In commemoration of one hundred years of the Pentecostal movement (1906-2006) Possibly the most globally significant element in the revival of charismatic Christianity worldwide is the startling and sustained growth, over a significant period of time, of the Afro-Caribbean Pentecostal Churches. In this scholarly and communicative study, Dr Lionel Etan-Adollo examines the origins of the Pentecostal movement, traces its development through an informed examination of practical, social, economic, environmental and spiritual micro and macro factors, and sketches a future path for sustained and functional future development of Pentecostalism with particular reference to its Afro-Caribbean context. Dr Lionel Etan-Adollo works as a Senior Management Consultant, a Project Management Professional (PMP) and much more. He has worked on global projects and has travelled as far as Australia, US, Africa and many countries in Europe, and has had the opportunity to visit, worship and study the leading Churches where he has been. This is his spiritual passion and part of his work with God. He has completed post-graduate and doctoral degrees in Theology and Biblical Studies amongst several others. Presently, he is pursuing another doctoral degree in Oil and Gas Law and Policy.
