Jesus and Jonah

Jesus and Jonah is J.?W. McGarvey's defense of the historicity of the Biblical account of the book of Jonah based on Jesus' teaching about Jonah-which is the same as His teaching regarding the historicity of the rest of the Old Testament. This would indicate that Jesus either accepts all of it as historical or none of it as historical. Since the New Testament makes it plain that Jesus accepts the Old as historical, McGarvey argues that the denial of the Jonah story makes Jesus either a liar or a fool.
