About 85% of people say they have a religious faith of some kind. That gives us a lot in common. But when it comes to folding beliefs of faith into the daily choices and decisions in marriage, it seems people lose sight of the differences and it seems like they are the same. There is no doubt that both types of marriages are perfectly fine, and everyone should be entitled to pick how they want to structure theirs.
Having a traditional Christian marriage does require more of the participants in that marriage compared to a civil union or legal bond. As you look for ways to change or improve your relationship, it might be a good idea to keep you of those differences in mind, and the requirements required if you choose that path.
One of my favorite descriptions of a Christian marriage comes from C. S. Lewis, a famous writer, and an excerpt from his book “Mere Christianity” is quite good at outlining the differences.
