One of the best critiques of the biblical doctrine of the Trinity I have read. Sproul first lays the foundation for the concept of the Trinity in the OT and then goes on to expand it in the NT. This subject is not easy to cover as it pertains to the very essence of trying to understand God. In my opinion, the writer handles this subject well and sensitively and also with due reverence.
This book does not claim to be definitive( what book could) but simply to help the reader to a perhaps better understanding. Biblically sound in orthodox Christian doctrine this is another good booklet by this renowned author.
