My father was an Assemblies of God pastor, so I grew up AoG. I attended Southeastern University (an AoG school) and while there attended WoF/Charismatic/NonDemon churches (mostly WoF) as well as studying under a Messianic (formerly Chassidic) rabbi--eventually doing quite a bit of teaching myself in the area of the Jewish Roots of Christianity (had a radio program, etc.), writing a Haggadah, etc.
As I moved into my grad work, I kept running into certain discrepancies between what would have been seen in the earliest days of the Church (when the believers still met in synagogues, etc.) and "modern" Christianity. During this time, I kept feeling God drawing me toward the historic churches. I began to wrestle with the issue of apostolic succession-- I mean, who really gives someone the authority to "ordain" others for ministry? I saw what actually occurred in scripture (Acts, specifically) and had to ask myself if anyone was actually doing things they way they were done there? I also could see and understand the Jewish liturgies-- the symbolism, etc. contained with them... yet the average Charismatic worship service looked nothing like that. Eventually, I found a copy of the Quorbana-- one of the oldest known Christian liturgies from the Middle East. For me, it was the "missing link", as it was an early eucharistic liturgy-- still partially in Hebrew, even including the Sh'ma.
So, now I realized that I could either accept what I saw to be true in both Scripture and Church history... or I could try to ignore it and stay where I was (I was actually on staff at a mega-church at the time). I began to search the different historic churches... to see where I could fit. The Orthodox churches were just to ethnic for me (I'm a white boy from south Georgia) and I couldn't see myself fitting with Russia, Greek, etc. culture. I could not agree with Papal Infallibility, as that was not a dogma (even in the RC) until the 1870's. I seriously looked at the Episcopal Church, but some of the issues that were just starting to really come to the surface at that time (think Gene Robinson) made it clear that the Episcopals were heading a direction I did not want to go. I repeatedly tried to make contact with the Charismatic Episcopal Church (which actually have OC lines of apostolic succession) and each attempt just came to nought. Somehow along the way I stumbled across the OC's. I began to do some research, and found that they were almost a "hybrid" of the RC's, the EO's, and the Anglicans. They are more 'open', in that sacraments are available for all baptized Christians (like the Anglicans)... they are western in culture (like the RC's)... and they are more open to "mystical" experiences (gifts of the Spirit) like the EO's. It was just the right fit.
And the rest is history...
