With apparent strong conviction of the importance of the Bishop of Rome in the Church, and of the Church as the ongoing sign of Christ’s presence in the world, Leo the Great displayed endless dedication as pope. Elected in 440, he worked tirelessly as “Peter’s successor,” guiding his fellow bishops as “equals in the episcopacy and infirmities.”
Leo is known as one of the best administrative popes of the ancient Church. His work branched into four main areas, indicative of his notion of the pope’s total responsibility for the flock of Christ. He worked at length to control the heresies of Pelagianism—overemphasizing human freedom—Manichaeism—seeing everything material as evil—and others, placing demands on their followers so as to secure true Christian beliefs.
A second major area of his concern was doctrinal controversy in the Church in the East, to which he responded with a classic letter setting down the Church’s teaching on the two natures of Christ. With strong faith, he also led the defense of Rome against barbarian attack, taking the role of peacemaker.
In these three areas, Leo’s work has been highly regarded. His growth to sainthood has its basis in the spiritual depth with which he approached the pastoral care of his people, which was the fourth focus of his work. He is known for his spiritually profound sermons. An instrument of the call to holiness, well-versed in Scripture and ecclesiastical awareness, Leo had the ability to reach the everyday needs and interests of his people. One of his sermons is used in the Office of Readings on Christmas.
It is said of Leo that his true significance rests in his doctrinal insistence on the mysteries of Christ and the Church and in the supernatural charisms of the spiritual life given to humanity in Christ and in his Body, the Church. Thus Leo held firmly that everything he did and said as pope for the administration of the Church represented Christ, the head of the Mystical Body, and Saint Peter, in whose place Leo acted.
Reflection
At a time when there is widespread criticism of Church structures, we also hear criticism that bishops and priests—indeed, all of us—are too preoccupied with administration of temporal matters. Pope Leo is an example of a great administrator who used his talents in areas where spirit and structure are inseparably combined: doctrine, peace, and pastoral care. He avoided an “angelism” that tries to live without the body, as well as the “practicality” that deals only in externals.
