Is this a serious comment and question, or do you really not know?

God and His Word are eternal, and opposite-sex marriages are not a cultural construction of the Judeo-Christian religion.

There isn't one example of same-sex marriage in the Bible, nor any support for such uNIONS that isn't absolutely scathing.

There are; however, a multitude of opposite sex marriages mentioned and detailed.  The first is Adam and Eve.  Remember now?
