Intelligence is an umbrella term used to describe a property of the mind that encompasses many related abilities, such as the capacities to reason, to plan, to solve problems, to think abstractly, to comprehend ideas, to use language, and to learn. (WikiPedia) Religion is societal, and is based on teaching and information. It has no relationship to intelligence in general terms. People who are given certain information believe certain things. Those who receive different information may or may not believe the same things. However, belief is related to intelligence only in the sense that it involves processing information.
