Columbia Bible College and Seminary had its share of confessing Calvinists, but most were tainted with Arminianism to a greater or lesser degree. The church growth movement advocates made a vigorous and unrelenting effort to promote their agenda through the seminary. From all indications they were successful. I know why the church growth movement invaded the ranks of theological education, but I don't know how it happened so quickly. You will find an abundance of such courses available in conservative, fundamental, or Reformed seminaries.
Atheological education is fundamental to the chief advocates of the church growth movement.
The church growth movement is not entirely to blame for the widespread permeation of atheological education in seminaries. From the annals of Robert Schullers' self esteem psychology to group psychotherapy, many seminaries are in need of a recovery program to recover from recovery. Theological education at a seminary with Reformed standards is not without a multitude of problems. Postmodern thought significantly influences theological education. Revisionism and deconstruction hermeneutics have played a subtle role in the shift from confessional standards to broad evangelicalism and perhaps even an ecumenical spirit.
