This is work. We must put in the work of discernment. We must know the rules. We must dust off the hermeneutics textbooks. We must insist on one of the basic rules and that is the rule of context.
All cults trick their followers by wresting verses from their context.
Another rule is Contextual Proximity, which broadens the context rule. For example, an Old Testament book might illuminate Paul's meaning, even though it is written in another language and hundreds of years earlier, because we can be confident that Paul knew it and considered it authoritative. It is also important that we try to understand the biblical world. Background studies in Edershiems' works are helpful in this. How different must be the thought and expression of the East, growing necessarily out of these opposite ways of life and manners.
