Irmos: Isaiah, rising at dawn out of the night, and beholding the never-waning light of Thy theophany, O Christ, which hath mercifully come to pass for us, cried out: Come, O ye who have been illumined! Wash ye with divine water, and manifestly cleanse your souls and bodies by the Spirit!
Through fire and the Spirit and by water Thou makest mortals new, as the Creator and new Adam, accomplishing a strange regeneration and a wondrous restoration, making them new through God-given baptism without first breaking and melting them down.
Thou makest souls new through the Spirit, and by water dost sanctify their body, which is composed of divers parts, building up the life of man; for as the Physician of souls and bodies with wise forethought Thou appliest the remedy which each part requireth.
O Thou Who wast begotten of the Father before time began and didst issue forth from the pure one, Thou camest unto him who was born of the barren woman, asking for baptism as a man; and out of water and through the Spirit Thou didst mystically make the Church, which before was childless, full of children.
