Marriage should NOT be a matter of State. As instituted by God in Holy Scripture it is a sacred covenant. The State has nothing to do with it. But we allow the State to define the terms of the contract when we apply for a “marriage license” - the “benefits” of marriage (a contract sanctioned and controlled under under the State) also include State control over the issue (progeny) of said contract. That which is Holy should never be under State control, period. The first amendment does NOT give power to the State to control religious covenants. State, stay out of the Church!!!!!
That is what the Mormon church wanted in 1862 when the feds first moved against polygamy.
Today the church of Islam and the Episcopalian church supports you as well.
