There are at least four distinct purposes of the law for Christians today, and each follows from the last.
Keeping God’s Law Perfectly (Catechism XIII)
Man can do whatever he wants, but he only ever wants to do evil.
The Sixth, Seventh, and Eighth Commandments (Catechism XI)
Loving your neighbor is mostly about minding your own business.
Our Only Hope in Life and Death (Catechism I)
We honor God when we are not only serious about keeping our hands from murder, but equally serious about repenting of gluttony.
