This is a challenging question. What do we mean being raised in the faith? I was not raised in traditional, liturgical Christianity: the sect (Pentecostalism) that I was raised in was so modern that when I ‘returned’ to Christianity, it felt as though I was discovering it for the first time. When I left Pentecostalism, I left Christianity and religion behind with it, and I was happy without them – at first. Eventually I realized a craving for something more, and I dabbled in ‘spirituality’ until finding a serious approach, that of Stoicism. It was Stoicism that opened my soul to God. After another season of life went by, I found myself feeling for the first time as though I were a sinner, and craved redemption. Recognizing this as a Christian feeling, when I decided to begin reassociating with religion, I started at a Christian church, albeit one theologically liberal (Episcopalian) enough for me to fit in, with my more or less unitarian belief. The passing of years, my desire to enter the Church more fully, has made me more orthodox in mind.
All that said, would I have felt a craving for redemption were I not raised in a Christian tradition? Possibly not, I cannot say. What I am sure of is that God would have called me to rest within him, regardless of my upbringing. It was God who called to me through Judaism, Gandhian philosophy, and Stoicism when I probed them (and in Stoicism’s case, became a practitioner). As Augustine wrote, we are made for God and our hearts are restless until they rest in him.
