The AP article actually quotes a traditionalist. He is Duncan Stroik, a professor of architecture at Notre Dame who specializes in cathedrals. He says, “The concern always is that while it [a current cathedral] maybe seems very innovative at the time, that it goes out of date very quickly."
Here is another excerpt from the AP story:
"Stroik, who favors a traditionalist approach, also questioned whether the artistic goals of modernist cathedrals, often designed by architects renowned for their secular work, overshadow the spiritual.
“'It should be a work of faith, and it should express eternal verities,' he said. 'If the architect doesn't believe those things ... is it possible for him to express those things?'”
In the AP article, Bishop Allen Vigneron of Oakland says the cathedral's planning was done with a "liturgical consultant." He says, “The cathedral is an occasion and catalyst for the rededication of Catholics of the East Bay."
The AP story continues: "Diocese officials favored the 21st-century aesthetic to mark the cathedral's place in time and culture, and show that 'we are not an antique or a relic of yesteryear,' Vigneron said."
