Editing Tonsure (section)

=====Clerical tonsure=====
Since the issuing of ''Ministeria quaedam'' in 1972,<ref name=Motu_Poprio/> certain institutes have been authorized to use the first clerical tonsure, such as the [[Priestly Fraternity of Saint Peter]] (1988), the [[Institute of Christ the King Sovereign Priest]] (1990), and the [[Personal Apostolic Administration of Saint John Mary Vianney]] (2001).

Although the tonsure itself is obsolete, the wearing of a skull cap, called a [[zucchetto]], in church to keep the head warm, which the fuller form of clerical tonsure led to, still survives.  The zucchetto is worn by the [[pope]] (in white), [[Cardinal (Catholicism)|cardinals]] (in red) and [[bishop]]s (in purple) both during and outside of formal religious ceremonies. Priests may wear a simple black zucchetto, only outside of religious services, though this is almost never seen except on abbots, who continue to wear the black zucchetto, or abbots of the Order of Canons Regular of Premontre, who wear white. Another congregation of Canons Regular, the Canons Regular of the Lateran, wear a white zucchetto as part of their proper habit. Some priests who held special titles (certain ranks of [[monsignori]] and some canons, for instance) formerly wore black zucchettos with red or purple piping, but this too has fallen out of use except in a few, extremely rare cases.
