God the Father is referred to as God more than 1300 times in the New Testament alone, which forms only 25% of the Bible. References to Jesus as God are a couple or very few at best and are contextual misinterpretations or later interpolations.
Sir Anthony Buzzard has a very well written and useful book The Doctrine of the Trinity: Christianity’s Self-Inflicted Wound.
Sir Anthony Buzzard states in the very beginning of this debate that Unity of God is a simple and easily comprehensible teaching, yet very elegant in my opinion, he stresses that Trinity is an unnecessary complexity. If our Christian readers become Muslims, they will find that the Islamic creed, “There is no god but Allah, and Muhammad is His Prophet,” is very simple yet elegant!
The Unitarians build their case on what is central and fundamental and explain away allegoric and peripheral in light of that and the Trinitarians do the exact opposite and no wonder their teachings give rise to countless contradictions and absurdities, some of which are highlighted in the articles linked below. One I would mention here, a literal son, who is co-eternal with his Father, as the Trinitarians will have us believe, is logically and philosophically, simply silly. The Father has to at some point in time father the literal son and predate him, otherwise the son is literally not a son! Additionally, even if Jesus was magically eternal before, when he died for three days and three nights by the Trinitarian, childish counting, he is not eternal anymore. The understanding of what the debaters are doing is certainly in light of a profound verse of the Holy Quran, from Sura Aal-e-Imran, as Sir Anthony Buzzard focuses on central and fundamental and Drew Ayers like any other Trinitarians obsesses over what is ‘susceptible of different interpretations.’ The Quran says:
He (Allah) it is Who has sent down to thee (Muhammad) the Book; in it there are verses that are decisive in meaning — they are the basis of the Book — and there are others that are susceptible of different interpretations. But those in whose hearts is perversity pursue such thereof as are susceptible of different interpretations, seeking discord and seeking wrong interpretation of it. And none knows its right interpretation except Allah and those who are firmly grounded in knowledge; they say, ‘We believe in it; the whole is from our Lord.’ — And none heed except those gifted with understanding. (Al Quran 3:8)
Trinitarians choose to obsess over Jesus and God the Father but seldom or infrequently trouble the Holy Ghost. In their obsession to the person of Jesus of Nazareth, the Trinitarian apologists chose to read the Triune God, every time word God is mentioned in the Old Testament and for 2000 years before Jesus, none of the Jews ever read the word in Triune terms and understood only one God, who is God the Father, in the later Trinitarian Christian understanding.
