He is now the "proto-deacon" of the College of Cardinals
That, of course, is presuming that there would be a conclave before his tenure as proto-deacon ends … and also presuming that he himself wouldn’t be elected the next pope!
Cardinal Sarah, 72, has become the eldest of the cardinals-deacon voters, following the consistory of May 19. The older cardinal-deacon, the Italian Raffaele Martino, is no longer a voter, being more than 80 years old. On May 19, Pope Francis made changes in the order of the cardinals, some passing from deacons to priests.
In the past, the cardinal proto-deacon was also the one who crowned the pope with the tiara—symbol of the pope’s triple power as bishop of Rome, head of state of the Vatican, and universal teacher. Since the abolition of the coronation after Paul VI, the cardinal proto-deacon places the pallium, symbol of pastoral authority, on the shoulders of the pope at the inaugural mass of the pontificate.
Cardinal Sarah is the prefect of the Congregation for Divine Worship and the Discipline of the Sacraments.
He is a native of Conakry, Guinea, and was ordained a priest of that archdiocese in 1969 and then made archbishop there in 1979. Since 2001 he has been serving in the Roman Curia.
