Do we still use the terms mortal and venial in reference to sin?

Question:

Answer:

Mortal (deadly) and venial are still terms used by the Church to distinguish serious sin from less serious sin (cf. CCC 1855). Mortal sin is mentioned also in 1 John 5:16–17: “If any one sees his brother committing what is not a mortal sin, he will ask, and God will give him life for those whose sin is not mortal. There is sin which is mortal; I do not say that one is to pray for that. All wrongdoing is sin, but there is sin which is not mortal.”
