This Practice is Long-Standing

10. We have Ourselves dealt with the commemoration of the Roman pontiff in the sacrifice of the Mass, and with the antiquity of this practice in Our treatise De Sacrificio Missae, sect. I, n. 219. But since the publication of this book, the same subject has been treated with many extraordinary observations by Dominicus Georgius (who in his lifetime was Our dear sacristan) in his De Liturgia Romani Pontificis, vol. 3, chap. 3, no. 14, where he writes: "It has ever been customary in the Catholic Church to recite the name of the Roman pontiff during the sacred mysteries." In no. 22 he adds: "All the ancient testimonies and the oldest copies of the sacred canon agree concerning the name of the supreme pontiff." Indeed, that such a commemoration had been made in the Mass is shown by the Ambrosian Liturgy, the Mozarabic Mass, and the Latin Mass which the Lutheran Flaccus Illyricus copied from one ancient manuscript and published. So also does the most ancient Liturgy which is found in the old manuscript on the Sacraments of the Roman Church which was published by Venerable Cardinal Thomasius. Finally, this is also shown in all the sacred canons of the Mass, whether printed or written by hand, as the prelate Niccolo Antonelli amply shows in the long and learned dissertation which he wrote as a necessary part of his duty as Secretary of the Congregation for the Correction of the Euchologion; he had it printed when a dispute on this subject arose among the Cardinals and Consultors. A reprint of this can also be I found in the Appendix to the old Lateran Monastic Missal in the Collectio Liturgica, vol. 1, made by Fr. Emanuele de Azevedo.
