Saint Anselm

“ What contempt man brought upon God, when he allowed himself to be conquered by the devil; for which he can make no satisfaction. Chapter XXIII: What man took from God by his sin, which he has no power to repay. Chapter XXIV: How, as long as man does not restore what he owes God, he cannot be happy, nor is he excused by want of power. Chapter XXV: How man's salvation by Christ is necessarily possible. ”

“ How the redemption of man could not be effected by any other being but God. Chapter VI: How infidels find fault with us for saying that God has redeemed us by his death, and thus has shown his love towards us, and that he came to overcome the devil for us. Chapter VII: How the devil had no justice on his side against man; and why it was, that he seemed to have had it, and why God could have freed man in this way. ”

“ How nothing less was to be endured, in the order of things, than that the creature should take away the honor due the Creator and not restore what he takes away. Chapter XIV: How the honor of God exists in the punishment of the wicked. ”
