In like manner bishops bind themselves to things pertaining to perfection when they take up the pastoral duty, to which it belongs that a shepherd "lay down his life for his sheep," according to John 10:15. Wherefore the Apostle says (1 Tim. 6:12): "Thou . . . hast confessed a good confession before many witnesses," that is to say, "when he was ordained," as a gloss says on this passage. Again, a certain solemnity of consecration is employed together with the aforesaid profession, according to 2 Tim. 1:6: "Stir up the grace of God which is in thee by the imposition of my hands," which the gloss ascribes to the grace of the episcopate. And Dionysius says (Eccl. Hier. v) that "when the high priest," i.e. the bishop, "is ordained, he receives on his head the most holy imposition of the sacred oracles, whereby it is signified that he is a participator in the whole and entire hierarchical power, and that not only is he the enlightener in all things pertaining to his holy discourses and actions, but that he also confers this on others."
Reply Obj. 1: Beginning and increase are sought not for their own sake, but for the sake of perfection; hence it is only to the state of perfection that some are admitted under certain obligations and with solemnity.
Reply Obj. 2: Those who enter the state of perfection do not profess to be perfect, but to tend to perfection. Hence the Apostle says (Phil. 3:12): "Not as though I had already attained, or were already perfect; but I follow after, if I may by any means apprehend": and afterwards (Phil. 3:15): "Let us therefore as many as are perfect, be thus minded." Hence a man who takes up the state of perfection is not guilty of lying or deceit through not being perfect, but through withdrawing his mind from the intention of reaching perfection.
Reply Obj. 3: Martyrdom is the most perfect act of charity. But an act of perfection does not suffice to make the state of perfection, as stated above (A. 4). _______________________
SIXTH ARTICLE [II-II, Q. 184, Art. 6]
Whether All Ecclesiastical Prelates Are in the State of Perfection?
Objection 1: It would seem that all ecclesiastical prelates are in a state of perfection. For Jerome commenting on Titus 1:5, "Ordain . . . in every city," etc. says: "Formerly priest was the same as bishop," and afterwards he adds: "Just as priests know that by the custom of the Church they are subject to the one who is placed over them, so too, bishops should recognize that, by custom rather than by the very ordinance of our Lord, they are above the priests, and are together the rightful governors of the Church." Now bishops are in the state of perfection. Therefore those priests also are who have the cure of souls.
Obj. 2: Further, just as bishops together with their consecration receive the cure of souls, so also do parish priests and archdeacons, of whom a gloss on Acts 6:3, "Brethren, look ye out . . . seven men of good reputation," says: "The apostles decided here to appoint throughout the Church seven deacons, who were to be of a higher degree, and as it were the supports of that which is nearest to the altar." Therefore it would seem that these also are in the state of perfection.
Obj. 3: Further, just as bishops are bound to "lay down their life for their sheep," so too are parish priests and archdeacons. But this belongs to the perfection of charity, as stated above (A. 2, ad 3). Therefore it would seem that parish priests and archdeacons also are in the state of perfection.
On the contrary, Dionysius says (Eccl. Hier. v): "The order of pontiffs is consummative and perfecting, that of the priests is illuminative and light-giving, that of the ministers is cleansing and discretive." Hence it is evident that perfection is ascribed to bishops only.
