Can the biretta be used during the liturgy like a mitre on a bishop?
- During the Procession, before the Opening Rite.
- During the Homily
- During the Recession, after Closing Rite.
And I may be mistaken, but I think the black zuchetto is not allowed to be worn by priest during the liturgy, only bishops and above can wear one.
But can the bishop grant a dispensation to a priest to wear one during the liturgy?
