As if the apostle had said, Avoid and shun, and refuse communion with, him that doth obstinately persist in dangerous errors and heresies, and accordingly let him be excommunicated.
Learn hence, 1. Who is an heretic in the apostle's sense; even he who is preverted from the true faith, and holds opinions which subvert the foundations of it; and one who is condemned in his own conscience, and sins against his own convictions: for the apostle here bids Titus not to inform him of his fault, which shows him that the crime lay not in his head, in his understanding, but in his will and affections: for no man who acts according to his judgment and conscience, how erroneous soever, is self-condemned in that action.
Learn, 2. That even heretics themselves ought to be tenderly and lovingly dealt with, so long as there is any hope that they may be gained or won.
Learn, 3. That the charity of the church, in her censure of excomminication, aims rather at the cutting off errors than of persons.
