Commemorated January 10
Troparion of St. Gregory, Tone 3
Thou hast shown forth thy watchfulness and wast a fervent preacher of godliness: by the wisdom of thy teachings thou dost gladden the Church's faithful. Righteous Father Gregory, entreat Christ our God to grant us His great mercy.
Kontakion of St. Gregory, Tone 1
Watchful with the eyes of thy soul and a vigilant shepherd for the world, with wisdom and thy fervent intercession thou didst drive off heretics like wolves, keeping thy flock unharmed.
