Jesus condemned Pharisees to hell, meaning they weren't worshipping God rightly either...
The obedience to the Jew’s teachings of the Laws of Moses was only temporary. This was only in view of the Jews, as well. Remember, the Gentiles were only included later in God’s program after Christ was risen. Nowhere does Scripture say that after Christ had risen that Gentile Christians were to go to the Jews and obey them. Gentiles were not even to obey the Laws of Moses according to Acts 15:1, Acts 15:5, and Acts 15:24. So this does not apply. We are not under the Law (i.e., the Law of Moses, the 613) according to Paul. Yes, certain laws have carried over or repeated in the many laws given to us by Jesus and His followers (like do not murder, do not steal, do not covet, etc). But when Jesus died upon the cross, the New Covenant began and the Old system with the 613 laws of Moses had ended. Gentiles are not obligated to keep the laws of Moses.
