Do any of the Messianic believers in Jesus read and live according to the Jewish oral law and tradition?

No remember they believe Jeremiah 31 is not a New Covenant based on the law when Verse (33) proves it is. Christians aren't worshiping Yahweh. If they would know how to read Hebrew prophesy they would know that even the messiah would have taught the laws. When all this becomes clear it is very easy to see that they have created their own god, own messiah and own Religion. The Old Testament and New Testament have nothing in common.
