I guess it's all where you get married. Many countries, Mexico for one, a church wedding (religious) is not legally binding. Only a judge (civil) can marry a couple, my daughter was married in Mexico and it was on the beach. It was beautiful, but it was done by the local magistrate. Therefore, if you are married in a religious wedding (church) in Mexico, it's not legally binding in the USA. I was married in Hawaii, on the island of Kauai, in the Fern Grotto... breathtaking. But since it was in the USA, we were married by a Pentecostal preacher (not my denomination) but that was who was available. So it's just between the couple and God, the rest is fluff.
