Agnus Dei from Mozart's Coronation Mass; St. John Paul II, Herbert von Karajan and Kathleen Battle

Yesterday we discussed Mozart's assertion that Protestant Christians did not understand the Agnus Dei qui tollis peccata mundi [here].  Whether he was right about that or not, Mozart himself did indeed understand, as is clear from the magnificent Agnus Dei from his Coronation Mass. This is from St. Peter's Basilica in 1985: Saint John Paul II is saying Mass, Herbert von Karajan is conducting the Vienna Philharmonic and Kathleen Battle is the Soprano.
