Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law. 15 They show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts sometimes accusing them and at other times even defending them.
So by using Man made law, all manner of unforseen consequences are felt at a later time. It is this reason why Gay Marriage is Constitutional. It is, in my opinion, undesirable, certinly anti Biblical, but it is NOT unConstitutional. The Founder's expressly removed God from government, and so your assertions that America told God to go away I believe, are correct - and 220 years late.
