We are NOT voting for Pope!
The people in our government have the power to take away religious freedom and in all sorts of way promote and support secular humanism.
What’s more, they aren’t to be lords, but representatives of the people. If Christians don’t speak up, they won’t be represented.
And representative government is self-government. The people aren’t under a dictator, but have a large measure of self-determination. That means that Christians, like other citizens, have some governing power. To abdicate that power is to simply allow all those who oppose Christianity to have their way.
