What you experienced here is the shift from one social class, the working class with its limited understanding, stress on rules and obedience, and particular perspective on Christ. You further made the shift from faith in your family/community to a personal faith, hopefully in Christ of the creeds. This is not an easy shift, psychologically speaking.
Whole denominations, as well as congregations, have developed sharing this point of view. They are distrustful of outsiders and educated persons, and for good reason. Educated persons hold them in contempt. Furthermore, educated persons, like slick lawyers, and theologians who use their learning to rationalize their own sin by condemning others, exploit them. They often have unrealistic expectations of professionals, like doctors, and then these expectations are disappointed, leading those disappointed to deeper distrust.
Beware the same pride that led you to win the Bible contests can lead you to look with contempt rather than love at those who gave you your faith (those who God used for that purpose). A child’s faith must give way to a more mature understanding, as St. Paul said, “When I was a child, I reasoned like a child, but when I became a man, I put away childish ways.” Forgiving our fore- bearers their failings is part of that putting away childish things.
