Shortly after assuming office, Celestine issued a
papal bull granting a rare
plenary indulgence to all pilgrims visiting
Santa Maria di Collemaggio through its holy door on the anniversary of his papal coronation. The
Celestinian forgiveness (
Perdonanza Celestiniana) festival is celebrated in L'Aquila every 28–29 August in commemoration of this event. With no political experience, Celestine proved to be an especially weak and ineffectual pope. He held his office in the
Kingdom of Naples, out of contact with the
Roman Curia and under the complete power of King
Charles II. He appointed the king's favorites to Church offices, sometimes several to the same office. One of these was
Louis of Toulouse, whom Celestine ordered given
clerical tonsure and
minor orders, although this was not carried out. He renewed a decree of
Pope Gregory X that had established stringent rules for
papal conclaves after a similarly prolonged election. In one decree, he appointed three cardinals to govern the Church during
Advent while he fasted, which was again refused. Realizing his lack of authority and personal incompatibility with papal duties, he consulted with Cardinal
Benedetto Caetani (his eventual successor) about the possibility of resignation. In the formal instrument of renunciation, he cited his reasons for resigning as "The desire for humility, for a purer life, for a stainless conscience, the deficiencies of his own physical strength, his ignorance, the perverseness of the people, his longing for the tranquility of his former life". Having divested himself of every outward symbol of papal dignity, he slipped away from Naples and attempted to retire to his old life of solitude. The next pope to resign of his own accord was
Gregory XII in 1415 (to help end the
Western Schism), followed by
Benedict XVI in 2013, 719 years later. ==Retirement, death, and canonization==
