Bishop Tod Brown of Orange asked a group of diocesan advisers July 6 to "explore possibilities" regarding the Crystal Cathedral, once the home church of the Rev. Robert Schuller, a noted TV preacher.
The cathedral complex was put up for auction earlier this year as part of the cathedral ministries bankruptcy proceedings.
The organization founded by Schuller, now retired, filed for bankruptcy last October.
It was facing debt amounting to more than US$50 million.
The 3,000-seat Crystal Cathedral opened in 1970.
The Orange Diocese does not now have a cathedral to serve its 1.2 million Catholics.
