Ode 1. Irmos. I will open my mouth.**

Spiritually enriched with mysteries, blessed Father inspired by God, you uttered words of doctrines; through which you became a shepherd of the Church, leading it over to a heavenly sheepfold.

You sped towards the height of the ascents of Scripture, and explored its irresistible and unravaged beauty with purity of mind, through which you have been declared a lantern of high priesthood.

You encountered the divine illumination of the spiritual light, Father, and made our minds radiant, while with rightly expounding rays you reduced heresies to ashes and burned them up through the Spirit.

Child-birth without knowledge of man is perfected in you; from you the Word above all godhead comes forth, and, keeping you virgin after childbirth, appears as perfect God and man.
