Crystal Cathedral

... the story of Christ Cathedral is deeply ecumenical, just like American Catholicism generally.

The U.S is traditionally a Protestant, even Calvinist, culture, and as a result, Catholics have been compelled to make their peace with the Christian “other” from the very beginning. It’s no accident that the Week of Prayer for Christian Unity, now a global observance, began in the U.S. in 1908 with the Graymoor Friars, led by a Catholic convert from the Episcopal Church.

Christ Cathedral is not only ecumenical in the sense that it was built by a Protestant preacher and televangelist, architecturally reflecting a Protestant sensibility, but also because there’s a graveyard on the grounds containing the remains of members of Schuller’s congregation.

Called “Cathedral Memorial Gardens,” it becomes the fourth active cemetery within the Diocese of Orange and the only one that’s ecumenical. (It’s actually rare these days to have an operating cemetery adjacent to a church, though it was once the norm.)

Deliberately, the cemetery is open to Catholics and non-Catholics alike, reflecting the multi-denomination ethos and history of the site.
