The Vigil of Christ's Nativity

Glory to Your coming that restored humankind to life.

Glory to that One Who came to us by His First-born.

Glory to that Silent One Who spoke by means of His Voice.

Glory to that Sublime One Who was seen by means of His Voice.

Glory to that Sublime One Who was seen by means of His Dawn.

Glory to the Spiritual One Who was well-pleased

that His Child should become a body so that through Him His power might be felt

and the bodies of His kindred might live again.

Glory to that Hidden One Whose Child was revealed.

Glory to that Living One Whose Son became a mortal.

Glory to that Great One Whose Son descended and became small.

Glory to that Great One Who fashioned Him,

the Image of His greatness and Form for His hiddenness.

With the eye and the mind–with both of them we saw Him.

Glory to that Hidden One Who even to the mind

is utterly imperceptible to those who investigate Him.

But by His grace through His humanity

a nature never before fathomed is now perceived.

St. Ephrem the Syrian (4th C), "Hymns On the Nativity"
