I know that the Episcopal Church and Anglicanism are not the only groups in the midst of controversy, competition, in-fighting, and the like. Most American mainline denominations are pulling themselves apart to one degree or another, not just the Episcopalians. The fight in many of the more conservative or Evangelical churches tend to be around the resulting different emphases and methods between Modernists and Post-modernists.
A couple decades ago, the “conservatives” in the Southern Baptist Convention gained control of the denomination and proceeded to purge the seminaries, colleges, churches, missionaries, and leadership of theological and social “moderates” and especially “liberals.” They succeeded. The Southern Baptists truly become a Fundamentalist denomination, and proudly so. There are groups within the mainline denominations that are trying to do the same kind of thing, although probably not to lead the Churches to Fundamentalism, but at least American-Evangelicalism – back to the “real Faith.”
This is the thing about those who believe that they stand up for and live out the “faith as it has always been” from the very beginning, free of cultural influences and capitulation – the reality is that none of us do! The truth is, and this is the Truth-on-the-Ground, is that few understand what culture does to us and few take the time to learn about how the Church’s understanding of God, its interpretation of Scripture, its sense of how to live godly lives has changed radically! A survey of history will make this assertion obvious. This does not mean that the essence of the faith is any different – God came to us to free us from sin and death and to re-enable relationship and reconciliation between God and Man and between one another.
All that to say that even within the Southern Baptist Convention, which experienced decline in membership and baptisms last year (which should be no surprise, because social-Christianity continues to decline in the U.S.), there are still fights and challenges to what the Faith is and means and how to best live it out. They are certainly not where the Episcopal Church is at, but it is only by degree and time span.
Here is an article entitled, “Young Baptist preachers chart different courses,” about the changes within the Southern Baptist expression of the Faith and controversy that results.
