20. Still in reference to the Latin practice, We will also note that when a bishop is celebrating Mass, he prays for himself as an "unworthy servant." This practice is in harmony with the words of the apostolic constitutions where the celebrant, after praying for others, prays for himself in these words: "We now beseech you for a man of no worth, for myself who am offering to You" etc. (Ap. Const., bk. 8, in Cotelerius, Opera Patrum Apostolicorum, vol. 1, p. 407). Moreover it should be known that in Rome commemoration is made only of the Roman Pontiff since he is not only Supreme Pontiff, but also the bishop of the city of Rome in particular. When the Pope himself says Mass, he prays for himself in precisely the same way as any bishop prays for himself during Mass. In reply to the bishop of Orense who enquired how the Pope commemorated himself during the celebration of Mass, Innocent III, in a letter not yet published but preserved in the Vatican archives (bk. 9, no. 33) replied as follows: "You have also asked to be instructed as to the words used by the Roman Pontiff at the place in the canon of the Mass where a priest of lower rank says 'together with our Pope,' since the Pope is then obviously praying for himself and is subordinate to no bishop. Our reply to your devotedness is this: at that place We say 'together with me your unworthy servant."'

Finally it must be remarked that Latin priests make no commemoration of an archbishop such as a metropolitan in the canon. This point is also rightly made by P. Merati in his Commentaria ad Gavantum (pt. 2, head. 8, no. 5) and the case is the same even if the episcopal see is vacant: "But if the bishop, who is Ordinary of the place in which Mass is being celebrated, has departed this life, the aforesaid words are omitted"-that is, a commemoration is not made-"but it is to be noticed that the Vicar Capitular cannot be named instead of the bishop, since although while the see is vacant he is Ordinary of that place, he is still not the bishop of that diocese. Moreover, the archbishop or the patriarch of the province which includes the diocese of the dead bishop cannot be named, even though he has a certain jurisdiction over it, since an archbishop or a patriarch is not said to be Ordinary in the dioceses of his suffragans."
