doctrinal meaning in religion
Doctrine is a set of accepted beliefs held by a group. In religion, it is the set of true beliefs that define the parameters of that belief system. Hence, there is true doctrine and false doctrine relative to each belief set. In Christianity, for example, a true Biblical doctrine is that there is only one God in all existence (Isaiah 43:10; 44:6, 8). A false doctrine is that there is more than one God in all existence.
