Some lists on Sin - 3, 7, 4, 6, 9

We should not be satisfied merely to keep the commandments of God, but should always be ready to do good deeds, even when they are not commanded. The commandments of God state the minimum requirements for salvation. They should be kept not merely according to the letter, but also according to the spirit, which obliges us to strive for greater perfection.

Actual sin is any willful thought, desire, word, action or omission forbidden by the law of God.

3 Conditions for Mortal Sin

Grave matter
Full knowledge
Deliberate consent

Note:  From the Catechism of St. Pius X, "The Main Kinds of Sin," Question 9-10:

Q: What injury does mortal sin do the soul?
A: (1) Mortal sin deprives the soul of grace and of the friendship of God; (2) It makes it lose Heaven; (3) It deprives it of merits already acquired, and renders it incapable of acquiring new merits; (4) It makes it the slave of the devil; (5) It makes it deserve hell as well as the chastisements of this life.

Q: Besides grave matter, what is required to constitute a mortal sin?
A: To constitute a mortal sin, besides grave matter there is also required full consciousness of the gravity of the matter, along with the deliberate will to commit the sin.
