Grant argued for a form of the multi-source hypothesis in relation to the synoptic problem. He argued in his 1957 work, The Gospels, Their Origin and Their Growth, that Matthew, Mark, and Luke all draw from the same collection of myths, legends, miracle tales, paradigms, and apothegms.[6]
Grant's view that the author of the Gospel of John was "part of a group of early Christian gnostic-mystics" has since been discredited.[7]
