Q.88: Are all transgressions of the law equally heinous?
A. Some sins in themselves, and by reason of several aggravations, are more heinous in the sight of God than others.
If anyone sees his brother sinning a sin which does not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that. 1 John 5:16
