The chief priests’ and elders’ question has been repeated through the centuries of Christian history. Attempts to answer the question as posed inevitably result in diverse forms of Christian heresy, for the attempt to establish grounds more determinative than Jesus’ life, death, and resurrection for why we should believe in him results in idolatry. If one needs a standard of truth to insure that Jesus is the Messiah, then one ought to worship that standard of truth, not Jesus. There is no place one might go to know with certainty that Jesus is who he says he is. To know that Jesus is the Son of God requires that we take up his cross and follow him. Having taken up the cross, Christians discover they have no fear of the truth, no matter from where it might come.
