With all due respect, friend, I cannot imagine a more wicked solution. Marriage is a sacrament established by God for His people. It is first and foremost and only the business of the Church.
If anything it is the state that should get out of the marriage business. The state can render no other sacrament, nor would the Church have permitted them to, when the Church still had the power to constrain. Will the state now render all the sacraments? Of course not! Why then should they be permitted to officiate at marriage?
Read the post again. It says that perhaps churches should get out of the CIVIL marriage business (i.e., stop acting as agents of the state), but NOT out of administering the SACRAMENT of Marriage.
This already is the case in quite a few other countries, and the Church has lived happily with it. The state has an interest in promoting marriage, regulating divorce, etc., so will not get out of these area. Sacraments are for the Church, however.
If homosexuals want to bond, they can have ‘civil (somethings)’ but they can't have a ‘civil marriage’.
“Marriage” is “marriage”. Between one man and one woman. To call a relationship between two people of the same sex a marriage is to dilute “marriage” to the point it no longer means what it did. Maybe it would mean nothing at all.
