By definition, a heresy is an error taught about some fundamental doctrine of the faith. In this work, Dr. Ruckman gives you the history of five major groups and examines the errors they teach about key doctrines of the Christian faith. They are the Church of Christ, the Jehovah’s Witnesses, the Seventh-day Adventists, the Charismatics, and the Roman Catholics. The false teachings of each sect are compared to the clear teachings of Scripture on baptism and regeneration, the Deity of Jesus Christ, the reality of Hell, the relationship of the Old Testament Law to the New Testament believer, the gifts and work of the Holy Spirit, Maryolatry, Communion, and the Church.
