Adventists are contrarians.
Most Christians go to church on Sunday; Adventists go on Saturday.
Most Christians think you go to Heaven or Hell when you die; Adventists believe you go to sleep.
We're a conservative denomination that promotes vegetarianism, for goodness sake!
I don't think Adventism is contrarian in principle. It's not as if our pioneers set out to believe or practice the opposite of other Christians. They just believed you shouldn't do what everyone else does just because that's what everyone does.
