To the argument of the Novatians, that they only deny forgiveness in the case of greater sins, St. Ambrose replies, that this is also an offence against God, Who gave the power to forgive all sins, but that of course a more severe penance must follow in case of graver sins. He points out likewise that this distinction as to the gravity of sins assigns, as it were, severity to God, Whose mercy in the Incarnation is overlooked by the Novatians.
