There are some pretty intriguing commandments in the Bible. In total, there are a whopping 613. These commandments range from not eating worms found in fruit to burning cities that have engaged in idolatry worship. I'm still trying to understand how Christians decide which commandments can be tossed out of the window and which are still mandatory to follow.
For example, let's take these two:
1 Corinthians 14:34 Women should remain silent in the churches. They are not allowed to speak, but must be in submission, as the law says.
Leviticus 18:22 Do not lie with a man as one lies with a woman; that is detestable.
Can someone please explain to me the process Christians use to determine that the first commandment is no longer necessary but the second one still is? Thanks.
The 613 commandments are those enumerated by the rabbis as being found in the Torah.
"Women should remain silent..." isn't one of the 613 commandments in the Torah since 1 Corinthians isn't the Torah but a letter penned by Paul and part of the Christian New Testament.
As far as Torah is concerned it simply isn't relevant to Christians. For the same reason that United States law is not applicable to Belgians.
There is no expiration date on those commandments, it's simply a matter of them not being relevant for people outside of their scope. Torah applies to Jewish people only, it is an intrinsic part of the covenant which God made with ancient Israel and is essential to their identity as a people, as marking them the covenant people of God.
Christianity =/= Judaism.
Christianity is based upon the premise that Jesus of Nazareth is the promised Messiah or Christ, and that the Messiah having come as was promised, and having suffered death at the hands of the Romans and being raised up from the dead, and now ascended and seated at the right hand of God reigning as Lord and King over all has set to consummation the ancient promises which God made to Abraham, Israel, and David. That in the Messiah God is constituting the new creation, beginning in Jesus who has overcome death in His own body, and extending to those who believe in Him, being baptized into Him, as His Church are a people of God's kingdom, a people of God's new world, a people of the Risen and Reigning Christ; and they are of every background, they are Jews and Gentiles, slaves and freemen, they are men, women, Romans, Greeks, Scythians, Barbarians, they are black, and white, and brown, and every color of skin under the sun. They speak in all the many tongues of men.
In Christ the solemn promise to Abraham that he would be the father of a great nation, the father of many nations, is come to pass as the Gospel goes out and brings into the Church the many tribes, tongues, and nations of humanity across the globe into the unity of our one Baptism, into the unity of the one new Man, Jesus Christ.
The Torah simply doesn't play any practical role for us in the Church, because it wasn't meant for us.
If you want to understand what it means for people who do follow God's Torah, there are millions of Jews in the world, and there are places online where you can ask questions or learn about Judaism and the Jewish observance of the Torah. But orthodox Christianity does not observe the Law of Moses.
