Augustine of Hippo
Catena Aurea · Johannesevangelium 8
Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; And ye shall know the truth, and the truth shall make you free. They answered him, We be Abraham’s seed, and were never in bondage to any man: how sayest thou, Ye shall be made free? Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin. And the servant abideth not in the house for ever: but the Son abideth ever. If the Son therefore shall make you free, ye shall be free indeed. And ye shall know the truth.
(Tr. xli. 1) As if to say: Whereas ye have now belief, by continuing, ye shall have sight. (xl. 9.). For it was not their knowledge which made them believe, but rather their belief which gave them knowledge. Faith is to believe that which you see not: truth to see that which you believe? By continuingthen to believe a thing, you come at last to see the thing; i. e. to the contemplation of the very truth as it is; not conveyed in words, but revealed by light. The truth is unchangeable; it is the bread of the soul, refreshing others, without diminution to itself; changing him who eats into itself, itself not changed. This truth is the Word of God, which put on flesh for our sakes, and lay hid; not meaning to bury itself, but only to defer its manifestation, till its suffering in the body, for the ransoming of the body of sin, had taken place.
