Wilson was indeed a nominal minister. That was not his primary, or even his secondary calling. He was a Ph.D., full professor and president of Princeton University at the time of his election in 1912. Your post discloses a great deal by saying too little.
I know he was a professor,but I would have sworn I read he was a minister as well.
Anyhow, it's actually secondary to the point. There isn't much debate that he had the same "God Complex" that they accuse Bush of having. He told a man once that "No power on earth" could have stopped him from becoming President because God wanted it, and to him, that essentially meant whatever he wanted to do was what God wanted him to do.
