The Trinity of God: Saint Augustine Martin Luther and John Bunyan

I have put together a book on the Christian doctrine of Trinity. The book presents three views on the subject, from authors whose writings are in the Public Domain, as designated by Project Gutenberg. Such a book is not otherwise available in this format.
The book gives the buyer possibly the best set of scholarly thought on the Christian doctrine of the Trinity. The customer will enjoy the rich experience from the writings of three “greats” on the subject - Saint Augustine, John Bunyan and Martin Luther. This lets you study, critique and grasp - in a single volume - probably the most important and enigmatic doctrine in Christianity. To this extent, the book is also unique and differentiated.
In summary, this book is unique because:
• The topic begs for authoritative insights
• There’s no other volume like it
