Saint Gregory the Theologian, Archbishop of Constantinople - Troparion & Kontakion
Troparion — Tone 1
The sweet-sounding shepherd’s pipe of your theology / overpowered the trumpeting of the orators; / for having searched the depths of the Spirit / eloquence was also bestowed upon you. / Pray to Christ God, Father Gregory, / that our souls may be saved.
Kontakion — Tone 3
By words of theology you unraveled the complex webs of the orators, / glorious Gregory, / and adorned the Church with the robe of Orthodoxy woven from on high. / Wearing it, she cries out with us, her children: / “Rejoice, O Father, supreme mind of theology.”
