There's been some confusion between this article (previously named "Roman Catholicism") and the Catholicism topic. Part of the confusion was that the old title made it sound like a religion (ended with "ism"), but in fact the topic is really about the Roman Catholic Church as an organization. This resulted in the topic being typed both "religion" and "religious organization", which is almost never going to be appropriate - the data model makes a distinction between a religion (a set of beliefs, practices, and rituals adhered to by a group of individuals) and a religious organization (an administrative body associated with a particular religion).
To correct this, I renamed this topic to "Roman Catholic Church" (bringing it in sync with its id) and removed the "religion" type. Any topics that were pointing to this topic as a "religion" topic have been edited to point to the Catholicism topic instead. I hope this will makes things clearer going forward.
