Sin

Jesus on origin of sin

For from the heart come evil thoughts, murder, adultery, unchastity, theft, false witness, blasphemy.

• St. Paul on sins or "works of the flesh":

Now the works of the flesh are obvious: immorality, impurity, licentiousness,
idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions (Gal 5:19-20)

Classifications of Sin

From CCC 1853

Sins can be distinguished according to their objects, as can every human act; or according to the virtues they oppose, by excess or defect; or according to the commandments they violate. They can also be classed according to whether they concern God, neighbor, or oneself; they can be divided into spiritual and carnal sins, or again as sins in thought, word, deed, or omission. The root of sin is in the heart of man, in his free will, according to the teaching of the Lord: "For out of the heart come evil thoughts, murder, adultery, fornication, theft, false witness, slander. These are what defile a man." But in the heart also resides charity, the source of the good and pure works, which sin wounds.

which we can organize as

	by their objects by the virtues they oppose by the Commandments they violate
	against God against neighbor against oneself
