The elder Schuller put his son, Robert A. Schuller, in charge of his ministry in January 2006. That included the Crystal Cathedral and the syndicated "Hour of Power."

In a statement read by Jim Coleman, president of the Crystal Cathedral in Garden Grove, Calif., the elder Schuller said he was seeking guest preachers for the program. In recent weeks, the show has consisted of reruns of the father.

"No longer will the 'Hour of Power' be the voice and face of just one or two individuals," Robert H. Schuller said. Without being specific, he said he and his son had "different ideas" on the direction of the ministry.

The younger Schuller remains a senior pastor at the Crystal Cathedral.
