Many Christians today may think that the canon of the New Testament simply appeared on the scene one day, soon after the death of Jesus, but nothing could be farther from the truth. As it turns out, we are able to pinpoint the first time that any Christian of record listed the twenty-seven books of our New Testament as the books of the New Testament—neither more nor fewer. Surprising as it may seem, this Christian was writing in the second half of the fourth century, nearly three hundred years after the books of the New Testament had themselves been written.
