What is the synoptic problem?
The synoptic problem is an investigation into the existence and nature of the literary interrelationship among the first three “synoptic” gospels. Matthew, Mark, and Luke are called the synoptic gospels, in contrast with John, because they can readily be arranged in a three-column harmony called a “synopsis.” Unlike John, the synoptic gospels share a great number of parallel accounts and parables, arranged in mostly the same order, and told with many of the same words. Any proposed solution to the synoptic problem, therefore, must account for these literary similarities among the synoptics, not so much in terms of their factual content, but in the selection of that content, the arrangement of the material, and wording of the parallels.
