epseusamen se ten aletheian, loge

Gregory of Nazianzus, b.329

O Word of Truth! in devious paths

My wayward feet have trod;

I have not kept the day serene

I gave at morn to God.

And now 'tis night, and night within;

O God, the light hath fled!

I have not kept the vow I made

When morn its glories shed.

For clouds of gloom from nether world

Obscured my upward way;

O Christ the Light, Thy light bestow

And turn my night to day!
