In the course of time, then, the Father forsooth was born, and the Father suffered, God Himself, the Lord Almighty, whom in their preaching they declare to be Jesus Christ. We, however, as we indeed always have done (and more especially since we have been better instructed by the Paraclete, who leads men indeed into all truth), believe that there is one only God, but under the following dispensation, or ????????? , as it is called, that this one only God has also a Son, His Word, who proceeded from Himself, by whom all things were made, and without whom nothing was made.

This book presents a critical evaluation of the doctrine of the Trinity, tracing its development and investigating the intellectual, philosophical and theological background that shaped this influential doctrine of Christianity. Despite the centrality of Trinitarian thought to Christianity and its importance as one of the fundamental tenets that differentiates Christianity from Judaism and Islam, the doctrine is not fully formulated in the canon of Christian scriptural texts. Instead, it evolved through the conflation of selective pieces of scripture with the philosophical and religious ideas of ancient Hellenistic milieu. Marian Hillar analyzes the development of Trinitarian thought during the formative years of Christianity from its roots in ancient Greek philosophical concepts and religious thinking in the Mediterranean region. He identifies several important sources of Trinitarian thought heretofore largely ignored by scholars, including the Greek middle-Platonic philosophical writings of Numenius and Egyptian metaphysical writings and monuments representing divinity as a triune entity.
