John Chrysostom
Observe, however, that here also he says: not from among the newly converted. The expression "let these also first be tested" means the same as what he said about bishops. Thus he shows the inner connection, since there is nothing intermediate here. Therefore he used there also the expression "not newly converted." Is it not unreasonable that in a private house a newly purchased slave is not entrusted with any household task before long testing proves his disposition, yet in the Church of God one who has entered from outside is immediately placed among the most honorable?
