St. Gregory the Dialogist, as we call him in the East, is one of my favorite Popes of Rome. Not only did he give the West a nice system of tones comparable to the liturgical music of the East, he also composed the Pre-Sanctified Divine Liturgy still used on weekdays during Great Lent by all Orthodox Christians.
He is also beloved of the Orthodox because of some comments he made regarding the relationship of the Roman Papacy to the other sees of Christendom, but I will not seek to provoke controversy by citing those here.
Troparion of St Gregory tone 3
Thou didst excellently dispense the Word of God,/ endowed with discretion of speech, O Hierarch Gregory:/ for by thy life thou didst set the virtues before us,/ and dost radiate the brightness of holiness ./ O righteous Father, pray to Christ our God to grant us His great mercy.
Kontakion of St Gregory tone 8
We praise thee, God-inspired harp of the Church and God-possessed tongue of wisdom;/ for thou didst prove to be an image and model of the Apostles and didst emulate their zeal./ Wherefore we cry to thee: Rejoice, O Gregory the Dialogist.
BTTT for today, 9-03-03, Feast of St. Gregory the Great!
