Separation of Church and State properly applied means the State should not legally acknowledge any religious institutions, including the Institution of Marriage. When a man and a woman obtain a marriage license from the State they should not be able to go to ANY church or religion to get married. They should ONLY be able to get married by the State, using State public civil law to get married with a State marriage license. The State can have absolutely nothing to do with ANY Church or religious Institution of Marriage, and any Church or religion can have absolutely nothing to do with any State Institution of Marriage. A man and a woman may choose one or the other or both. However if they choose only the Church Institution of Marriage their marriage will only be acknowledged by that Church and not by the State, and vice versa. Human beings can legally acknowledge human physical relations with State public criminal law ( rape, incest, prostitution ) and with religious law ( Institution of Marriage ). In fact human beings can legally acknowledge human physical relations with any type of law if human beings are willing to acknowledge it. For example, State public civil law, i.e., the State Institution of Marriage. Same sex marriage advocates claim that since the Church's Institution of Marriage legally acknowledges human physical relations with Church law this means that , due to Seperation of Church and State, it is absolutely impossible for the State's Institution of Marriage to legally acknowledge human physical relations. The three s's of political correctness slick, subtle, and sneaky.
