“If that is accomplished, what’s to stop the Federal Gov’t from trying to force religious institutions to perform these same sex marriages?”
My worst fear. Will my pastor have to choose between jail and freedom to practice his religion?
No, but he might have to stop performing "marriages" since that definition now belongs to the government and is used to describe a benefits-sharing arrangement between any two individuals who choose to sign the official papers.
Instead, the church will now need to come up with some new term for their ceremony - "covenant" or "holy union" or some such, that does not infringe upon the government's new trademark.
