From Anselm, Cur Deus Homo [/Why God Became Man], (Canterbury, AD 1098). Book I, Chapter XV.
Nothing can be added to or taken from the honor of God. For this honor which belongs to him is in no way subject to injury or change. But as the individual creature preserves, naturally or by reason, the condition belonging, and, as it were, allotted to him, he is said to obey and honor God; and to this, rational nature, which possesses intelligence, is especially bound.
And when the being chooses what he ought, he honors God; not by bestowing anything upon him, but because he brings himself freely under God’s will and disposal, and maintains his own condition in the universe, and the beauty of the universe itself, as far as in him lies. But when he does not choose what he ought, he dishonors God, as far as the being himself is concerned, because he does not submit himself freely to God’s disposal. And he disturbs the order and beauty of the universe, as relates to himself, although he cannot injure nor tarnish the power and majesty of God.
… And so, though man or evil angel refuse to submit to the Divine will and appointment, yet he cannot escape it; for if he wishes to fly from a will that commands, he falls into the power of a will that punishes. And if you ask whither he goes, it is only under the permission of that will; and even this wayward choice or action of his becomes subservient, under infinite wisdom, to the order and beauty of the universe before spoken of.
For when it is understood that God brings good out of many forms of evil, then the satisfaction for sin freely given, or if this be not given, the exaction of punishment, hold their own place and orderly beauty in the same universe. For if Divine wisdom were not to insist upon things, when wickedness tries to disturb the right appointment, there would be, in the very universe which God ought to control, an unseemliness springing from the violation of the beauty of arrangement, and God would appear to be deficient in his management. And these two things are not only unfitting, but consequently impossible; so that satisfaction or punishment must needs follow every sin.
