2 Corinthians 3:2

Ye are our epistle written in our hearts, known and read of all men.

Ye are our epistle ... The Corinthian church, in a figurative sense, was Paul's letter of recommendation.

Written in our hearts ... The RSV has "written in your hearts" which is probably the better rendition. Clines called the RSV "preferable" in this place,[10] despite the fact of its manuscript support being weaker. In context, the Corinthians are the letter; and since all people can read it, it would have to be written in their heart rather than Paul's for this to be possible. Had it been written in Paul's heart only, who could have read it? The heart of the formerly reprobate Corinthians, now converted, however, was where the writing had taken place. Such changes as had taken place in them (due to a change in heart) upon their conversion were indeed visible to the whole world of that period. "The metaphor is that the Corinthian church was itself the epistle of Christ";[11] and Paul's laying claim to the epistle as his is a reference to his having established their congregation through the preaching of the gospel. In verse 5, Paul made it clear that in the higher sense he considered God to be the true author of the epistle, that is, of the conversions at Corinth.
