But again, even those who sufficiently understand that he who is not in the body of Christ cannot be said to eat the body of Christ, are in error when they promise liberation from the fire of eternal punishment to persons who fall away from the unity of that body into heresy, or even into heathenish superstition. For, in the first place, they ought to consider how intolerable it is, and how discordant with sound doctrine, to suppose that many, indeed, or almost all, who have forsaken the Church catholic, and have originated impious heresies and become heresiarchs, should enjoy a destiny superior to those who never were catholics, but have fallen into the snares of these others; that is to say, if the fact of their catholic baptism and original reception of the sacrament of the body of Christ in the true body of Christ is sufficient to deliver these heresiarchs from eternal punishment. For certainly he who deserts the faith, and from a deserter becomes an assailant, is worse than he who has not deserted the faith he never held. And, in the second place, they are contradicted by the apostle, who, after enumerating the works of the flesh, says with reference to heresies, "They who do such things shall not inherit the kingdom of God."
