The should be two seperate unions of a couple.
1) The civil union, a legal contract executed at your local courthouse. A religion's minister should not be acting as an agent of the government, and I know at least some ministers agree with such.
2) The religious marriage, a union in God's eyes.
A couple, be they hetrosexual or homosexual, may choose to do one or the other or both. But it would be the civil union that would define the legal status of the couple and how it affects their rights and obligations in society.
