There is quite possibly no greater threat to the believer than the existence of the apostate. In order to reduce dissonance, the true believer must assume that their own particular system of faith is so obviously true that no open-minded seeker who is fully appraised of the facts can fail to accept it. The apostate represents the real-world disconfirmation of this assumption. It is possible to ascribe the existence of non-believers to several sources – the work of the Enemy, or a deliberate (and thus rebellious) close-mindedness or even, in some cases, non-election. The apostate, however, is in a different class altogether. The apostate is defined as a person who, at one time, fully accepted the dogma and tenets of the particular system, who participated in its rituals, and who defended it from the attacks of unbelievers. However, the apostate at some point reached the conclusion that the system was intellectually bankrupt, and defected from the faith, either for another tradition, or for a system of freethought.Thus, the apostate cannot exist in the worldview of the believer.Rational thought is the true enemy of the believer.
This line of defense usually produces a curious paradox. Most human beings need rational thought in order to function effectively in the secular world. They are thus quite able to effectively apply logic and reason in everyday situations. But, it is important that this light of reason never be brought to bear on one’s own system of belief. The reason for this is not difficult to determine – very few, if any, religious systems can survive a dispassionate, rational dissection. This fact is acknowledged by the believer, usually unconsciously.Complete article here
