On this question I suggest that what is needed is less attention to theology and more attention to such things as Christian Karaoke. I know a dozen or so people who have made the pilgrimage from evangelicalism to Orthodoxy, Roman Catholicism, Lutheranism, or Anglicanism. All are thoughtful people, and theology is important to them. But in each case their initial decision to migrate had little to do with a rejection of evangelical theology. Rather, they left evangelical churches out of despair over evangelical culture.
All churches have an order of service.
Some are more rigid, dry, and man-centered than others. That is why some are leaving evangelicalism. They find the ancient liturgies of the older church traditions to be more flexible, expressive, scriptural, and focused on the adoration of God than the stripped-down liturgies they encountered in evangelical churches, or the standardized pep rallies of charistmatics. It bathes every activity of my day in prayer, and gives me a language for expressing my thoughts to God that I never could have come up with on my own. Father, we just want to praise you, Father.
