The Holy Father again celebrated the Mass ad orientem for the Feast of the Baptism of the Lord. This was held in the Sistine Chapel. The fact that he has been doing this for the past three years should prove the point that the Mass in the ordinary form (according to the Missal of Paul VI) may be legitimately celebrated ad orientem. It seems that many bishops and liturgists do not understand this point.
Thanks to New Liturgical Movement for the pictures.
