I shall explore how Matthew and Luke use the text of Mark's gospel as a primary source for their own gospel accounts. (This model of derivation is that of most contemporary scholarship.) We will look at how, as authors, Matthew and Luke both adapt the wording and alter the sequence of those stories and sayings they take from Mark. We will consider the significance of, and possible reasons for, these changes. Why were they made? I will provide a running analysis of Matthew's and Luke's adaptations as we read through the gospels, comparing the evangelists' similar stories. You will need a copy of the King James Bible. (Matthew and Luke's second shared source -the lost, hypothetical "Q" - and John's very different gospel, will hopefully form the subjects of classes in 2021-2 and 2022-3.)
