I personally think it only stands to reason that we need to accept Oral Torah. However, that means we need a community to present it to us, since the Orthodox have their version of Oral Torah, the Conservatives have theirs, MJRC has theirs, etc.
But with you, I'm lowering the bar. I'm asking ONLY that you not set yourself up as the Judge to determine for yourself what the interpretation of Torah is. No one made you Judge. You say in your post above that you have not separated yourself from community, but everything else you have said screams that you have -- IOW there is an inconsistency between what you claim and what you say you do.
Yeshua is our greatest Rabbi, but he has given us authoritative teachers to guide us on our way. In the NT, we have the Apostles and their successors. In the OT we have the judges/pharisees/rabbis. Like Paul, I advocate giving honor to whom honor is due, and not setting myself up as Pope.
