Originally published in 2007, Mac Deaver’s book, The Holy Spirit (Center of Controversy – Basis of Unity), had sold out. We are very pleased to say that, thanks to the great work of our friend, Stephen Bradd, the book is available again. It is a slightly updated edition, but essentially the same in content. Paperback and Kindle editions can be ordered at Amazon. This is the first Biblical Notes book to be offered in digital format, and we hope to make others available in the future. This book gives historical background to the controversial issue of the Holy Spirit in the church of Christ in the last half of the twentieth century to the present.
