I have a Jewish friend who was very close to Pope John Paul II and when he died her family was summoned to Rome, where her son read the Kaddish over the pope's remains in the papal chapel.
From Jewish World:
France bade farewell to Cardinal Jean-Marie Lustiger on Friday in a ceremony that mixed prayers from his Jewish roots with the rites of the Roman Catholic Church, a faith to which he converted during World War Two.
A cousin of the late archbishop of Paris, Arno Lustiger, read the Kaddish, the Jewish prayer for the dead said in Aramaic, the language Jesus spoke, at the start of the ceremony outside Notre Dame Cathedral in central Paris.
