Not only do the Gospels contain basic and irreconcilable differences in their accounts of Jesus, they have been put together according to a traditional Jewish practice known as "midrash", which involved reworking and enlarging on scripture. This could entail the retelling of older biblical stories in new settings. Thus, Mark’s Jesus of Nazareth was portrayed as a new Moses, with features that paralleled the stories of Moses. Many details were fashioned out of specific passages in scripture. The Passion story itself is a pastiche of verses from the Psalms, Isaiah and other prophets, and as a whole it retells a common tale found throughout ancient Jewish writings, that of the Suffering and Vindication of the Innocent Righteous One. It is quite possible that Mark, at least, did not intend his Gospel to represent an historical figure or historical events, and designed it to provide liturgical readings for Christian services on the Jewish model. Liberal scholars now regard the Gospels as "faith documents" and not accurate historical accounts. [See "Part Three", the John Shelby Spong book review, and responses to Jan and Johnson.]
