Upholding freedom and the 1st Amendment isn't really a Christian thing. It's an American thing.
“Freedom of Religion” “No State-funded Church” 1st Amendment is 1st courtesy of the Christian contingent of our founding fathers.
The ones who didn’t want their worship or relationship with God and church interrupted by tyrants and kings or corrupt popes even. Thank them.
Keep State out of church.
It doesn’t say keep God out of State or public life.
