LOS ANGELES — The aging founder of the Crystal Cathedral has gone to court seeking more than $5 million from the ministry he built from scratch in a dispute that has delayed millions in payments to creditors left short-handed when the church filed for bankruptcy two years ago.

The Rev. Robert H. Schuller was in Los Angeles on Thursday for the start of a 10-day trial over copyright infringement, intellectual property, and contract violation allegations that stem from his ministry’s devastating financial collapse. The trial continued Friday with testimony expected from his wife, daughter, and son-in-law.
