What is Mortal Sin?

Mortal sin is a grievous offense against the law of God.
When does one commit a mortal sin?
One commits a mortal sin when he knowingly and willfully breaks the law of God in a serious matter.

We should look upon mortal sin as a most shameful insult to God, and the greatest evil that can befall man.
