Is there a Christian denomination that teaches that God cannot heal?

Prompted by a Meta conversation this question asks if there are any Christian denominations which teach that God cannot heal our physical bodies in the here and now. I am not asking after teachings regarding when, if, or how God may or may not heal. I am asking if any Christians officially, denominationally teach that God cannot ... that it is impossible for Him. Not that He "does not" but that He "cannot".
