Prelate of Honour of His Holiness
[1][2] Before the motu proprio Pontificalis Domus of 28 March 1968, Honorary Prelates (HP) were called Domestic Prelates (Latin: 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.[3] 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.
