Clearly, Apostles and early Christians rejected from the very beginning (and they were all observant Jews at that time), as evidenced in Acts 5, the notion that Gentiles are subject to the Law just as we do not consider European citizens subject to American laws but hold them to moral laws, which apply universally.
The error of Judaism is that it has monopolized God to the point that it is felt that the only way to know God is to become an observant Jew. In that, Judaism fails the Old Testament, which clearly states that "in thee all nations will be blessed." It was through the New Testament, as interpreted in Acts 5 by Saint Peter, that the God of Abraham is made known to all the nations to worship.
It is through the NT that the OT is correctly delivered.
That's the same exact argument I'm making. The moral law is the law of love and the ten commandments are the written expression of the law of love.
Judaism has always allowed for gentiles to know God. Judaism considers all nations as God's children. Christianity considers only believers to be God's children and everyone else damned. Monopoly? I believe you point the finger in the wrong direction.
