A public memorial is underway for televangelist Rev. Robert H. Schuller outside the glimmering cathedral he built in Southern California.

Schuller died on April 2 after a battle with esophageal cancer. He was 88.

The service is being held Monday on the campus of what was formerly Schuller's Crystal Cathedral in the heart of Orange County and is now Christ Cathedral of the local Roman Catholic diocese. A private burial will follow.

Schuller started preaching from the roof of a concession stand at a drive-in movie theater in 1955.

He began the televised "Hour of Power" in 1970 to spread his upbeat messages on faith and redemption -- that "possibility thinking" and love of God overcome hardships.
