This question from Bruce Epperly, Director of Continuing Education and Professor of Practical Theology at Lancaster Theological Seminary, is contained in the blog entry "Spirit-Centred Progressives?" (click here) at the Transforming Theology: Rekindling Theological Reflection website.
Epperly writes: I believe that spirit-centered progressivism will inspire new experiences of the wholly/holy and reach out those who calls themselves “spiritual but not religious.” As progressives, we no longer need to live by our denial of outmoded theologies or the opposition of the horizontal and vertical dimensions of life; rather, we can claim a deeper naturalism in which the vertical reflects the ubiquity of God’s presence in every moment of experience. In so doing, we can claim a variety of “naturalistic” spiritual practices and experiences as reflective of God’s intimate presence in Jesus of Nazareth and our own lives. We can create 21st century progressive spiritual practices, congruent with the positive and constructive insights of progressive theology. In so doing, progressive Christianity can respond creatively to 21st century mystics, seekers, and persons who describe themselves as “spiritual but not religious.
Epperly's interesting book, "Holy Adventure: 41 Days of Audacious Living" is available at the PCNV bookstore (click here for details).
