Venerable Gregory of Sinai - Troparion & Kontakion
Troparion — Tone 5
Adorned with sanctity of soul, as a pure vessel of divine vision, / you proved to be a reflection of the angelic life. / Therefore, you shone forth spiritually with the radiance of the virtues, / O Father Gregory, the boast of Sinai and Athos; / and you guide us unerringly unto the salvation of our souls.
