There is doubtless difficulty in reconciling the passage in Genesis 18 with the statement in John 1 :18, that "No man hath seen God at any time." Authorities regarded the Genesis passage as relating to one of the "theophanies" of the Old Testament; that is, a real appearance of God to man. It is believed, however, that these appearances were of Christ the Son, rather than God the Father. The New Testament teaches that Christ existed co-eternally with the Father, and it is not inconceivable that he would at times take the appearance of humanity when he wished especially to make himself known to men. This explanation rec onciles all these occurrences with the statement of John that no one has seen God; that is, God the Father. Christ is the personal manifestation of God to man.
