That is easy to detail. ask yourself,
- "Are they telling me that all Christian churches are wrong and that they are a special group to whom God alone has given truth?
- Do they attack the diety of Jesus Christ and lower Him to the level of a man, or even raise man to the level of Christ?
- Do they deny that man can be saved by faith in Christ? in other words, do they teach that man can make himself right with God by good works?
- Do they say that their leader, human leader, has new additions to the Bible or even new interpretations?
- Do they distort the Bible's teaching to suit their own particular belief about man,God,the Holy Spirit, heaven, hell, salvation or other vital doctrines?
