How did the Trinity Doctrine Develop

Excerpt taken from the Trinity Bochure in the chapter, "How did the Trinity Doctrine Develop?":    

"THROUGHOUT the ancient world, as far back as Babylonia, the worship of pagan gods grouped in threes, or triads, was common. That influence was also prevalent in Egypt, Greece, and Rome in the centuries before, during, and after Christ. And after the death of the apostles, such pagan beliefs began to invade Christianity.

    "Historian Will Durant observed: "Christianity did not destroy paganism; it adopted it. . . . From Egypt came the ideas of a divine trinity." And in the book Egyptian Religion, Siegfried Morenz notes: "The trinity was a major preoccupation of Egyptian theologians . . . Three gods are combined and treated as a single being, addressed in the singular. In this way the spiritual force of Egyptian religion shows a direct link with Christian theology." Thus, in Alexandria, Egypt, churchmen of the late third and early fourth centuries, such as Athanasius, reflected this influence as they formulated ideas that led to the Trinity. Their own influence spread, so that Morenz considers "Alexandrian theology as the intermediary between the Egyptian religious heritage and Christianity."

  "In the preface to Edward Gibbon's History of Christianity, we read: "If Paganism was conquered by Christianity, it is equally true that Christianity was corrupted by Paganism. The pure Deism of the first Christians . . . was changed, by the Church of Rome, into the incomprehensible dogma of the trinity. Many of the pagan tenets, invented by the Egyptians and idealized by Plato, were retained as being worthy of belief."

  "A Dictionary of Religious Knowledge notes that many say that the Trinity "is a corruption borrowed from the heathen religions, and ingrafted on the Christian faith." And The Paganism in Our Christianity declares: "The origin of the [Trinity] is entirely pagan."    "That is why, in the Encyclopædia of Religion and Ethics, James Hastings wrote: "In Indian religion, e.g., we meet with the trinitarian group of Brahma, Siva, and Visnu; and in Egyptian religion with the trinitarian group of Osiris, Isis, and Horus . . Nor is it only in historical religions that we find God viewed as a Trinity. One recalls in particular the Neo-Platonic view of the Supreme or Ultimate Reality," which is "triadically represented."'
