The Pontifical Commission Ecclesia Dei, which was recently incorporated into the Congregation for the Doctrine of the Faith, has announced the publication of two DVDs to help “priests and the community” celebrate Mass according to the extraordinary form of the Latin Rite. The two DVDs include an entire Mass celebrated by Cardinal Dario Castrillon Hoyos-until recently the president of the Commission-at the Basilica of St. Mary Major in 2003. The discs also feature segments explaining in detail the “gestures and rubrics, from the preparatio ad missam (preparation before Mass) to the act of thanksgiving in the sacristy.”
