It's hard for people who are highly ideological to understand this, but most people and most human interactions are not all that heavily ideological. Churches and other affiliations depend more on social interaction, not ideology. Churches, especially, may have creeds that don't make a whole lot of sense even to the members of the church, but they accept the creed as "tradition" and often don't take the creed very seriously - because, for them, the creed or ideology just doesn't mean very much. They belong to a church or other group where they feel comfortable and at home, where they may have relationships and traditions and family histories that last for generations. And the warmth and length of those relationships, is far more important to them than any creed.

I'm a Catholic - with a seminary degree in Theology, and it took me a long time to realize that most Catholics have very little concept of Catholic doctrine. It's just not important to them. But the Catholic Church is rich in folklore and tradition and colorful rituals - and that's what is important to them. They may be very loyal to the Pope because the Pope is a treasured and colorful part of their tradition, but they have very little idea about what the Pope says and thinks and does - that is why Pope Francis is having such a hard time bringing about much-needed changes in the Catholic Church.

Most people don't have a world vision, or even a national vision - and maybe it's a good thing they don't.
