Hidden uncertainty

As it has been a few years now that I have stepped out of Protestantism, something has been coming clear to me.  As a Protestant, the choice of doctrine and practice was mine to make.  And I did make that choice multiple times over the years.  As an avid reader, and lover of study, the more I read, the broader my understanding base became.  Essentially it came to the point where I realized that anything I wanted to believe, I could justify by the manipulation of Scripture and logic and I could find a community that believed and practiced the same thing.
This is what every denomination, parachurch organization and quasi- Christian cult does.  This is the whole problem with Protestantism/evangelicalism. 
Looking back over the years as a Protestant, I wonder how I wasn't more apprehensive about the whole thing.  I guess I couldn't see the problem from the inside.  Now, as Orthodox, the thought of not having a legitimate authority over me and my family is frightening.  This is not cowardice or mindlessness, this is common sense.  One would not travel through the Amazon jungle without a guide and this world is far more dangerous than any jungle. God has given us the Holy Spirit led body of Christ (the historic church).  It is sheer lunacy to reject that authority and wing it alone.
Of course, the Protestant response is, "I have the Holy Spirit leading me."  While this sounds holy and pious, it's arrogance.  To claim that the Holy Spirit is leading your church and no other, is ridiculous.  There is no historical footing upon which to stand.  And even beside that, every single denomination, parachurch organization and quasi Christian cult makes the same claim, and they can't all be right.
Unless one wants to claim that doctrine and practice doesn't really matter, the present state of the Protestant world is untenable.
What is historically true is the fact that the Holy Spirit is leading the Orthodox church.  Herein is found the body of Christ and communion with God.  There is no need to look anywhere else.  All the answers are here.
