"No Apostle would have dreamed of thinking that there are three divine Persons"
(Emil Brunner, Christian Doctrine of God, Dogmatics, Vol. 1, p. 226).
"Theologians agree that the New Testament also does not contain an explicit doctrine of the Trinity"
(Encyclopedia of Religion, Vol. 15, p. 54).
"The New Testament writers...give us no formal or formulated doctrine of the Trinity, no explicit teaching that in one God there are three equal divine persons.... Nowhere do we find any Trinitarian doctrine of three distinct subjects of divine life and activity in the same Godhead"
(Fortman, The Triune God, pp. xv, xvi, 16).
"Neither the word Trinity nor the explicit doctrine appears in the New Testament"
(The New Encyclopedia Britannica, 1985, Vol. 11, p. 928).
"As far as the New Testament is concerned one does not find in it an actual doctrine of the Trinity"
(Bernard Lohse, A Short History of Christian Doctrine, Philadelphia: Fortress Press, 1966,
p. 38).
"The New Testament does not contain the developed doctrine of the Trinity"
(The New International Dictionary of New Testament Theology, ed. Colin Brown, Zondervan, 1976, Vol. 2, p. 84).
"The Bible lacks the express declaration that the Father, the Son and the Holy Spirit are of equal essence"
(Karl Barth, cited in the New International Dictionary of New Testament Theology, above).
"Jesus Christ never mentioned such a phenomenon, and nowhere in the New Testament does the word Trinity appear. The idea was only adopted by the Church three hundred years after the death of our Lord"
(Arthur Weigall, The Paganism in our Christianity, G.P. Putnam and Sons, 1928, p. 198).
"Primitive Christianity did not have an explicit doctrine of the Trinity such as was subsequently elaborated in the creeds"
(New International Dictionary of New Testament Theology, Vol. 2, p. 84).
"The early Christians, however, did not at first think of applying the TRINITY idea to their own faith. They paid their devotions to God the Father and to Jesus Christ, the Son of God, and they recognized the...Holy Spirit; but there was no thought of these three being an actual Trinity, coequal and united in One"
(Arthur Weigall, The Paganism in Our Christianity, p. 197).
"At first the Christian faith was not Trinitarian…It was not so in the apostolic and sub-apostolic ages, as reflected in the New Testament and other early Christian writings"
(Encyclopedia of Religion and Ethics, ed. James Hastings, 1922, Vol. 12, p. 461).
"The formulation ‘One God in three Persons’ was not solidly established, certainly not fully assimilated into Christian life and its profession of faith, prior to the end of the 4th century.... Among the Apostolic Fathers, there had been nothing even remotely approaching such a mentality or perspective"
(New Catholic Encyclopedia, 1967, Vol. 14, p. 299).
"Fourth-century Trinitarianism did not reflect accurately early Christian teaching regarding the nature of God; it was, on the contrary a deviation from this teaching"
(The Encyclopedia Americana, p. 1956, p. 2941).
"The New Testament gives no inkling of the teaching of Chalcedon. That council not only reformulated in other language the New Testament data about Jesus’ constitution, but also reconceptualized it in the light of the current Greek philosophical thinking. And that reconceptualization and reformulation go well beyond the New Testament data"
(A Christological Catechism, Paulist Press, p. 102).Taken From: http://focusonthekingdom.org/articles/trinity.htm
