Why You Should Believe in the Trinity, by Robert Bowman
The doctrine of the Trinity demonstrates respect for the Bible, rather than trying to make God simple and understandable. The doctrine of the Trinity comes from a respect for Sola Scriptura, that Scripture is the only infallible rule for doctrine, faith and practice.
“If Christianity was something we were making up, of course we could make it easier. But it is not. We cannot compete, in simplicity, with people who are inventing religions. How could we? We are dealing with Fact. Of course anyone can be simple is he has no facts to bother about.” C. S. Lewis C. S. Lewis, Mere Christianity, p. 145. (MacMillan Publishing Company, Inc. New York, 1943, 1945, 1952. (Originally in Beyond Personality: The Christian Idea of God, 1944, p. 19)
“The doctrine of the Trinity was formulated by followers of Jesus Christ to safeguard the good news that in Jesus Christ we encounter God face to face. It was not devised to make God less understandable, or to make God so mysterious that the common people have to depend on clergy and theologians to understand it for them, as the JWs [Jehovah’s Witnesses] charge. Instead, the doctrine of the Trinity was developed out of respect for God’s revelation of Himself. [the Scriptures, OT and NT] The Witnesses’ doctrines about God, Christ, and “holy spirit”, on the other hand, were developed not in order to represent the bible’s teaching more faithfully, but to make God understandable and comprehensible. “ “The choice is therefore between believing in the true God as he has revealed himself, mystery and all, or believing in a God that is relatively simple to understand but bears little resemblance to the true God. Trinitarians are willing to live with a God they cannot fully comprehend. As C. S. Lewis put it: “If Christianity was something we were making up, of course we could make it easier. But it is not. We cannot compete, in simplicity, with people who are inventing religions. How could we? We are dealing with Fact. Of course anyone can be simple is he has no facts to bother about.” [My explanatory comments in brackets.] Robert M. Bowman, Why You Should Believe in the Trinity: An Answer to Jehovah’s Witnesses. Baker Books, 1989, p. 138-139.
Jehovah’s Witnesses (Arianism) and Islam are similar in that they reject the doctrine of the Trinity; which demonstrate that they are man made religions, among other problems of many false doctrines.
Another excellent book on the Doctrine of the Trinity is, The Forgotten Trinity, by James R. White.
Remember an earlier post I wrote, On the Incarnation, the Atonement, and the Trinity and how we see the glory of the true God in the relation of God humbling Himself in the Incarnation and the Atonement of Christ.
