Forgiveness is no cure for such Evil; much less vicarious forgiveness.

Those, therefore, who ought to expel Evil from mankind by a visible working, lo, they are purging away the sins of mankind by an invisible forgiveness. But though the sins of mankind do not depart from them they are added to those who (say that they) purge them sevenfold. For around their necks is hung the debt of sins for the pardon of which they have falsely gone surety. For also madness, though it does not depart from a dog which has gone mad, enters sevenfold into those who are bitten by the dog. [St. Matt. x. 14.] But the disciples were commanded that they should shake the dust off their feet against whoever did not receive them, [ Ov. p. 52.] let us shake off the dust of our words against these who do not receive the Truth of our words. For if vengeance was ready to come for the dust of feet, how much more ready will vengeance be for the Truth of a word which is treated despite-fully by him who hears !
