Thank you for the reply.
Many Jewish sects have many different views. For the last 2 or so millennia this has been true. Same for Christians, Muslims, etc.
The Jewish Apostles were no different from Adam, Abraham, Isaac, Jacob, Moses, etc. They had belief based on an event they witnessed prophesied by G-d.
You are correct. On my own I have no idea, but G-d’s Word and Works tell me all that is needed to be known.
Oh, but you're incorrect. The "Jewish" apostles left their faith to join the JC movement. I don't know to which "G-d" you are referring, but it wasn't any event mentioned in the Torah.
