THE MARKAN PRIORITY DEBATE Chris discusses the Markan Priority (the idea that the Gospel of Mark was the first of the four gospels written), as the teaching of this theory continues to be normalized in Christian circles. For the overwhelming majority of history, scholars have accepted that Matthew was the first gospel, since early Church writers always said so. That is the reason Matthew appears first in our bibles, and then Mark. But since the discovery of the Codex Sinaiticus in the 19th century, skeptics have questioned the ordering of the gospels, and in doing so, have attempted to deny the Resurrection of Jesus Christ. The theory behind it all has an origin in highly flawed argumentation, apparently engineered for the purpose of undermining the faith once for all delivered to the saints.
