ISB ~ John 1 v18

No one has ever seen God:God is pure spirit and thus invisible to human eyes (4:24; 1 Tim 6:16). Even still, the face of the Father can be seen in the face of Christ, who is the visible image of the invisible God (14:9; Col 1:15). Only in eternity will we see God as he truly is (1 Cor 13:12) (CCC 151). the only-begotten Son: A significant textual variant reads “God, the only begotten”, which directly asserts the deity of Jesus. The reading followed in the translation can (1) refer to the eternal generation of Christ within the Trinity or (2) mean “unique” and “precious”, as Isaac was the beloved of his father, Abraham (Heb 11:17) (CCC 444).
