There is no singular or "ultimate" Messiah. I expanded on this earlier in the thread - I can find it for you if you like.

That said, there are individuated souls who have either communed with the Creator, or something they perceive to be the Creator, and share what they experienced and learned with others. It is up to us to review this sharing cautiously yet openmindedly, so we may intuit for ourselves what is pertinent or truthful to us and what may not be.
