Stepanov,
I would urge you to read "Against False Union" too.
You want to know what to do, well, St. Cosmas said that in the last days one would have to travel three days and three nights to get to a true Church. It sure seems as though he were referring to these days. So when you reach the GOA church you mentioned, pick-up the pace and keep going right past it. And may the Lord have mercy on us all.
I don't know about anyone else, but I thank the Lord in heaven His church is only 40 miles from me, in that I was not choked to spiritual death in all my years in the GOA/OCA. But my journey to get there was not just about distance, it was much more about searching for the truth. And coming to realize everything I have found, the distance is nothing. I would move across the country or the world in a second to be in a true church.
If you are learning about Orthodoxy, don't listen to me or anyone - because the only people you can trust are the Holy Fathers. Read what they have to say and then you will learn who to trust.
