Prelate of Honour of His Holiness

A Prelate of Honour of His Holiness is a Catholic prelate to whom the Pope has granted this title of honour.

They are addressed as Monsignor and have certain privileges as regards clerical clothing.

Overview
Before the motu proprio Pontificalis Domus of 28 March 1968, Honorary Prelates (HP) were called Domestic Prelates (Antistites Urbani). Those who held certain offices were also granted the title, such as an Archbishop or Bishop Assistant at the Pontifical Throne or a member of the Roman Prelature. The title was retained by archbishops, bishops and protonotaries apostolic who had been awarded it before their appointment to those positions.

The Prelates of Honor are entitled Reverend Monsignor. Historically associated with the chamberlain of the papal court, it is the second rank of monsignor: above Chaplain to His Holiness, but below Protonotary Apostolic.
