Let me respond by telling you a story. I grew up in the Assemblies of God church. I was very devoted to it for a number of years, so much so that many things I observed troubled me. One of these was the fact that many of the people I grew up with were leaving the church. I talked with one of the pastors about it, who was completely unconcerned. He told me there was no problem because the church was growing. I replied that having more people is not equitable to having people who are devoted to the church. As I was praying about this situation, it became clear to me that the church had serious theological flaws, and that this was the primary reason for my friends' unhappiness. I was faced with the decision to stay and try to remedy these flaws, or to leave. I chose to leave.
I didn't know where to go, so I tried a Southern Baptist church down the road. I, too, made a profession of faith, in the Baptist doctrine, which at the time I felt was more accurate than the Assemblies'. During this time, I kept many of the friends I had in the Assemblies church. Occasionally I would go back to the church, but I never felt at home there anymore.
Finally, through research into the life and practice of the early Christians in the book of Acts, I became convinced that neither the Baptists nor the Assemblies of God believed like the early Church. I never doubted, however, the truth that God would preserve his Church. Rather than becoming disillusioned, I left the Baptist church in search of true Christianity.
It was at this time that I was invited to the Orthodox parish by a friend I had met in college. Immediately upon entering the building I knew that, although the Church appeared to my senses different than I expected her to, to my spirit she was the Church I had been reading about and searching for.
After my conversion, I attempted to keep the friends I had had for several years now, but it proved to be impossible. As I began splitting my time between them and the friends I was getting to know at the Orthodox parish, I found myself drifting from them. Eventually, they chose to end the relationship (unkindly, too--I found myself at the wrong end of a fistfight).
I say this not to scare you, but as you come into the Church, you may have to make sacrifices. For me it was friends I had known since junior high school (as well as having to flee for my life to another apartment, changing phone numbers, etc.). Remember, to "know Him and the power of his resurrection" is to be in "the fellowship of his sufferings, being conformed to his death" (Philippians 3:10). What form that death must take God will reveal to you. This message board may, and I stress may, be something you have to give up. Whatever you should do, it will be made plain to you as you pray and continue on your quest to become like Christ.
