Welcome to the forum!
I was born and raised in the former Soviet Union, and I was never baptized at all as a child. My whole upbringing and education was completely non-religious and, at times, anti-Theist. However, my home city, the capital of Ukraine, Kyiv ("Kiev," Russian pronounciation) has always been a citadel of Holy Orthodoxy; so, from my early childhood on, I have heard church bells, seen beautiful icons and murals in Kyiv churches, and heard the breathtaking sound of the choirs at the St. Volodymyr Cathedral, the church that happened to stand in just a few blocks away from my parents' apartment. That planted some seed in me.
When I came to the USA in 1990, being already in my 30-s, I wandered for a while, and, in late 2002, bumped into a Presbyterian congregation, and was baptized there. At first, I enjoyed the Bible studies with my parish members, and was impressed by what, back then, looked to me like a logically perfect "system" of Calvinism. Yet, in just a few years, I was utterly disappointed by the, how should I better put it, dryness, "left brain-ness," hyper-rationalism of what Calvinists tried to deduce from Scriptures. And I, most of all, sensed a lack of what I had experienced back home, during my occasional (and sometimes secretive) visits to Kyiv churches: the CHURCH. In an Orthodox parish, any parish, no matter what else, I sensed what a Protestant theologian called Paul Tillich used to call "the feeling of the immediate presense of the Holy." In my Presbyterian congregation, and, for that matter, anywhere except in an Orthodox parish, I did not have that feeling, no matter how hard I tried to convince myself that "it was the right place." Even when I was elected a Presbyterian elder in 2004, I still did not develop that unique, undescribable feeling.
In October 2006, I severed my ties with the Presbyterian congregation, and soon found the Orthodox Church. I was finally received into the Church in February 2007, and I am, currently, a member of a Greek Orthodox mission parish in Aberdeen, MS (about 50 miles from where I live). Believe it or not, now, as I am studying Holy Orthodoxy, including some important works of the Holy Fathers of the early Church, I see that Calvin and his Western European followers were severely misguided and often utterly naive. I am a bad, weak Orthodox; I might misunderstand, and even sometimes rebel against, some Orthodox teachings; and yet, what I learned while being Orthodox is so much richer, more historically rooted, more comprehensively Christian and Apostolic than the attempts of the so-called "Reformers" to rationalize from Scriptures.
Whatever experience you have and will have, - my all best wishes to you, and may the Lord illumine your heart and your path to the Truth.
