Do Christians Need to Keep the 10 Commandments?

The short answer is, NO. The long answer is that we should be obedient to the relevant commandments, and they should give us an idea of how to serve God better and keep from sinning.

The 10 commandments can be further simplified by Jesus 2 commandments in Matthew 22:37-39

The only commandment Paul states we don’t have to follow is “Keep Sabbath Holy”, based on Colossians 2:16–17
