Felix Manalo, the founder of the Iglesia Ni Cristo (INC), stands as a pivotal figure in the religious history of the Philippines. His life and work represent a fascinating case study in the emergence and growth of a new religious movement within a complex and dynamic socio-religious context. This book explores Manalo's journey from his relatively humble origins to his leadership of a global religious organization with millions of followers. It examines his theological innovations, his strategies for building and consolidating a strong and hierarchical church structure, and the lasting impact he has had on the religious landscape of the Philippines. We will delve into the historical context in which the INC emerged, analyzing the socio-political dynamics and existing religious traditions that shaped Manalo's vision and the early development of the church. This will include an exploration of the religious diversity of the Philippines during Manalo's lifetime, highlighting the interplay of established Christian denominations, indigenous belief systems, and the growing influence of Pentecostalism. A detailed account of Manalo's early life will shed light on the formative experiences and influences that shaped his religious worldview. The narrative will then trace the evolution of the INC under his leadership, analyzing his methods of organization, expansion, and conflict resolution. The book will also analyze the theological contributions of Manalo, exploring his unique interpretations of biblical texts and the distinctive doctrines that define the INC. Furthermore, it will examine the broader social and political implications of the INC's growth, exploring its impact on Filipino society and its relationship with the state. The book also addresses criticisms and challenges faced by Manalo and the INC, providing a nuanced and balanced perspective. The aim is not to offer a simplistic narrative of triumph but to present a comprehensive account that acknowledges both successes and complexities. Finally, the study will examine Manalo's legacy, analyzing his enduring influence on the INC and the broader religious landscape of the Philippines, considering its continued evolution and global expansion in the decades since his passing. This balanced approach seeks to satisfy the needs of a diverse readership, including scholars of Philippine religious studies, members of the INC, and general readers interested in Philippine history and religious movements.
