Query: A "Must Read" for Spirit-filled Christians

This book is a classic in Eastern Orthodox theology which has been reviewed in detail elsewhere since it's publication in English in 1957. The only thing that I would add is that I believe this book is absolutely essential for Pentecostal/Charismatic Christians. Western Latin theology is inadequate in the light of a church operating in the praxis of the grace and gifts of the Holy Spirit. The theology and doctrine explained in this book create the foundation upon which Penecostalism can easily rest. Don't be afraid to find your spiritual home; it is in the East.
