I am Catholic and have grown up my whole life attending Mass. When I was young, I was very bored, and found the set prayers of the priest and the congregation to be monotonous. I also didn't know why we were doing what we were doing. Now, as I understand a lot more, I have grown to appreciate it. However, I understand from conversations with others, that for some, praying to God in nature is enough for them. My question is: should there be a set structure in worship at all (predetermined by someone else)?
