This was a enjoyable and entertaining watch. The production quality is also very impressive. It has alot of subtle things added that was were either clever or hilarious.
What makes this so great is that this is a good introductory video that you can share with Christian friends or family. It's not too 'aggressive' or boring to scare them from watching.
TLDR. It's a film in the format of an old christian cartoon, or even South Park-like animation. The main character is Satan, substituting in as a Sunday school teacher. He teaches the children about ''3 christian seminary secrets'' involving history, authorship, and jesus. These are things that many preachers keep hidden from the average christian believer, because it would prove the bible as false. Satan has along with him various biblical scholars to explain many points, while an angry "jesus' character hilariously tries to make different excuses to keep the children foolishly believing in him.
