"The early Christians' opponents all accepted that Jesus existed, taught, had disciples, worked miracles, and was put to death on a Roman cross. As in our day, debate and disagreement centred largely not on the story but on the significance of Jesus. Today nearly all historians, whether Christians or not, accept that Jesus existed and that the gospels contain plenty of valuable evidence which has to be weighed and assessed critically."
