Pope John Paul I He refused to have the millennium-old traditional Papal Coronation and wear the Papal Tiara. He instead chose to have a simplified Papal Inauguration Mass. John Paul I used as his motto "Humilitas". In his notable "Angelus" of 27 August 1978 (delivered on the first full day of his papacy), he impressed the world with his natural friendliness. Sister Margherita Marin, who worked in the Vatican during Luciani's papacy, said in comments made in late 2017 that the pope had admitted the sisters into his apartment chapel for morning Mass, unlike his predecessor Paul VI who had only admitted his secretaries.
Byzantine Papacy was "not only rare but a 'complete anachronism'". Pope Vitalian (657–672) established a "schola cantorum" to train ceremonial chanters, which was almost entirely "in imitation of its Byzantine model". Vatalian also introduced the celebration of the Easter vespers and baptism at Epiphany, both traditions originating in Constantinople. The "liturgical byzantinization" furthered by Vitalian would be continued by his successors. However, the Latin language made a liturgical resurgence—officially replacing Greek—between 660 and 682; Greek again re-emerged during the papacy of Pope Agatho and his successors. By the beginning of the eighth century, bilingual liturgies were common place, with Greek taking precedence.
