While it may be problematic, churches can teach all the courses on constitutional law they want. That's freedom of religion.

The church may inject its own viewpoints into the Constitution class and what it think of the Constitution, but separation of church and state shouldn't mean that they couldn't teach such a class.

and state.

I WILL assume that they are teaching a pack of lies about the Constitution, however, so it IS an argument for slapping somebody upside the head.

"P.S. A point of clarification: These zeebs are free to use their First and Second Amendment rights, as we see them doing (Mr. Blunt and Cranky is a Presbyterian who uses all of his Constitutional rights, after all). The reason separation of church and state was brought up here is this: entirely too many Americans (including elected and appointed “representatives” and officials at all levels and in all branches of government) want to trash the Establishment clause and make our nation into a Fundagelical Theocracy.

One thing our Founders knew well were the dangers of such a form of government, but too many of us have forgotten. So when we see churches like this one arming themselves and seeking political power, we need to be aware of the threat they pose."

Although questioning what you are reading probably goes against their logic.
