John Dominic Crossan, professor of biblical studies at DePaul University, Chicago,
offers a reconstructed inventory of words placed on Jesus' lips
that actually go back to the historical Jesus.
However, Crossan urges that as you read them,
these words are not a list to be read;
they are not a sermon to be preached.
They are a score to be played and a program to be enacted.
