Today, the Church remember Gregory the Great.

Pope Saint Gregory I (c. A.A. 540 – 12 March 604), commonly known as Saint Gregory the Great, was Pope of the Catholic Church from A.D. 3 September 590. He is famous for instigating the first recorded large-scale mission from Rome, the Gregorian Mission, to convert a pagan people to Christianity. Gregory is also well known for his writings, which were more prolific than those of any of his predecessors as pope.

A Roman senator's son and himself the Prefect of Rome at the age of 30 years, Gregory tried the monastery but soon returned to active public life, ending his life and the century as pope. Although he was the first pope from a monastic background, his prior political experiences may have helped him to be a talented administrator, who successfully established papal supremacy. During his papacy, he greatly surpassed with his administration the emperors in improving the welfare of the people of Rome. He also was an able theologian, and successfully challenged the theological views of Patriarch Eutychius of Constantinople before the emperor Tiberius II. Gregory regained papal authority in Spain and France and sent missionaries to England. The realignment of barbarian allegiance to Rome from their Arian Christian alliances shaped medieval Europe. Gregory saw Franks, Lombards, and Visigoths align with Rome in religion.

Gregory was born into a period of upheaval in Italy. From A.D. 542 the so-called Plague of Justinian swept through the provinces of the empire, including Italy. The plague caused famine, panic, and sometimes rioting. In some parts of the country, over 1/3 of the population was wiped out or destroyed, with heavy spiritual and emotional effects on the people of the Empire. Politically, although the Western Roman Empire had long since vanished in favour of the Gothic kings of Italy, during the A.D. 540s Italy was gradually retaken from the Goths by Justinian I, emperor of the Eastern Roman Empire ruling from Constantinople. As the fighting was mainly in the north, the young Gregory probably saw little of it. Totila sacked and vacated Rome in A.D. 546, destroying most of its population, but in A.D. 549 he invited those who were still alive to return to the empty and ruined streets. It has been hypothesized that young Gregory and his parents retired during that intermission to their Sicilian estates, to return in A.D. 549. The war was over in Rome by A.D. 552, and a subsequent invasion of the Franks was defeated in A.D. 554. After that, there was peace in Italy, and the appearance of restoration, except that the central government now resided in Constantinople.

On his father's death, Gregory converted his family villa into a monastery dedicated to the apostle Saint Andrew (after his death it was rededicated as San Gregorio Magno al Celio). In his life of contemplation, Gregory concluded that "in that silence of the heart, while we keep watch within through contemplation, we are as if asleep to all things that are without."

Gregory is known for his administrative system of charitable relief of the poor at Rome. They were predominantly refugees from the incursions of the Lombards. The philosophy under which he devised this system is that the wealth belonged to the poor and the church was only its steward. He received lavish donations from the wealthy families of Rome, who, following his own example, were eager, by doing so, to expiate their sins. He gave alms equally as lavishly both individually and en masse.

The state in which Gregory became pope in A.D. 590 was a ruined one. The Lombards held the better part of Italy. Their predations had brought the economy to a standstill. They camped nearly at the gates of Rome. The city was packed with refugees from all walks of life, who lived in the streets and had few of the necessities of life. The seat of government was far from Rome in Constantinople, which appeared unable to undertake the relief of Italy. The pope had sent emissaries, including Gregory, asking for assistance, to no avail. In A.D. 590, Gregory could wait for Constantinople no longer. He organized the resources of the church into an administration for general relief. Gregory began by aggressively requiring his churchmen to seek out and relieve needy persons and reprimanded them if they did not. To pay for his increased expenses he liquidated the investment properties of the Church, including his own vast holdings of land, and paid the expenses in cash. 

Money, however, was no substitute for food in a city that was on the brink of famine. Even the wealthy were going hungry in their villas. The church now owned between 1,300 and 1,800 square miles (3,400 and 4,700 km2) of revenue-generating farmland divided into large sections called patrimonia. It produced goods of all kinds, which were sold, but Gregory intervened and had the goods shipped to Rome for distribution.

Distributions to qualified persons were monthly. However, a certain proportion of the population lived in the streets or were too ill or infirm to pick up their monthly food supply. To them Gregory sent out a small army of charitable persons, mainly monks, every morning with prepared food. It is said that he would not dine until the indigent were fed. When he did dine he shared the family table, which he had saved (and which still exists), with 12 indigent guests. To the needy living in wealthy homes he sent meals he had cooked with his own hands as gifts to spare them the indignity of receiving charity. These and other good deeds and charitable frame of mind completely won the hearts and minds of the Roman people. They now looked to the papacy for government, ignoring the rump state at Constantinople, calling him a fool for his pacifist dealings with the Lombards. 

Pope Gregory had strong convictions on missions: "Almighty God places good men in authority that He may impart through them the gifts of His mercy to their subjects. And this we find to be the case with the British over whom you have been appointed to rule, that through the blessings bestowed on you the blessings of heaven might be bestowed on your people also." 

He is credited with re-energizing the Church's missionary work among the non-Christian peoples of northern Europe. He is most famous for sending a mission, often called the Gregorian mission, under Augustine of Canterbury, prior of Saint Andrew's, where he had perhaps succeeded Gregory, to evangelize the pagan Anglo-Saxons of England. It seems that the pope had never forgotten the English slaves whom he had once seen in the Roman Forum. The mission was successful, and it was from England that missionaries later set out for the Netherlands and Germany. The preaching of non-heretical Christian faith and the elimination of all deviations from it was a key element in Gregory's worldview, and it constituted one of the major continuing policies of his pontificate.

Throughout the Middle Ages he was also known as "the Father of Christian Worship" because of his exceptional efforts in revising the Roman liturgical worship of his day.

Blessed Gregory, we live in an age of poverty, famine, and war; and in the Church we face heterodoxy, even apostasy, and often the debasement of worship, even as did you in your earthly life. You who worked so tirelessly for the plight of the hungry, the poor, and refugees; for making peace with enemies; for sending out missionaries to share the orthodox and catholic Faith with those who had never head the Good News in Jesus; and labored for the enrichment and ennoblement of Christian worship... Ora pro nobis. 

Amen.
