Today our Synod commemorates one of the greatest bishops to serve the city of Rome, Gregory the Great (also counted as the fourth among the four doctors of the Western Church: Augustine, Ambrose, Jerome being the others). From the Synod's website:
One of the great leaders in Europe at the close of the sixth century, Gregory served in both the secular and sacred arenas of his era. As mayor of Rome, he restored economic vitality to his native city, which had been weakened by enemy invasions, pillage, and plague. After he sold his extensive properties and donated the proceeds to help the poor, he entered into full-time service in the Church. On September 3, 590 A.D., Gregory was elected to lead the church in Rome. As Bishop of Rome he oversaw changes and growth in the areas of church music and liturgical development, missionary outreach to northern Europe, and the establishment of a church-year calendar still used by many churches in the western World today. His book on pastoral care became a standard until the 12th century.
The classic form the of the Western eucharistic rite is generally attributed to the work of this great saint. He definitely introduced the Kyrie into its current location and the Lord's Prayer at the end of the great Thanksgiving; Bede also says that he introduced into the canon the petitions: "Order our days in Your peace, preserve us from eternal damnation, and count us among Your chosen flock, through Jesus Christ, our Lord." [Bede, *A History of the English Church and People* Book II, Chapter 1]
From LSB, a hymn attributed to St. Gregory for singing at the morning office:
Father, we praise Thee, now the night is over,
Active and watchful, stand we all before Thee;
Singing, we offer prayer and meditation:
Thus we adore Thee.
Monarch of all things, fit us for Thy mansions;
Banish our weakness, health and wholeness sending;
Bring us to heaven, where Thy saints united,
Joy without ending.
All-holy Father, Son, and equal Spirit,
Trinity blessed, send us Thy salvation;
Thine is the glory, gleaming and resounding
Through all creation. LSB 875
