This is something I've noticed as well . . . .and I've experianced it in my own life several times. Although I've spent yrs in most church's I've attended, I've changed denominations/church's several times (been called a church hopper

). It was hard to leave a couple of them on count of family and dear friends . . . .I would so love to be surrounded by my family in church.
I've never left a church in a huff or in bad standing . . .it's always been about sound doctrine. At some point tho I would discuss my reasons with the Pastors to explain myself and to hopefully be constructive.
It's important to me to be sure that I identify myself with Christ and the truth rather than with a denominations doctrine or even my family. It's a tricky little thing our will and our situation will do to convince us that wrong is right.
Even now, although my church is 95% satisfactory to me, the folks are the best I've ever seen in a church, the teaching is great, and I'm almost totally in agreement with it all . . . .but if the Lord leads me to another fellowship I'm gone.
Jer 2:11 Hath a nation changed their gods, which are yet no gods? but my people have changed their glory for that which doth not profit.
Jer 2:12 Be astonished, O ye heavens, at this, and be horribly afraid, be ye very desolate, saith the LORD.
Jer 2:13 For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water.
