Having same-sex marriages, but not calling them marriages, falls short of having equality for homosexuals.
Marriages are civil contracts under the law. I don't think religious ceremonies should have any bearing on a citizens relationship, under law, with their government.
If you have religous beliefs, so be it. Go have what ever bonding ceremony is advocated by that religion. It's should give you any extra responibilities or prilevgeds, under the law though. You are doing it for religious reasons in the first place right?
If you want to have the responsbilities and privledges of a marriage, then get a marriage licence, go see a justice of the peace.
Of course nothing is stopping someone from doing both.
