Wed, Wk 5: "what comes out of the man ... defiles"

From within the man, from his heart,
come evil thoughts, unchastity, theft, murder,
adultery, greed, malice, deceit,
licentiousness, envy, blasphemy, arrogance, folly.
All these evils come from within and they defile.”

-- Mk 7:14-23

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.

-- CCC 1853
