The Parable of the Vineyard Workers conveys truths about mathematical logic unknown at the time of Christ. In a mere sixteen verses at Matthew 20:1-16, Jesus explains surprising truths about infinity, zero, and set theory. It would take nearly 20 centuries before mathematicians caught up. [Emphasis added]
Only in set theory is it true that "the last will be first, and the first last," as stated by the conclusion of the parable. Outside of set theory that statement ostensibly appears to be false.
Only if infinity exists can a master pay everyone the same wage, no matter how hard or little they work. Infinity is synonymous with God.
The existence of infinity in turn implies the existence of zero, based on the inability to diminish infinity by anything more than zero. Zero -- the zero difference between the "wages" paid, and the jealousy that results -- is synonymous with the lack of God in this story.
A silver lining to the parable is how it demonstrates that communism can create more jealousy than capitalism does, through the jealousy of those who work less and yet get paid as much.
