Financing churches using Christian’s contributions seems to be a challenge in many churches today. Changes in the society due to technological effects have exposed believers especially in developing world to modern lifestyles which in turn have resulted to more youth not attending church services. These changes namely social, political, cultural and economical are perceived to have caused unreliability and non directional fluctuation of Christian’s contributions as a main source of fund. This book gives field evidence on source of church finances and its reliability to sustain church operations. It shows how previously different authors thought about reliability and sources of church finances including willingness of contributors. The book explains reliability and sustainability of Christian’s contributions as a major source of fund at Dioceses and at Parish levels. Finally it shows light on the way forward on how churches can focus to sustain their Dioceses and Parishes financially without affecting Christians spiritually.
