speaking of faith ...
... it is an act of faith to believe that this absolutely, undisputable, fundamental doctrine of true Christianity took theologians some four centuries to develop in full and the secular power of the Roman empire to affirm.
Not exactly true. It might have taken that long to finalize, but it had been around since the OT. And besides, I believe the Society is STILL developing and changing its many theories that come and go like the wind. Bit of a double standard there.

The Trinity in the Bible: Elemental Trinitarianism is evident throughout the Bible
While the Jehovah's Witnesses are correct in stating that the word “Trinity” is not found in the Bible, neither is the word “monotheism” so its absence has no bearing on whether the underlying basis for Trinitarianism exists in the Bible. Careful objective study of the Bible reveals strong scriptural support for recognizing by logical necessity the existence of a triune God - not three Gods, but one God Almighty existing in three hypostasis (Persons) who share the one divine essence. Jesus Christ was sent in part to reveal and explain this threefold nature of God.
Early theologians who strove for a deeper understanding of the doctrine, as well as those of the Middle Ages and modernists, whether Catholic, Protestant or independent, recognize in Scripture an elemental Trinitarianism (Catholic Encyclopedia, 295).
It is clear on one side that the dogma of the Trinity in the stricter sense of the word was a late arrival, a product of centuries’ reflection and debate, it is just as clear on the opposite side that confession of Father, Son, and Holy Spirit - and hence an elemental Trinitarianism - went back to the period of Christian origins. Contemporary studies on the ancient Christian creeds have done much to bring this out.” (ibid., 300)
J.N.D. Kelly attests that “[s]trictly triadic formulas and the triadic frame of mind so clearly mark at least later NT compositions, that the exegete and the historian must recognize a quasi-independent Trinitarianism coexisting with the purer and simpler forms of NT Christology” (ibid., 300). Among the earliest Christians there was “… consistent worship of God in a Trinitarian pattern and the practice of baptism into the threefold name of God” (Encyclopedia of Religion, 54).
18) The Trinity in the Old Testament
While some downplay references to the Trinity in the Old Testament, many Bible scholars find implicit evidence and foreshadowing of God’s triune nature even if the early Israelites failed to pick up on it. The fact that such evidence is limited is immaterial because the triune God was subsequently and intentionally revealed to man by and through Christ, and better understood in the centuries that followed. This progressive revelation was the Almighty’s prerogative, and reasonable in light of the polytheistic pagan nations surrounding Israel at that time. It was necessary to contrast Israel’s polytheistic, many-god worshipping neighbors with a monotheistic God rather than a triune-natured God which could be confused with tritheism, the worship of three Gods. It was Jehovah’s intent to distinguish Himself from false pagan idols.
Though the doctrine is not developed in the Old Testament, it is implicit in the divine self-disclosure from the very beginning, …in a very rudimentary form. This is found not only in isolated passages but interwoven in the entire organism of the Old Testament Revelation. (New Bible Dictionary, 1298)
The mystery of the Holy Trinity was not revealed to the Chosen People of the OT. On account of the polytheistic religions of Israel’s pagan neighbors it was necessary for the teachers of Israel to stress the oneness of God. In many places of the OT, however, expressions are used in which some of the Fathers of the Church saw references or foreshadowing of the Trinity. The personified use of such terms as the Word of God [Ps 32(33.6] and the Spirit of God (Is 63.14) is merely by way of poetic license, though it shows that the minds of God’s people were being prepared for the concepts that would be involved in the forthcoming revelation of the doctrine of the Trinity. (Catholic Encyclopedia, 306)
Early theologians saw semblances of the triune activities of God - wisdom, word and spirit - embryonic members of the Trinity, and disclosure of the Trinity in the appearance of the three men to Abraham (Genesis 18) (Oxford, 1207).
The earliest foreshadowing is contained in the narrative of the creation, where Elohim is seen to create by means of Word and Spirit (Gn. i. 3). Here we are for the first time introduced to the Word put forth as a personal creative power, and to the Spirit as the bringer of life and order to the creation. There is revealed thus early a threefold centre of activity. God as Creator thought out the universe, expressed His thought in a Word, and made His Spirit its animating principle, thus indicating that the universe was not to have a separate existence apart from God or opposed to Him.
It is thought that Gn. I. 26 (‘And God said, Let us make man in our image and after our likeness’) implies that a revelation of the Triune God had been given to man when first created, in as much as he was to be given the divine fellowship, but that the consciousness was afterwards lost with the loss of his original righteousness.
