Wisdom, sacred and divine organ, theology of the bright trumpet, we sing to you, Gregory, the God-speaker, but, as wiser, the First Mind now stands, to that mind Our father, instruct, so we call to you: Rejoice, preacher of grace.
Ikos:
An angel appeared on earth, the ineffable Divine proclaiming to the corruptible, for disembodied voices, born of men and living in the body, surprised you and made you call, God-speaking, this: Rejoice, for whose sake the Light was preached; Rejoice, for his sake I drove away the darkness; Rejoice, proclaimer of the Uncreated Divinity; Rejoice, thou who hast created nature and is truly a accuser; Rejoice, unclimbable height, God's nature of rivers; Rejoice, the depth of visual inconvenience, the action of rivers; Rejoice, for thou art the glory of God; Rejoice, for you have renounced the wisdom of the evil ones; Rejoice, luminary, showing the Sun; Rejoice, vessel of divine drink; Rejoice, for where the truth shines; Rejoice, even though darkness has darkened; Rejoice, preacher of grace.
