I have been thinking through ways to paint various traditions in broad, but accurate, strokes. And I wanted to throw this out there and see if it sticks. If you are a member of the traditions I am representing, and feel that I am misrepresenting your tradition please let me know. This is not meant to be an argument, but an observation.
Protestants can be divided into two basic groups. I realize that there are probably people who fall under the description of either of these groups that wouldn’t necessarily consider themselves part of the group, but as is the case in any categorization schema, descriptive categorizations sometimes leave the nuances by the wayside.

Catholics can be divided into two basic groups. Within these groups there are of course more nuanced positions. Furthermore, it is possible that in some ways these groups are saying the same thing in different ways.
