43 That is why We are deeply pained when We hear that not a few of Our Brother Bishops are being attacked and persecuted not only in their own persons, but - what is more cruel and heartrending for them - in the faithful committed to their care, in those who share their apostolic labors, even in the virgins consecrated to God; and all this, merely because they are a pattern of the flock from the heart and guard with energy and loyalty, as they should the sacred "deposit of faith" confided to them; merely because they insist on the sacred laws that have been engraved by God on the souls of men, and after the example of the Supreme Shepherd defend their flock against ravenous wolves. Such an offence We consider as committed against Our own person and We repeat the noble words of Our Predecessor of immortal memory Gregory the Great: "Our honor is the honor of the Universal Church; Our honor is the united strength of Our Brethren; and We are truly honored when honor is given to each and every one."
