What if John wrote first?
In Star Wars: A New Hope, the character Han Solo was confronted by an intimidating bounty hunter, Greedo. In the original cut of the film, Han shot Greedo before things could get out of hand. This fit with the anti-hero arc, Han was the scoundrel with a heart of gold. In later recuts of the film, Greedo shot first. And so in nerd circles, people lament, 'Han Shot First.'
Jesus the Good Shepherd
Mark's Jesus
A common claim in New Testament studies is that Mark's gospel must be first because it apparently contains the least developed understanding of Jesus, but John's gospel was last because it clearly refers to Jesus' divinity.The problem with this is that Mark’s gospel alludes to and presupposes Jesus’ divinity by what it makes plain throughout its pages. The problem is that these assumptions only surface by means of certain allusions. In other words, Mark believes in Jesus’ divinity, but he only expresses this by “telling it slant.”[1]
