The Secret Knowledge Fallacy occurs when knowledge is claimed that is only given to a certain person or group of persons, and there is no way that anyone else can check it out this secret knowledge.
Gnosticism taught secret knowledge that only special people could know.
Sandy: “Evolution is true. Science says so.”
Rocky: “I would like to see the evidence of that. We have talked about this, but you never show me any conclusive evidence. I have heard from others that all the so-called evidence is based on assumptions. If you take away the assumptions, the evidence goes away too.”
Sandy: “The only reason I don't show you the evidence is because only scientists can understand the evidence. You just have to trust them like I do.”
Sandy: “You are claiming that God reveals to you that the Bible is His Word without error, and then He speaks to you through the Bible? That’s secret knowledge. I can’t check it out.”
Rocky: “On the contrary, it is available to every person. Here is how you check it out. Just open your mind to Jesus Christ, sincerely, with respect, a will to obey Him, and persistence. Pray—just tell Him that you want Him to set you free from sin and you want to have the power to obey Him. You want to be cleansed. Ask Him to teach you and lead you. He will reveal the same things to you.”
Sandy: “I’m not going to do that. I’m not having God telling me what to do.”
