Get Married in Gods Eyes and Not Legally?

There is a Christian church that does not believe in legal marriages. They say to legally wed is to make your marriage the product of the state. Tim LaFollette has ALS and he and his wife Kaylan had a non-legal ceremony because he would lose his insurance if he were to legally marry her. They have a YouTube channel and a documentary series called Often Awesome. Really, it's up to you and your conscience.
