Pope Benedict XIV, Ex Quo, paragraphs 9 & 23: “9. The first admonition is thus expressed: ‘It must be known that the priests who will use the Euchologion should be acquainted with the ecclesiastical canons of the holy Fathers and the Constitutions of the Catholic Church in order that they may avoid obvious mistakes in administering the divine Sacraments and performing their other duties. Therefore where commemorations are customarily made in the sacred liturgy, the Roman Pontiff should be first commemorated, then one's own bishop and patriarch, provided they are Catholic. But if either or both of them are schismatic or heretic they should by no means be commemorated.’ Certainly this is in full agreement with the decrees passed at the meeting of the Congregation on May 1, 1746, which We approved and confirmed… [Par. 23.] …Moreover heretics and schismatics are subject to the censure of major excommunication by the law of Can. de Ligur. 23, quest. 5, and Can. Nulli, 5, dist. 19. But the sacred canons of the Church forbid public prayer for the excommunicated as can be seen in chap. A nobis, 2, and chap. Sacris on the sentence of excommunication. Though this does not forbid prayer for their conversion, still such prayer must not take the form of proclaiming their names in the solemn prayer during the sacrifice of the Mass. This fully accords with the ancient practice, as may be seen in Estius in 4. Sententiar., dist. 12, sec. 15. For that purpose it is sufficient to beseech to lead back the wanderers to the way of salvation and to the bosom of holy Mother Church, as is expounded by Sylvius, in 3. part. D. Thomae, vol. 4, quest. 83, art. 1, qu. 9.”
