12 Moreover, what is the meaning of that which Stephen would assert, that the presence and holiness of Christ is with those who are baptized among heretics? For if the apostle does not speak falsely when he says, “As many of you as are baptized into Christ, have put on Christ,” certainly he who has been baptized among them into Christ, has put on Christ. But if he has put on Christ, he might also receive the Holy Ghost, who was sent by Christ, and hands are vainly laid upon him who comes to us for the reception of the Spirit; unless, perhaps, he has not put on the Spirit from Christ, so that Christ indeed may be with heretics, but the Holy Spirit not be with them.
