For the second time this year, and for the third time since Summorum Pontificum came into effect (not counting private Masses), Mass according to the 1962 Missal will be offered by a bishop in St. Peter's Basilica.
His Eminence Darío Cardinal Castrillón Hoyos will offer the opening Mass -- a Messa Prelatizia -- for the General Assembly of the Fœderatio Internationalis Una Voce on the morning of Saturday, November 5, 2011. The Mass will be held in the Chapel of the Most Holy Sacrament of the Vatican Basilica.
The first publicly-offered TLM of a bishop in St. Peter's after the liturgical reform of Paul VI was held in the same chapel on October 18, 2009, with then-Archbishop Raymond Burke as celebrant. This was followed by the TLM of Walter Cardinal Brandmuller at the Altar of the Chair on May 15, 2011.
