Shelby Spong, as Bishop Pike before him, is widely criticized criticised even among liberals within TEC. He in no way reflects the mainstream. Most clergy I know see him as an embarrassment. However, I do see him as having value in that he opened-up discussion, and served as a counter-point for apologist. I have no doubt that the vast majority of the clergy of TEC believe in the Creedal basics of Christianity.
However, I also believe that those basics tenets have been distorted by modernity, and an impulse by many within TEC to appear ‘open minded’ in the face of modernity’s assault on Christianity. I am reminded of a saying I heard long ago, “I can be so open minded that all my brains fall out,” and another, “If you don’t stand for something, you can fall for anything.”
Many mainstream Protestants are, rightly, appalled by the shocking intolerance of fundamentalists. In an attempt to demonstrate TEC’s rejection of what often amounts to truly hateful pronouncements by some Protestant denominations, many in TEC over-reacted, and made extreme pronouncements of their own. This was especially true on sexuality.
The college campuses of the past 50-60 years have been quite hostile to religious views in general. Most of the current leadership of the church came of age in the 1960’s and '70’s and reflect the anti-religious ethos of the time.
