There are many religions (Groups) who make truth claims, claims that are absolute in nature. Does this not shut the door to further learning and understanding, does this not make people stop a continuation of the quest for knowledge? What more does anyone need to know, once they believe they have the truth (Note: I say believe here, and not "Knowing" the truth) I would think that when you really know something, you can also demonstrate what you know factually. I have yet to come across any believer who can demonstrate their beliefs and ground them on facts. This is because of the subjective nature of belief itself, which is a cause for experiential information only.
