The writer of the Book of Ecclesiastes in the Old Testament said that "there is no new thing under the sun" (Eccl. 1:9) and students of church history never cease to be amazed that the same theories and philosophies arise from time to time in the Church of Jesus Christ. The ONENESS doctrines, which, we are told, have come as a result of a present-day "revelation", are, in reality, a revival of old errors, which were propagated and developed during the early centuries of the Christian era. These old discredited theories were rejected then because they were weighed and found wanting - and, since truth and error remain basically the same, the ancient objections to these ancient errors are still effective today. The "new issue" is really a very old issue! The Oneness Doctrines examines this teaching under different headings: 1. The Oneness Teaching. 2. Church History and the Trinitarian Controversy. 3. The Scriptures and the Doctrine of the Trinity. 4. The Baptismal Formula of Matthew 28:19. There are a variety of "Oneness" doctrines (e.g. Jehovah's Witnesses), but for the purposes of this book we are concentrating on the "JESUS-ONLY" types, which are being taught even in some "Pentecostal" circles. They are known as UNITARIAN PENTECOSTALS. Who are they? And what do they believe? The Oneness Doctrines: What Do They Believe? compares the teaching of this group with basic fundamental Biblical doctrine. This eBook is not designed to ridicule or scorn the teaching of those who differ in faith and doctrine, but to examine teaching that claims to either hold to orthodox Biblical Christian doctrine or claim that their movement accommodates Biblical Christianity. Available material was researched and leading people interviewed, where possible. The conclusions drawn in this ebook about the Oneness movements are based on information made available and every effort has been made to present the material as accurately as possible. The battle today is for the mind of men, women and children and we need, more than ever, to keep our attention focused on THE LORD JESUS CHRIST.. "Looking unto Jesus, the Author and Finisher of our faith" (Heb. 12:2).
