On Wednesday, April 21, 2010, the Rt. Rev. John Shelby presented a lecture at Trinity Cathedral in Cleveland. Bishop Spong, whose books have sold more than a million copies, was the Bishop of the Episcopal Diocese of Newark for 24 years before his retirement in 2001. Now Bishop Spong, a leading Christian liberal and activist, has written a new spiritual autobiography, Eternal Life: A New Vision. In Eternal Life, he goes beyond religion and Christianity to an understanding that the fully realized human life empties into and participates in the eternity of God.
