I have actually never left a church because of doctrinal differences. But if I do disagree with what they are teaching I should go to the leaders and sit down and discuss why I believe what I do and vice versa and then we take it to the bible and which ever one of us is proven wrong by the Scriptures must then submit to what the Word of God says. That is how it should work, sadly you are right though people just leave,just like it is way to easy to get a divorce.
But no where in the bible does it say to take it to the bible if there is a disagreement.
15 But if thy brother shall offend against
thee, go, and rebuke him between thee
and him alone. If he shall hear thee, thou
shalt gain thy brother.
16 And if he will not hear thee, take with
thee one or two more: that in the mouth
of two or three witnesses every word
may stand.
17
And if he will not hear them: tell
the church. And if he will not
hear the church, let him be to thee
as the heathen and publican.
18 Amen I say to you, whatsoever you
shall bind upon earth, shall be bound also
in heaven; and whatsoever you shall loose
upon earth, shall be loosed also in heaven.
Mt 18:15-18
No where in the bible does it say that the Bible is the first, last and only authority. No where in the bible does it say that the bible alone is the teacher.
15 But if I tarry long, that thou mayest
know how thou oughtest to behave
thyself in the house of God, which is
the
church of the living God, the **
pillar** and
ground of the truth.
1 Tm 3:15
15 "The pillar and ground of the truth"…
Therefore the church of the living God
can never uphold error, nor bring in
corruptions, superstition, or idolatry.
If I ever disagreed (which I haven’t) with the Pope on a certain doctrine, I would never go to the Pope and say, “hey look you have this wrong when it comes to this particular scripture.”

Huh?! I would never do that. I would just have to accept the teaching, obey what the Church says and then go and study scripture if I wanted to, so that I can see if I could understand why the Church teaches a certain thing in a certain way.
What if you go to your minister and challenged him and he still did not agree with what you believe is right? Would you leave that church? Or would you submit to them out of obedience? But who are you obeying? Do they have the Authority directly from God who gave His authority to Jesus who gave His authority to the Apostles who in turn passed it on to their successors who are our Bishops with the Bishop of Bishops being the Pope? I certainly have to obey my prelates just as it says in Scripture.
16 And do not forget to
do good, and
to impart;
for by such sacrifices
God’s favour is obtained.
17
Obey your prelates, and
be
subject to them. For
they watch as
being to render an account of your
souls; that they may do this with joy,
and not with grief. For this is not
expedient for you.
Heb 13:16-17 (DR-V)
