St. Gregory Palamas Troparion & Kontakion

Troparion, Tone 8 (St. Gregory Palamas)
O light of Orthodoxy, teacher of the Church, its confirmation, O ideal of monks and invincible champion of theologians, O wonderworking Gregory, glory of Thessalonica and preacher of grace, always intercede before the Lord that our souls may be saved!

Kontakion, Tone 8 (St. Gregory Palamas)
Holy and divine instrument of wisdom, joyful trumpet of theology, together we sing your praises, O God-inspired Gregory. Since you now stand before the Original Mind, guide our minds to Him, O Father, so that we may sing to you: “Rejoice, preacher of grace!”
