johannesevangelium 14
Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. If ye had known me, ye should have known My Father also; and from henceforth ye know him, and have seen him.
(Tr. lxix. 1) Our Lord had said that they knew both, Thomas says that they knew neither. Our Lord cannot lie; they knew not that they did know. Our Lord proves that they did: Jesus saith unto Him, I am the way, the truth, and the life.
