You Tube Theology

I received an email about what could be the weirdest misuse of the aorist tense I have ever seen. They claimed that the aorist “having followed” in Matthew 19:28 describes a once for action that was eternally binding, and therefore Judas will be in heaven judging the twelve tribes of Israel. How do people come up with these things, and what lack of humility allows someone to make a claim about Greek that no grammar or commentary would allow?
