Behold our refutation of the error. It is not based on documents of faith, but on the reasons and statements of the philosophers themselves. If then anyone there be who, boastfully taking pride in his supposed wisdom, wishes to challenge what we have written, let him not do it in some corner nor before children who are powerless to decide on such difficult matters. Let him reply openly if he dare. He shall find me there confronting him, and not only my negligible self, but many another whose study is truth.

The magnitude of the punishment matches the magnitude of the sin. Now a sin that is against God is infinite; the higher the person against whom it is committed, the graver the sin-it is more criminal to strike a head of state than a private citizen-and God is of infinite greatness. Therefore an infinite punishment is deserved for a sin committed against Him.
