I was just out to lunch with a priest friend and also Orbis Catholicus – Mr. John Sonnen, who always posts fun photos from Rome and environs.
Orbis got a phone call during our post-lunch coffee and… well… I am posting it first, but you should go to his blog for details.
It seems that Card. Castrillon Hoyos on 8 October with pontificate with the Extraordinary Use in the Borgehese Chapel of the Basilica of St. Mary Major in honor of Pope Pius XII. If I understood correctly, the FSSP will be seeing to the ceremonies.
You will be sure to go visit Orbis for the details.
I also want you to remember that John Sonnen works a bit as a tour guide. He knows Rome well and is very Catholic on the traditional side of things.
