I’m not an expert in canon code, but there are actually canon code lawyers, aren’t there? That shows how complex it is.
What brings this up is my different experiences at weddings recently. The Catholic wedding, where the bride and groom both had to go through complicated annulment proceedings, where many of the guests were confused and bored by the wedding Mass, had to be step by step instructed on what to do. Approaching the Catholic Church is intimidating for our Christian brethren.
The other wedding was just as reverent, much more comfortable for all concerned. The Protestants seem to have managed to make their faith simpler and more approachable. They don’t need to have a complex canon code requiring lawyers. The more conservative churches teach basically the same moral code as the Catholic Church with the visible results being that the people seem just as holy.
My teenage daughter says that she thinks that generally Christians (she meant non-Catholics) are more into their religion than Catholics. She sees them as being more on fire for God. It does seem to me that many people in my church are satisfied with fulfilling their duties on Sunday and that’s it. They don’t talk about God during the week like some of my other Christian friends.
