evening, as for John Paul I, but in the morning. Referring in his inauguration homily to coronation with the papal tiara, John Paul II said: "This is not the time to return to a ceremony and an object considered, wrongly, to be a symbol of the temporal power of the Popes." In his 1996 apostolic constitution Universi Dominici Gregis, John Paul II laid down that a "solemn ceremony of the inauguration of a pontificate" should take place, but did not specify its form, which he left to each pope to decide. Modern inauguration Four modern popes have now used an inauguration ceremony without coronation: Pope John Paul I, Pope John Paul II, (both in 1978), Pope Benedict XVI (2005) and Pope Francis (2013).

Pope Benedict XVI maintained those changes and also shortened, as explained below, the ceremony of homage previously paid at a papal inauguration by each cardinal individually, repeating the "act of homage and obedience" made in the conclave to the new pope before the announcement of his election to the people. The ceremony does not include the alleged Papal Oath that some traditionalist Catholics claim, without evidence, to have been sworn by the popes before John Paul I. They criticise its absence, and some sedevacantist groups refuse to accept the legitimacy of the modern popes due to the absence of both the alleged oath and the symbolic tiara. Inauguration of Benedict XVI Pope Benedict XVI celebrated his inauguration on 24 April 2005 after being elected on 19 April 2005 having approved new procedures for the papal inauguration previously on 20 April 2005 the day after his election. The ceremony began with the pope and the cardinals kneeling at the Tomb of Saint Peter beneath the high altar of Saint Peter's Basilica—the popes are, according to Catholic dogma, the successors of Saint Peter, the first head of the Church in Rome—to give him homage, and ask his prayers. Pope Benedict said, "I leave from where the Apostle arrived." The pope and the cardinals then went in procession to Saint Peter's Square for the inauguration Mass, while the "Laudes Regiæ" was chanted, asking
