529. The same is the case with those who are in good from the Lord. If from will and understanding, or purpose and confirmation, they abstain from one evil because it is a sin, and still more if they abstain from several, they abstain from all; for as soon as one from purpose or confirmation abstains from any evil because it is a sin, he is held by the Lord in the purpose of abstaining from the rest. Therefore, if he does evil from ignorance or from some prevailing concupiscence of the body, it is not imputed to him because he did not propose it to himself and does not confirm it with himself. A man comes into this purpose if once or twice a year he examines himself and repents of the evil which he finds in himself. Not so with one who never examines himself. From this it is manifest who it is to whom sin is not imputed, and who it is to whom it is imputed.
