Theological inquiry: “What’s the True definition of a Cult? How does a person explain Christianity is NOT one?”
There are primarily two-types of cults but the one most prevalent in America are Christian Cults. A Christian Cult is an organization that adds anything to the Gospel of Jesus Christ relevant to salvation by “faith alone.” The Scriptures teach us that man can do NOTHING to earn his salvation or righteousness (a right standing) with God the Father; God Himself did the work completely on the Cross and it is only by believing in what Jesus Christ did for us at Golgotha that we can find forgiveness of sin and righteousness with God and the receiving of the indwelling Holy Spirit (John 3:16; John 14:6; Ephesians 1:13).
Christian Cults always deny the sole-sufficiency of Jesus Christ as God as having made atonement for sin. Some cults require attendance at a “mass”- one form of a works salvation; some require baptism; some require speaking in an ecstatic utterance; some include a man-made deity like Joseph Smith + Jesus; some deny the Trinity and consider Jesus a created brother of Lucifer; others deny the deity of Jesus Christ…on and on it goes…but a cult can always be identified by the demonic equation of “Jesus + something” in order to achieve or “earn” salvation.
