Theophylact of Ohrid
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.
When thou art engaged in the practical, He is made thy way; when in the contemplative, He is made thy truth. And to the active and the contemplative is joined life: for we should both act and contemplate with reference to the world to come.
