Papal household

[4] The Papal Chapel consists of ecclesiastics who participate in religious ceremonies wearing their liturgical vestments or the dress proper to their rank and office.

[5] Historically, chanted divine service was held daily in the papal palace, with the Pope in person celebrating or assisting at Pontifical Mass on certain days.

The roles and positions in the papal household and court evolved and changed over time, and included hostiarii, vestararius, vicedominus, nomenclator, cubiculario (chamberlain), sacellarius, praelatini palatini, bibliothecarius, scutiferi, cancellarius, protonotaries, primicerius, secundicerius, defensor, and many more.

According to the motu proprio: "Many of the offices entrusted to members of the Papal Household were deprived of their function, continuing to exist as purely honorary positions, without much correspondence to concrete needs of the times.

"[13] In the Papal Chapel, the following positions were altered or suppressed: Palatine Cardinals (Cardinali Palatini); prelates di fiocchetto; Prince-Assistants to the Throne (Principi assistenti al Soglio); Majordomo of His Holiness; the Interior Minister; Commander of Santo Spirito; Roman Magistrate; Master of the Sacred Apostolic Hospice; Chamberlains of Honor in abito paonazzo; Secret Chaplains and Secret Chaplains of Honor; Secret Clerics; Confessor of the Pontifical Family; Candle-Carrying Acolytes (Ceroferari); Guardian of the Sacred Tiara; Mace-Bearer; and Apostolic Messenger (Cursori Apostolici).

Likewise, the Secret Chamberlains of the Cape and Sword (di cappa e spada) were retained under the title Gentlemen of His Holiness, and the Bussolanti took the new name of Attachés of the Antechamber.
