I believe that John Corapi's conversion, becoming a priest, and initial efforts to save souls were, in the beginning, entirely sincere. Somewhere along the way, his ministry became a business to him, and he reveled in excess - once again dazzled by worldly rewards as in his previous career as a millionaire. Contrast the humble priest in his early priesthood with the dyed-beard guy who ranted and raved for the money.
Perhaps he has once again hit bottom and is crying out for Our Lord and Savior. If so, may God grant him peace and good health as well as forgiveness.
