The Way relies on Wierwille's teachings, principles and research for its interpretation of the Bible. The Way uses his oral and written teachings to learn how to apply these research keys and principles. According to Wierwille, only the New Testament epistles apply to Christians today, given the Gospels belong in the Old Testament. The Way believes that the Bible shows Jesus Christ is the Son of God, but not God the Son. Wierwille in turn argued that the doctrine of the Trinity and the deity of Christ were introduced to Christianity by pagan converts during the third and fourth centuries.
