I would like to know if there is an exhaustive list of all common venial and mortal sins or, at least, most common venial and mortal sins. It could in a certain sense be useful. I know mortal sins are usually said to be tied to the 10 commandments one way or another, but I think it wouldn't be out of touch to have additional explicit lists.

The 7 capital sins, which give rise to other sins, can be mortal:

  1. Pride
  2. Greed
  3. Lust
  4. Anger
  5. Gluttony
  6. Envy
  7. Sloth


St. Thomas Aquinas's Summa Theologica II-II devotes separate questions (collections of articles) to the following, which are or can be sins or vices; for many of them, he discusses whether they can be mortal (many of them can be):

10. Unbelief in General
11. Heresy
