Like I said, what he taught had nothing to do with Judaism. Once it departed from Jewish teaching, it became something else entirely.
The entire idea of the Christian messiah (even without the Trinity) is incompatible with Judaism.
I suggest that it is more than compatible. It's the natural progression of the faith. Many refuse to acknowledge how and why, but it's compatible just the same. Is there not more to the Jewish faith than strict written Jewish law? I know there is, but there is likewise room for growth, no? Paul teaching liberation from these strict written laws per Jesus does not make Jesus being the messiah incompatible with Judaism.
I view it a lot like looking at the glassy surface of a body of water. What you see on the surface is only skin deep. There is much more hidden underneath the surface. All I'm suggesting is that many people's honor seems to be only skin deep and religiously motivated. Jesus and Paul both suggested that God desires us to break through the skin (self will/flesh) and get to the spirit of the law instead of just obeying because we think we are required to.
It's a natural progression and not one we can force on ourselves OR on others. It's about true blue spiritual progress and not about religious demands. It's an issue of heart (spirit), and not so much about the will (flesh). Judaism seems to be more about "self will" and obedience whereas Jesus, Paul, and the apostles all taught about matters of heart (spirit).
I'd much rather prefer my son to truly love me with all his heart and honor me through himself instead of displaying a colder type of love by merely doing what he thinks I demand of him. One is pleasant and easy to be entreated. The other is burdensome and hard. Paul truly believed he was teaching progression of the Jewish faith. I do to. You don't. It's all good.
