How pleasantly this book surprised me! Tozer is very orthodox in his Christianity (I most certainly am not), yet he is able to explain some of the more difficult and abstract theology of Christianity very clearly, coherently, and without condescension. The Trinity is a doctrine that is accepted yet no one really understands. I thought perhaps this was a new phenomenon, but reading religious history, it is the one thing over millennia that comes back as too much nonsense for non-Christians and haunting the church in cyclical outbreaks of "heresy." Three is a universally important number in religion: Brahma, Vishnu, Shiva; creation, preservation, destruction; Heaven, mankind, earth; dharmakaya, samboghakaya, nirmanakaya; past, present, future. Groups of three are not objectionable archetypes in religion. It is obfuscatory statements and creeds and swearing loyalty to something the people advancing the theory can not explain. In my formal religious education it was never explained to me. I certainly asked. As I have found usual, it was when I went to another tradition that things started making sense. Studying and practicing Buddhism, one of many trinities is the "trikaya." Kaya is Sanskrit for 'body.' These kayas are the means that the enlightened state/buddhanature manifests. It was easier for me to see three 'bodies' of a singular essence than 'persons.' A body can be alive or dead, whole or partial, many states in which it is a body. A person is a combination of personality, social expectations, and a body. A body may be more than one 'person'. It is much more difficult to spread a person over multiple bodies.
For as good as Tozer's presentation of the Trinity is, I still have my question: what, exactly, is a "person"?
