Rev. John Whale, Christian Doctrine. “The systematic thought of the Church inevitably involved a further definition of monotheism, an elaboration of the unitary conception of the Godhead….Christian thought, working with the data of the New Testament and using Greek philosophy as its instrument, constructed the doctrine of Trinity in Unity….The popular view of the Trinity has often been a veiled Tritheism.”

Tom Harpur, For Christ’s Sake, p. 81. “What is most embarrassing is trying to prove the Trinitarian doctrine from the NT documents. You simply cannot find the doctrine of the Trinity set out anywhere in the Bible. St Paul has the highest view of Jesus role and person, but nowhere does he call him God. Nor does Jesus himself anywhere explicitly claim to be the Second Person of the Trinity, wholly equal to the heavenly Father. As a pious Jew, he would have been shocked and offended by such an idea. This research has led me to believe that the great majority of regular churchgoers are for all practical purposes Tritheists. That is, they profess to believe in One God, but in reality worship Three. Small wonder Christianity has always had difficulty trying to convert Jews and Muslims. Members of both these faiths have such an abhorrence of anything that runs counter to their monotheism, or faith in the unity of God, that a seemingly polytheistic gospel has little appeal for them.”

Berkhof, Systematic Theology, 1969, p. 89. “The Church confesses the Trinity to be a mystery beyond the comprehension of man. The Trinity is a mystery, not merely in the biblical sense that it is a truth, which was formerly hidden but it now revealed; but in the sense that man cannot comprehend it, and make it intelligible. It is intelligible in some of its relations and modes of manifestation, but unintelligible in its essential nature. The many efforts made to explain the mystery were speculative rather than theological. They invariably resulted in the development of tritheistic or modalistic conceptions of God… The church has never tried to explain the mystery of the Trinity, but only sought to formulate the doctrine of the Trinity in such a manner that the errors which endangered it were warded off.”

Encyclopedia Britannica, 1949, Unitarianism. At the Reformation Servetus was burned at Geneva at the direct instigation of Calvin for the sin of writing (1531) “errors of the Trinity.” [He] first put the issue squarely before the world; “Your Trinity,” he wrote,” is a product of subtlety and madness. The Gospel knows nothing of it. The old fathers are strangers to it. It is from the school of the Greek sophists, that you, Athanasius, prince of tritheists, have borrowed it.

Whately, D.D., Elements of Logic, pp. 375, 6, 1836. “Nor were those who were accounted orthodox altogether exempt from the same fault of presumptuous speculation. ‘Who,’ says Chrysostum, ‘was he to whom God said, “Let us make man,” but he, the Son of God?’ And Epiphanius on the same passage says ‘This is the language of God to his Word.’ Each of these writers it may be observed in representing God under that title as addressing Himself to the Son as a distinct being, previously to the birth of Jesus, approaches very closely to the Arian tritheism”
