Everything that is in the ten commandments, has been restated and deamed important by christ.
You must look at the context of the Ten Commandments, they were written as the law, a way to possibly gain a place with the God of Israel. Now we have Christ, Salvation is not gained by following the law or deeds, it is gained through Jesua. The Ten Commandments are a good guide to live our lives, but not the law.
