Remember, Noah is a galaxy brain atheist that thinks all Christian denominations are Catholic because he has a shakier grasp on history than an Assassin's Creed game.Spoony's rampant anti-theism is one of the more entertaining things about him because of how bull-headed he is about it while demonstrating all the knowledge of a 14 year old euphoric atheist on Reddit.
The only things he really knows about religion is what's fed to him through popular culture, and even then he takes the most extreme reading into it.
I mean, before he was shown his own grave, he asked the spirit to show him a death that people cared about and was shown Bob Cratchit's family mourning Tiny Tim which filled Scrooge with remorse, with the implication is that Scrooge himself caused Tiny Tim to die. Yes, the reveal that he also died makes him change his ways, but it's because Tiny Tim's death was paired with his that he resolves to change his ways so that Tiny Tim could live too.
Not to mention, a cursory glance at Wikipedia will tell you that Dickens disliked Catholicism. I don't know where he gets the idea that the story somehow represents the Catholic Church.
