Should I follow the Ten Commandments or the Mosaic Laws?

If you are a Christian or looking to be one following the Ten Commandments is better than the Mosaic Laws. God wrote the Ten Commandments on a tablet and gave it to Moses. However, Mosaic laws are the laws Moses wrote. For example Sadducees believed strongly in the Mosaic Laws that they condemned Jesus for forgiving others sins. They thought healing was one thing but forgiving was a sin on Jesus part. Jesus died on the cross as a redeemer for our sins.
