Phos Hilaron: earliest known Christian hymn

Hail, gladdening Light, of His pure glory poured
Who is th'immortal Father, heavenly, blest,
Holiest of Holies--Jesus Christ our Lord!

Now we are come to the sun's hour of rest;
The lights of evening round us shine;
We hymn the Father, Son, and Holy Spirit divine!

Worthiest art thou at all times to be sung
With undefiled tongue,
Son of our God, giver of life, alone:
Therefore in all the world thy glories, Lord, they own. Amen.
