Petar Nenadov has a very thoughtful post at the Gospel Coalition, entitled “What We Lose When We Collapse the Four Gospels Into One.”
Consider this:
As a father, I see how most resources for young children don’t teach them to read entire books of the Bible, especially when it comes to the Gospels. Children’s books about Jesus tell stories without saying which Gospel account they come from. Books that helpfully summarize the whole Bible, such as The Jesus Storybook Bible or The Biggest Story, collapse the four Gospel accounts into one as well. They don’t explain how Matthew, Mark, Luke, and John differ from and complement one another.
So what do we lose when we collapse the four Gospels into one? I believe we lose at least three things: the author’s unique perspective, the artistry of the story, and the apologetic of the life of Jesus.
If you’re looking for a children’s resource that does not do this, you may find Mark’s Marvellous Book by Alan Mann a great place to start.
Nenadov’s post has much useful insight. Check it out!
