Therefore if any man be in Christ, he is a new creation: old things are passed away; behold, all things are become new.
All Commentaries on 2 Corinthians 5:17 Go To 2 Corinthians 5
John Chrysostom
AD 407
For seeing he had exhorted unto virtue from His love, he now leads them on to this from what has been actually done for them; wherefore also he added, If any man is in Christ, he is a new creature. If any, says he, have believed in Him, he has come to another creation, for he has been born again by the Spirit. So that for this cause also, he says, we ought to live unto Him, not because we are not our own only, nor because He died for us only, nor because He raised up our First-fruits only, but because we have also come unto another life. See how many just grounds he urges for a life of virtue. For on this account he also calls the reformation by a grosser name , in order to show the transition and the change to be great. Then following out farther what he had said, and showing how it is a new creation, he adds, The old things are passed away, behold, all things are become new.
What old things? He means either sins and impieties, or else all the Judaical observances. Yea rather, he means both the one and the other. Behold, all things have become new.
