I am a libertarian and also a Christian. Many if not most libertarians I speak to are also Christians.
Many Christians do not support gay marriage. I also do not support gay marriage but I realize that marriage licenses were first used in this country to stop whites and blacks from intermarrying. George Washington did not have a marriage license. Was he living in sin? I personally don’t want the government telling me what is acceptable or giving me permission to do something that God has already gave me a right to do.
My parents had a marriage license and when I was about five months old my father left us. That marriage license was nothing but a waste of money. It is also common to hear about how gays will go to hell and I am not doubting that but we very seldom hear people condemn fornication or adultery this aggressively but the Bible tells us that they are both sins.
Another argument is that God will destroy America if gays live together remember Sodom. Yes I do remember Sodom and if we read the whole story it tells us in Genesis 18:33 that it would not have been destroyed if only ten righteous people could be found in the city.
If you have a right from God to do something you don’t need a license. In the day of judgment God will decide who is correct and who is incorrect not the government or the president who are supporters of the United Nations.
Free speech is also something libertarians love and we support you talking about your religious beliefs in public because the public square is a free speech zone and you don’t have to have permission from anyone to say what is on your mind even if it offends someone.
In closing I would like to remind everyone that the first amendment does not create a separation of Church and state but stops congress from passing any laws establishing religion. I am against the federal governments involvement in education where there is a public funding of the religious belief in Evolution.
