With a little research, I discovered that the Tridentine Mass at the University of Southern California this past Sunday was NOT the first. There was another held May 3, 2014. There is an old Facebook page and also a YouTube video of the entire Mass. The video states that the Mass was "student initiated" and assisted by various Latin Mass organizations in California. The music was performed by USC music students and was absolutely first rate!
There is an interesting page on the Our Savior Parish/Caruso Catholic Center's website, which explains the Catholic history at USC. A history which seems to have come full-circle. It states that USC possesses "one of the most influential Catholic constituencies in the country." USC is taking the lead in bringing back Catholic tradition in a bold and surprising way. Catholic universities: are you listening?
