This question involves a few intertwined issues, but generally the question is: is it normal for Christians to switch denominations? Or is it considered "flaky"? For example, my parents went to a Baptist Church but when we moved we started going to an Episcopal Church (I think there was no Baptist Church within a reasonable driving distance). It gets more complicated when you are Baptist not by affiliation with a particular group of people but in only that you believe in baptism by choice (believer's baptism); there seem to be, in fact, Episcopal Baptists. That aside, assume my parents went to a church of a denomination clearly distinct from their later choice of Episcopalian. Do most Christian's consider the move "unfaithful" in some way? Or is it normal for Christian's to jump around from one to another at their convenience?
I ask only because I was reviewing a question I asked and I noticed Mr. Stratton say that he "currently belongs to" XYZ Church. I thought it interesting to word it that way; as if one may change their mind from time to time.
If I were to venture a guess, I'd say that people who go to Church out of convenience or more habit (like my parents) will change their Church whenever it is convenient for them. They just go to Church so they can feel good at night, it's like a weekly community service to them. However, those who go to Church for the experience and atmosphere and actually care about the views of the people will tend to only join Churches which share their views on various topics (abortion, gay marriage, etc.). But maybe there are more factors that I'm not aware of, having not been to Church too many times in my life.
