What a ridiculous way to sidestep the point I made. I AM Catholic. Therefore, I cannot, as you state, “Have my religious marriage and leave the government out of it.” Maybe there are those who are so poorly committed to their faith that they would set it aside in order to avoid a bit of governmental intrusion. My faith means more to me than that—I obtained a marriage license form the state of Michigan, not with a smile on my face, but because for whatever reason that’s what the Church required of me in order to receive the sacrament.
It wasn’t a sidestep, but I can’t account for every church denomination, every religion, every cult, etc.
If your church, your religious practice, REQUIRES you to go to the government, then that is something entirely different.
The Catholic church and government goes hand in hand, they used to make the marriage law for the people that they had the power over, but not in America.
