Roman Catechism 19.108

Chapter 19 — Part II: The Sacraments — Penance

Section 108. In confession we should employ all that care and exactness which we usually bestow upon worldly concerns of great moment, and all our efforts should be directed to the cure of our soul's wounds and to the destruction of the roots of sin. We should not be satisfied with the bare enumeration of our mortal sins, but should mention such circumstances as considerably aggravate or extenuate their malice. Some circumstances are so serious as of themselves to constitute mortal guilt. On no account whatever, therefore, are such circumstances to be omitted. Thus if one man has killed another, he must state whether his victim was a layman or an ecclesiastic. Or, if he has had sinful relations with a woman, he must state whether the female was unmarried or married, a relative or a person consecrated to God by vow. These circumstances change the nature of the sins; so that the first kind of unlawful intercourse is called by theologians simple fornication, the second adultery, the third incest, and the fourth sacrilege. Again, theft is numbered in the catalogue of sins. But if a person has stolen one golden coin, his sin is less grievous than if he had stolen a hundred or two hundred, or an immense sum; and if the stolen money belonged to the Church, the sin would be still more grievous. The same rule applies to the circumstances of time and place, but' the examples are too well known from many books to require mention here. Circumstances such as these are, therefore, to be mentioned; but those which do not considerably aggravate the malice of the sin may be lawfully omitted.
