In this book, Dr. Ruckman examines how several sound, Biblical doctrines have been abandoned by modern Christianity for the false doctrines of tradition and apostate scholarship. The Biblical position is contrasted with the heretical teaching of Fundamentalists and Conservatives on the following doctrines: the inspiration and identity of the Scriptures, eternal security, the Rapture of the Church, Old Testament vs. New Testament salvation, the definition of doctrine, the spiritual condition of the Old Testament saints, the Body of Christ, Lordship salvation, spiritual circumcision, remission and redemption, the Kingdom of God and the Kingdom of Heaven, the True Vine of John 15 and the olive tree of Romans 11, and world peace. The author shows how rejecting sound doctrine on these subjects ends in the Great Apostasy of the Body of Christ. (Print Length: 171 pages)
