As the Dean of the College of Cardinals, Joseph Ratzinger determined the specifics of the funeral Mass for Pope JPII and the Mass pro Eligendo Summo Pontifice during the interregnum. They were both very reverent, spiritual and beautiful. The latter was almost entirely in Latin with the Mass of the Angels (Missa de Angelis) ordinary. His wonderful homily was given in Italian (which is very close to ecclesiastical Latin).
I hope that he will be more actively supportive of Catholics who are attached to the Tridentine rite than JPII was.
