The use of the pallium is reserved to the pope and archbishops who are metropolitans, but the latter may not use it until it is conferred upon them by the pope, normally at the celebration of the Feast of Saints Peter and Paul in June. Pope Francis modified the ritual of conferring the pallium in January 2015: The pallia will be blessed on the feast of Saints Peter and Paul in Saint Peter's Basilica; the metropolitan archbishops, however will receive those pallia in a separate ceremony within their home dioceses from the hands of the Apostolic Nuncio (who is the personal representative of the pope in their respective countries). The pallium is also conferred upon the Latin Rite Patriarch of Jerusalem. Previous traditions that allowed some other bishops to use the pallium were ended by Pope Paul VI in a motu proprio in 1978. A metropolitan archbishop may wear his pallium as a mark of his jurisdiction not only in his own archdiocese but anywhere in his ecclesiastical province whenever he celebrates Mass.
