You're right:

A foreign language film is defined, for Academy Award purposes, as a feature-length motion picture produced outside the United States of America with a predominantly non-English dialogue track.

I thought this might be something that the Academy would have to deal with. I guess not.

Foreign Language films can however be nominated for Best Picture without anyone's consent. Il Postino in 1994. 'La Vita e Bella'(gag) in 1998. I don't think that will happen, not from any anti-religious bias, but because simply not enough people who vote liked the film that much. Just a matter of taste.
