This book offers a thorough philosophical exploration of the doctrine of the Trinity. It outlines how early Christian debates led to the recognition of the Father, Son, and Holy Spirit as equally divine while maintaining monotheism. Drawing on contemporary metaphysical tools, it shows how Trinitarian claims about one substance, one nature, one power, and one God can be maintained without lapsing into either modalism or tritheism. It also addresses the question of the Trinity s truth, presenting a novel a priori argument that bases the necessary existence of the Trinity on perfect love.
Written for advanced students and scholars in philosophy of religion and theology, it aims to meet both historical and systematic concerns. By reconciling classical doctrines like divine simplicity with a fully developed trinitarian structure, this book contributes to ongoing debates in analytic theology, reveals fresh interfaith dialogue possibilities, and provides an original approach to understanding why the Trinity is central to Christian thought.
The Coherence and Truth of the Trinity - A Philosophical Exploration is essential reading for all scholars of the philosophy of religion, especially those focusing on the philosophy of Christian doctrine.
