In 1950 my late pastor, Msgr. Schuler, was in Rome on a Fulbright working on the manuscripts of Giovanni Maria Nanino, the successor of Palestrina for the Sistine Chapel. He had great stories about being a priest in Rome in that Holy Year and, specifically, of the Proclamation of the Dogma of the Assumption.
It was a different world. Think about it: the war had ended just 5 years before.
