It just means a religion with a formal structure and leadership behind it. The term points to the institution and its influence, not the beliefs themselves. An unorganized religion is basically personal or informal practice without a central authority, like an individual or essentially a book club.

Right, but I don't know what is referred to by "practice" that is at all distinct from "worldview" or "ideology".

This is my informal understanding; I am not a religious scholar
