John 5:47

47.But if you do not believe his writings. Christ appears here to claim less authority for himself than for Moses; and yet we know that heaven and earth have been shaken by the voice of the Gospel, (Hebrews 12:26.) But Christ accommodates his discourse to those to whom he speaks; for the authority of the Law was, beyond all controversy, held sacred among the Jews; and thus it was impossible that Christ should be inferior to Moses. To the same purpose is the contrast between writings and words; for he shows their unbelief to be more aggravated, because the truth of God, recorded in an authentic form, has no authority with them.
