Government became involved in marriage when questions of faithfulness and inheritance became subject to dispute.
In this respect agree with you. However in the respect of licencing marriages rather than simply recognizing that which has already happened by the power of God and thus implications there to I agree that Government has no business.
Government does not and Cannot form(or for that matter break) a marriage, it can merely recognize it’s existence in terms of legal implications.
I would thus propose that the question is not so much about the unfailing sinful foolishness of the State and Sodomites around us but of yourself.
Do we recognize the unions of Sodomite as legitimate? I would say absolute not. Its time to tell theses people that, they are not really bounded and have no real moral obligation.
Their only real marriage has been to that of Sin, and we believe in Redemption.
Urge them to leave Sodomy behind and Imply in no uncertainty terms that includes the one to whom they claim to be bonded.
What they call a marriage is a lie, and that is in no meaningfull way a marriage.
Hate the sin love and remind the sinner of their path to redemption!
So countless thousands of years, since there has to be something known as a legal marriage.
When in American history was marriage considered legal, based on whatever a mosque, or cult, or gay church, or Mormon Temple, said, just because they were a religion?
Is that what you are calling for now? What do you think your chances are of ending the need for law in marriage and divorce? Even Thomas Jefferson (marriage license bought 1771) dealt in divorce law as an attorney, the federal government was passing laws in regard to marriage in the 1780s and 1790s.
