Jesus answered Nathaniel:
"Nathaniel, never permit yourself for one moment to believe the Scripture records which tell you that the God of love directed your forefathers to go forth in battle to slay all their enemies--men, women, and children. Such records are the words of men, not very holy men, and they are not the word of God. The Scriptures always have, and always will, reflect the intellectual, moral, and spiritual status of those who create them. Have you not noted that the concepts of Yahweh grow in beauty and glory as the prophets make their records from Samuel to Isaiah? And you should remember that the Scriptures are intended for religious instruction and spiritual guidance. They are not the works of either historians or philosophers.
P.2082 - §6 Do not overlook the value of your spiritual heritage, the river of truth running down through the centuries, even to the barren times of a materialistic and secular age. In all your worthy efforts to rid yourselves of the superstitious creeds of past ages, make sure that you hold fast the eternal truth. But be patient! when the present superstition revolt is over, the truths of Jesus' gospel will persist gloriously to illuminate a new and better way.
