The following comes from an Orange County Catholic article:

At 55 years old and counting, the Garden Grove parish formerly known as St. Callistus is experiencing a rebirth.

The parish, founded in 1961 with its first Mass celebrated in a roller rink, has been transformed into Christ Cathedral Parish.

As the Mother Church of the Roman Catholic Diocese of Orange — the bishop’s Church — Christ Cathedral Parish is host to major diocesan and Church gatherings, and will be where ordinations to the priesthood and diaconate are celebrated.

The Rite of Election for all those in the diocese preparing for initiation into the Church also will be held at Christ Cathedral Parish, as well as special Masses such as the Chrism Mass and the Red Mass, the annual Mass for Catholic judges, attorneys, law school professors, students, and government officials.

That’s quite a change for longtime St. Callistus parishioners.

But most view the transformation as an opportunity to further strengthen one of Orange County’s most diverse parishes, which offers 12 weekend Masses in English, Spanish and Vietnamese, with an average attendance of 10,000 across all services. In addition, the Chinese Catholic Association rents space to hold a Mass in Chinese.

“The transformation of St. Callistus to Christ Cathedral Parish has been exciting, renewing and challenging — like a new beginning,” says Mary Lynn Vargas, co-chair of the Christ Cathedral Community Outreach Ministry and a parishioner of St. Callistus/Christ Cathedral Parish for 37 years.

Such a dramatic change for a parish — whose original members still are called “holy rollers,” a reference to the roller rink — hasn’t been without its challenges, of course. But that’s natural, says Fr. Christopher Smith, rector of the Christ Cathedral.

“This parish not only changed its identity, but literally moved,” Father Christopher says. “And the change is more than geographic. The identity of a cathedral parish is distinct…It takes time for people to not only accept that, but to understand it and take it on.”
