Traditional marriage is made up of two parts, civil and religious.
1) You must obtain a marriage license from the state and it must be signed by both you and your spouse and an official designated by the state, and then must be filed with the state. This is a civil contract.
2) The second part, religious, is the blessing of the church and the sanctification of your union by God.
It appears that the second part is what the gay community desires for they are already allowed the civil union, which is their right under law. Then the issue in “gay marriage laws” is to force the “church’ to recognize them through legislative and judicial means thus gaining the ‘blessing’ of God who has declared their life style sinful and an abomination.
