Well we know the authorities are not magic-based, at least not in the sense of using the user's Mana or Od.

It most likely has to do with Ying-Yang. The Authorities being Yin and the Blessings being Yang, which would explain the obvious similarities.

However the fact that it says "swallow the world" does point to what she did around the tea-party when she took over Emilia, which is more than likely related to Authorities rather than Mana.

I do like your theory though, I think it's well thought-out and quite possibly has a bit of truth to it as to why Beatrice was created in the first place and such.
