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.
(super Joan. Tr. xl. 10. et seq.) The first stage of freedom is, the abstaining from sin. But that is only incipient, it is not perfect freedom: for the flesh still lusteth against the spirit, so that ye do not do the things that ye would. Full and perfect freedom will only be, when the contest is over, and the last enemy, death, is destroyed.
