Genesis 1:1-2 
In the beginning God created the heaven and the earth. 
and the earth was without form, and void; 
and darkness was upon the face of the deep. 
And the Spirit of God moved upon the face of the waters. 

 Paradise Lost, Book VII: 205-209 
Heaven opened wide 
Her ever-during gates, harmonious sound 
On golden hinges moving, to let forth 
The King of Glory, in his powerful Word 
And Spirit coming to create new worlds. 
—John Milton (1608-1674) 

 Genesis 1:3 
And God said, let there be light. 

Veni Sancte Spiritus 
Veni, Sancte Spiritus, 
et emitte caelitus 
Lucis tuae radium. 
Veni, dator munerum, 
Veni, lumen cordium. 

 O lux beatissima, 
Reple cordis intima 
Tuorum fidelium. 
—Twelfth Century chant text 

 Come, Holy Spirit, 
Send forth from heaven 
The ray of thy light. 
come, giver of gifts, 
Come, light of hearts. 

 O Light most blessed, 
Fill the inmost heart 
Of all thy faithful. 

 Paradise Lost, Book III: 1-6 
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 unapproachèd light 
Dwelt from Eternitie, dwelt then in thee, 
Bright effluence of bright essence increate. 
—Milton
