But what has been said about a good purpose, I wish to have understood with caution. For a good purpose ought to be twofold. First, a purpose with regard to open, mortal sins, such as adultery, homicide, fornication, theft, robbery, usury, slander, etc. The purpose to avoid these sins belongs properly to sacramental Confession, and to confession before God it belongs at any moment after the sins have been committed; according to the word of Ecclesiasticus, "My son, hast thou sinned? Do so no more, but ask pardon for thy former sins," [Ecclus. 21:1] and again, "Make no tarrying to turn to the Lord." [Ecclus. 5:8] In the second place, however, as regards all the sins they call "venial" (of which more below), it is entirely vain to labor after the forming of a good purpose, because if one rightly considers himself, he will find such a purpose altogether impossible, if he wishes henceforth to live in the flesh; since (as Augustine says) this life cannot be lived without such sins as unnecessary and thoughtless laughter, language, imaginations, sights, sounds, etc. As regards such things it is uncertain whether they are sins, or temptations by which merit is increased. And yet it is marvelous how a patent is vexed and worried in these matters by the present wordy manner of confessing. A purpose ought to be certain, and directed toward things which are certain and which can be shunned in common living, like the aforesaid open, mortal sins. SIXTH [Sidenote: Hidden Sins—Are They to be Confessed?] Whether the hidden sins of the heart, which are known only to God and the man who commits them, belong to sacramental confession or not, is more than I can say. I should prefer to say that they do not. For the need of confessing these sins can in no way be proved, either by reason or by Scripture, and I have often suspected that it was all an invention of avaricious or curious or tyrannical prelates, who took this way of bringing the people of Christ to fear them. This is, in my opinion, laying hands on the judgment of God and is a violation of the rights of God, especially if men are forced to it.[5]
