For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life.

Alcuin of York
AD 804
Truly through the Son of God shall the world have life; for no other cause came He into the world, except to save the world. God sent not His Son into the world to condemn the world, but that the world through Him might be saved.
He who believes in Him, and cleaves to Him as a member to the head, will not be condemned.
He then gives the reason why he who believes not is condemned, viz. because he believes not in the name of the only begotten Son of God. For in this name alone is there salvation. God has not many sons who can save; He by whom He saves is the Only Begotten.
