i think it was mainly a scripting thing...I mean, heck, Death spells were all changed to Doom, remember? There was absolutely no lax for 'em. Perhaps BoF squeeked by because it was Capcom or because it wasn't as big when it came out...or both...CT & FFs were fairly big during the SNES era, and they the FFs were some of the only recognized NES RPGs (which are really some of the only games that 'needed' censorship because of godly references and the like.
But, Lordchander, what does describing someone as heavenly connotate really?
