This book is a very poor and dishonest attempt to establish the doctrine of the Trinity By James white. He starts by making a case for what the Trinity is, but makes such a poor explanation of it that it can't really even be defended. He lacks understanding of modern scholarship on the philosophy of the Trinity with no references to any of them to explain what exactly his theory is. As he tries to derive it from scripture, it becomes a mess of theological confusion and contradictions. In some cases, identifying Jesus with God would seem like modalism, in others, he does this very thing and says it is Trinitarianism. The reader is left wondering what the Trinity really even is by the time the book is finished. Some sort of mystery that he explains that can't be explained, I suppose.
His exegesis of certain scriptures, while i understand are not meant to be comprehensive and arguing against every interpretation, fail to even mention huge manuscript variants in problem passages, and just seems outright dishonest. One of my main criticisms is the way he straw man's the Unitarian position. He takes the weakest version of an argument (which no Unitarian writers ever even use besides maybe Jehovah's Witnesses), and beats it to death without mentioning the real criticisms provided by them, and even other Trinitarian scholars who disagree with White's case for the Trinity from these passages, or the deity of Christ.
I hoped that reading this book would give me more insight into the Trinitarian worldview from a scholar, but there are many more and much better writers to spend your time studying and researching. I wouldn't recommend this one, I'm afraid.
