E. Calvin Beisner tracked the progress and misunderstanding of the Doctrine of the Trinity from the New Testament, through the ante-Nicene thinkers, and through the multiple difficulties with gnosticism, neo-Platonism, subordinationism, polytheism, Monarchiansm, and finally Arianism and the various forms of each. It is a book, that in my opinion, does a great job contrasting the orthodox Christian understanding of what is taught in the Bible vs. the pseudo-Christian Trinities. It finishes with the final Nicene Creed and the support by section. Overall, I saw it as well written and accurate in its depth. Its readability was easy without sacrificing the profundity of God being the Father, Son and Holy Ghost. I appreciated the author’s tone and respect of other's views but still pointed out why the early Christians put in so much work and clarification so as to properly elucidate their view of the concepts and biblical support for their beliefs. I walked away with a better understanding of the rival thoughts that were actually misunderstandings of other church thinkers and political moves to seize control and influence using some political maneuvering. Again, it was well written and left me with a strong understanding of the historical context and the importance of vocabulary distinctions within each council. I highly recommend picking up this short book and hope you enjoy it as much as I did. ( )
