Thank you for posting that link where Rand Paul is concerned.
But he did punt on the issue, as I assumed he would.
While I’m a Cruz supporter Paul came closer to what I think the answer should be. The government has no right to be in the “marriage” business at all. The only reason you need a license is so they can tax and regulate “marriage.” The ceremony should be left to the Church and in the eyes of God not stamped on a piece of paper. Of course the Church (and I’m using this in the general sense not a particular “church”)should have the right based on freedom of religion to deny marrying anyone that doesn’t follow their teachings.
