Nie udzielam żadnej odpowiedzi - stąd not for grading - chciałam tu tylko zamieścić (bez ograniczeń długości tekstu) fragment z Catholic Encyclopaedia, wyjaśniający, kim jest monsignor:

"Among ecclesiastics the title Monsignore implies simply a distinction bestowed by the highest ecclesiastical authority, either in conjunction with an office or merely titular. In any case it bears with it a certain prescribed dress. To counteract a widely spread misconception we may state here that the pope does not bestow the title Monsignore, but a distinction of some sort to which this title is attached. Accordingly it is quite incorrect to say that any one has been appointed aMonsignor by the pope. If we may be permitted to use a comparison, Monsignor in the spiritual order corresponds to the word officer in the military. The highest general and the youngest lieutenant are equally officers, and the most venerable patriarch bears the title Monsignor as well as the simplest honorary chaplain. Thus among prelates, both higher and lower, it is no badge of distinction except as it denotes in a very general way an elevation above the ranks of the clergy. Those only bear the title of Monsignor, who are familiares summi pontificis, those who, by virtue of some distinction bestowed upon them, belong as it were to the family and the retinue of the Holy Father. These familiares are entitled to be present in the cappella pontificia (when the pope celebrates solemn Mass), and to participate in all public celebrations purely religious or ecclesiastical in character, at which the pope, the cardinals, and the papal retinue assist. it is assumed that they will appear in the robes corresponding to their respective offices."

A sięgnęłam po to dlatego, że pewien powszechnie znany prałat posługuje się tym tytułem, a nawet sprzedaje wino pod nazwą Monsignore.

Prałat - tak mam na akcie chrztu z NJ. Można poklikać na Google i sprawdzić. Rev. Msgr. Arkadiusz Klejnowski - ks. prałat Arkadiusz Klejnowski
