We must take heed that the unworthiness of some men does not cause us to be slack in well-doing. We must have no familiarity or fellowship with the one who has been excommunicated. The end of the excommunication is not the destruction, but the salvation of the sinner, that at least through shame he may be driven to repentance. We must avoid familiarity with the one who has been excommunicated in such a way, that we diligently seek every occasion and means that may be, to bring them again into the right way. Now the Lord of peace himself give you peace always by all means.
Prayers are the seals of all exhortations.
The apostle writes the conclusion of his letter with his own hand, so that false letters might not be brought and put in place of true ones.
