A Chaplain of His Holiness is a priest to whom the Pope has granted this title. They are addressed as Monsignor and have certain privileges, such as regards ecclesiastical dress.[1][2]
In accordance with the motu proprio Pontificalis Domus of 28 March 1968, those priests who formerly were called Supernumerary Privy Chamberlains continued to be part of the Papal Household, under the new name of Chaplains of His Holiness. Lower ranks of Privy Chamberlains (Honorary Chamberlains of Purple Robes, Chamberlains extra Urbem, Honorary Privy Chaplains, and Honorary Chaplains extra Urbem) were abolished.[3]
Their origin dates back to the time of Pope Urban VIII. They provide unpaid service since the pontificate of Pope Pius VI. The document of their nomination, generally granted at the request of their bishop, is drawn up by the Secretariat of State.[3]
The members of the chapters of one church in Rome and the cathedral in Lodi hold this title durante munere (i.e., while holding that office).[3]
The title no longer expires but requires renewal on the death of the Pope who granted it.[3]
