So let me see if I get this. It would be changing it so all people who want to be married would only get Civil Unions from the government and it wouldn't be recognized as a marraige unless the churches and people want it?
Not exactly. The government would recognize only civil unions; the term marriage will be unknown to the law, and irrelevant to the government.
Right. People could define marriage however they like, having the government leave the spiritual aspect of it to them, and government would simply give what it recognizes as 'marriage' now the label civil union, which in the eyes of government is really what that is(government doesn't require love or commitment before God or anything of that sort to marry, it's simply a contract).
