Pope St. Gregory the Great (540-604 A.D.) was the son of a wealthy Roman senator. His mother and two of his aunts are also saints, which provided him with a strong and devout religious upbringing. His skill in grammar and rhetoric were exceptional, and he followed in his father's political footsteps by serving in public office as the prefect of Rome. Discerning a call to the religious life, he sold all of his possessions and converted his home into a Benedictine monastery. He used his liquidated assets to build six other monasteries. Because of his talent and intelligence he was unanimously chosen to become the Roman Pontiff, the first monk to become Pope. During his lifetime Rome was sacked by invading barbarian hordes, and the city also suffered severe damage from floods and pestilence, causing his pontificate to be an important one. He brought stability and order to the Church in a time of great societal and cultural upheaval. His profound influence on the doctrine, organization, and discipline of the Church cannot be underestimated, thus earning him the title "The Great" which he shares with only two other popes. For his abundant doctrinal and spiritual writings he is also considered to be one of the four great Doctors of the Latin Church. He is most commonly known for promoting and standardizing the sacred music of liturgical worship, now called "Gregorian Chant." Pope St. Gregory the Great is the patron of popes, masons, choir boys, singers, teachers, and musicians. His feast day is September 3rd.
