Hail Holy Light (excerpt)

HAIL holy light, ofspring of Heav'n first-born,
Or of th' Eternal Coeternal beam
May I express thee unblam'd? since God is light,
And never but in unapproached light
Dwelt from Eternitie, dwelt then in thee,
Bright effluence of bright essence increate.
Or hear'st thou rather pure Ethereal stream,
Whose Fountain who shall tell? before the Sun,
Before the Heavens thou wert, and at the voice
Of God, as with a Mantle didst invest
The rising world of waters dark and deep,
Won from the void and formless infinite.
