Pope Gelasius I

Pope Gelasius I served as the bishop of Rome from March 1, 492, until his death on November 21, 496. His pontificate is considered a significant period of transition, placing him stylistically and theologically on the cusp between Late Antiquity and the Early Middle Ages. Scholars suggest that his predecessor, Felix III, may have employed him in drafting papal documents, though this is not definitively certain.

Key Contributions and Papacy

During his time as pope, Gelasius I was a strong advocate for strict Catholic orthodoxy and more assertively demanded obedience to papal authority. This stance inevitably increased tensions between the Western and Eastern Churches. Despite these theological and political struggles, he maintained surprisingly cordial relations with the Ostrogoths, who were Arians and viewed as heretics by Nicene Christians.

Gelasius authored the work "De duabus in Christo naturis" (On the dual nature of Christ), which clearly articulated Catholic doctrine on the subject. He also advocated for the primacy of the See of Rome over the entire Church, East and West, laying the groundwork for papal supremacy claims based on succession from Saint Peter.

Significant Writings and Actions

One of his most influential works was the letter "Duo sunt" (circa 494) addressed to Roman Emperor Anastasius, which discussed the relationship between church and state. This letter had a profound political impact for over a millennium, with later popes quoting from it.

Closer to home, Gelasius I successfully suppressed the ancient Roman festival of the Lupercalia after a protracted contest. His correspondence regarding this issue provided details about the festival's practices of fertility and purification.

Authorship and Legacy

Gelasius was a prolific author, with over 100 of his letters surviving, though many are fragmentary. Six treatises bearing his name are also extant. While his dogmatic letters concerning the Acacian Schism were widely circulated, most of his surviving correspondence dealt with the administration of the church in suburbicarian Italy.

The "Decretum Gelasianum," a list of accepted and rejected books (De libris recipiendis et non recipiendis), is a famous pseudo-Gelasian work believed to be connected to the pressure for orthodoxy during his pontificate. It has traditionally been attributed to Gelasius and influenced the determination of the canon of Sacred Scripture. The "Gelasian Sacramentary," another work attributed to him, is a liturgical book derived from Roman sources with Gallican additions, compiled in the mid-8th century near Paris. While it contains prayers composed by Gelasius, he was not its primary author or compiler.

Gelasius I died on November 21, 496. His feast day is observed on November 21.
