He received a good education, learning to read and write, as well as studying science and philosophy. He joined the Church at a young age and became a deacon in his 20s. By his early 30s, his reputation had spread beyond national borders. He played a role in opposing Constantinople’s archbishop Nestorius and was recognized for his intelligence and sense of justice.

Papacy

Leo became the pope in 440 after the death of Pope Sixtus III. He worked tirelessly to promote unity among different sects of Christianity and to combat heresies that threatened the Western Church. He successfully rooted out the heresies of Pelagianism and Manichaeism, saving the orthodox teachings of the Christian Church. Leo also became more involved in political and administrative matters, working to bring unity among sects of Christianity and promoting the papal primacy based on the succession of Peter the Apostle.

Negotiating Skills and Writing

In 452, Leo played a role in negotiating with Attila the Hun, who was invading Italy. The details of the meeting are not well-documented, but Attila withdrew, and many historians credit Leo’s negotiating skills. Leo was also an accomplished writer, addressing the debate about the true identity of Jesus Christ in his sermons and letters. He argued that Jesus was both divine and human, making significant contributions to Christology.

Humanitarian Work and Sermons

Leo devoted much of his time to helping the people of Rome during times of difficulty, such as famines, poverty, and refugee crises. He inspired others to engage in humanitarian work and emphasized the importance of healing the world’s sufferings. His sermons were widely recognized for their ability to reach people and meet their needs. His letters and sermons have survived and serve as testaments to his great life.

Death & Legacy

Pope Leo I passed away on November 10, 461, in Rome. He was buried as close to Peter the Apostle as possible, fulfilling his last wish. In 1754, Pope Benedict XIV honored Leo with the title of “Doctor of the Church,” and he is celebrated on November 10 as his feast day. The Eastern Orthodox Church and the Eastern Catholic Churches also celebrate “Saint Leo Day” on February 18 each year.
