Thanks to Nick’s post here, I got a hold of this little gem for cheap: less than $5! I’ve had somewhat of an interest in the origins of the Gospels since listening to Mark Goodacre’s lectures at the NT Pod.
David Alan Black’s little book argues for the traditional understanding of the Gospel origins (Matthew -> Luke -> Mark -> John). I’m somewhat skeptical, but it should be a good, quick read nonetheless. On a slightly related note, I learned that Black is right up the road from me at SEBTS, which is pretty neat.
