Ana and established Christ Our Savior Cathedral Parish, with the intention of someday building a cathedral on the property. The cost of building a cathedral on the Santa Ana site was estimated to be as high as $200 million, which prompted comparisons to the cost of building the Cathedral of Our Lady of the Angels in Los Angeles. In October 2010, Crystal Cathedral Ministries, the Protestant congregation that owned and worshiped in the eponymous Crystal Cathedral building in Garden Grove, filed for bankruptcy protection. Several months later, the diocese announced that it was "potentially interested" in buying the building and converting it into a diocesan cathedral as a potential cost and time-saving alternative over building a new cathedral on the Santa Ana site. On November 17, 2011, a U.S. bankruptcy court judge in Santa Ana approved the sale of the Crystal Cathedral building and adjacent campus to the diocese for $57.5 million; the sale was finalized on February 3, 2012. At that time, the diocese ended all efforts at building a cathedral on the Santa Ana site and removed "Cathedral" from Christ Our Savior Parish's name, repurposing it as a diocesan parish church. On June 9, 2012, the diocese announced that the Crystal Cathedral would be known as "Christ Cathedral" when it becomes the new seat of the diocese. The building's new name was designated by the Holy See, while suggestions were also taken from the diocese and its members. In 2014, following its purchase of the site, the diocese announced plans to renovate the Crystal Cathedral in order to suit the liturgy of the Catholic Church, while maintaining the building's architectural qualities. Construction for the $72 million project began in June 2017, and was completed in 2019. In June 2013, the diocese officially transferred St. Callistus Parish to the Crystal Cathedral campus, and the parish began to hold Mass on the campus. At the same time Crystal Cathedral Ministries moved to St. Callistus' former facility, located one mile from the Crystal Cathedral, which the diocese offered to lease to Crystal Cathedral Ministries as a term of the sale of the Crystal Cathedral campus. St. Callistus' parish school was transferred to the former Crystal Cathedral Academy facility and renamed Christ Cathedral Academy in September 2013.
