A primary concern amongst missiologists is presenting the gospel in a way that is culturally relevant without adulterating the essential truths of the message of Jesus. Appropriately contextualizing this message can establish an indigenous Christianity, as opposed to introducing syncretism. In this compendium of presentations and papers, the issue of syncretism is addressed through the lens of our covenant relationship with the Lord. Drawing from interdisciplinary research across continents, Tippett examines the syncretistic religious behaviors eminent at the time of his writing that threatened to fracture this covenant relationship-- from eastern personality cults in India to scientology in Australia, from satanism in the United States to animism in Mexico. With over 20 years of research, Tippett provides timeless insights for a global church burdened with the Great Commission call in an increasingly pluralistic world.
