Same Sex Marriages

After the Supreme Court's recent ruling, I am assuming that the Church is going to change its position on same sex marriages, is that correct?

There is a simple answer for that - no, never.

The longer answer is that the Church will never allow same-sex weddings — because we believe that marriage is a sacrament, and we can’t change the content of the sacrament. A sacramental marriage is between one man and one woman for life, and we can’t change it any more than the Church can declare that a triangle is round or a square has three sides.

The essence of marriage between a man and a woman was established from the beginning of the human race and validated by Jesus Christ and established as a sacrament for our salvation. Marraige between one man and one woman as the norm has existed in societies for thousands of years, before the establishment of any formal religions. It exists this way because God established it as part of the natural law.
Just as we do not allow same-sex weddings, we also do not allow plural marriages or marriages between closely related persons (e.g. siblings) for the same reason.
