Unless used in the context of the prophecy of Simeon of course.
Yeah, I think there are valid uses for this tag. For example How did Judas die?.
Other questions that use that tag should probably be retagged, since it seems that the questioner was attempting to expose contradictions, but didn't reference any valid contradictions in the bible. (Those are the ones that should be tagged flame-bait)
But I agree that contradictions can be valid and useful. When it's not, it should be edited.
