The Creator created marriage. The church, as his instrument in the world, enforces his will.
The rest of your post is not worthy of response as it has nothing to do with the argument of what marriage is and whether government should be defining it!
The rest of my comment is indeed relevant.
Natural Law. Created by the Supreme. No where in the world it doesn’t apply, nor at any time throughout the existence of the universe.
Plus, I don’t agree about churches enforcing His will.
And that statement has nothing whatsoever to do with the topic at hand, anyway.
