Looking up into the modern “rafters” of St. Mary’s Cathedral 50 years after it was dedicated, San Francisco Archbishop Salvatore J. Cordileone marveled at the structure designed and constructed by chance in the years following the meeting of the Second Vatican Council from 1962-65. “It’s bold, it’s imaginative and it perfectly expresses what the Church has been discerning for a long time now, since the world moved into this modern era,” the archbishop said.
