Thou Who Art Three in Unity

Thou who art Three in unity,
True God from all eternity,
The sun is fading from our sight,
Shine Thou on us with heavenly light.

We praise Thee with the dawning day,
To Thee at even also pray;
With our poor song we worship Thee
Now, ever, and eternally.

Let God the Father be adored,
And God the Son, the only Lord,
And God the Holy Spirit be
Adored throughout eternity!

~An imitation from the Gregorian hymn, "O lux beata trinitas."
