Gordon Cosby, the prophetic founder of the Church of the Savior, passed away yesterday. I interviewed Cosby in the fall of 2009 in the library of the Festival Center, one of the many buildings in the Adams Morgan neighborhood of Washington D.C. where the (un)church that Cosby founded in the 1950s has thrived.

In our interview, Cosby—at 91 dynamic and impassioned—talked about how ministries have an “essence.” The essence of a ministry, he said, is how it participates in the “breaking through of the Kingdom of God.”

But all too often, a ministry loses its essence. It begins to exist for itself and to lose its sense of ultimate purpose. It does a job, instead of listening for the heartbeat of the Holy Spirit. Growth, success, vision, organizational and individual ego all serve as obstacles to essence. All of them, he felt, were very much an issue in the contemporary church.
