Firstly, trinitarianism does not deny that there is only one God, that is foundational
It doesn't deny there is only one God in
word but in "deed", or more accurately, in theory, it
does. A divine person is a God - more than one divine person would be more than one God. To maintain there is only one God if there is more than one person (who is God) is asking people to give a meaningless assent to a creed. I could recite the phrase "there is only one God but 3 persons" but I cannot actually believe that this God is really one in the same sense that a God who is one person is "one". Since pagan theology is defined by a belief in more than one divine person (gods) how am I to understand T-ism which is also a belief in more than one divine person? Again, the
label "one God", when applied to multiple persons, becomes an erroneous ammendment.
Secondly, trinitarianism also acknowledges the distinction between the Father and the Son
Of course there has to be a distinction between a father and a son - but how can there be a distinction between one God and HIMSELF and still be be thought of as ONE God? If the father and son are both deity, but they are not each other, then what you are DESCRIBING, no matter what you
call it, is more than one God.
Thirdly, Jesus certainly can be the Son of God and also God
Sure he can be - if there is MORE than one God. If not, your doctrine is self-contradicting.
This is why he is said to share in the same nature but is distinct from the Father
Then it would appear the "nature" behind these different persons is the REAL God?
Fourthly, "Father" and "Son" are human terms to make this more understandable and as human terms, they will fall short
This is the usual "escape clause" on the subject. If the prescence of contradiction is apparent, just claim the terms used are inadequate. What if I told you I believed in many Gods, but that these many Gods were "ONE person", and that if that sounded contradictory, the terms in use were simply inadequate, and anyway, the whole thing was a "mystery"? Do you believe it is rational that there could be more than one God who was only one person? Such a proposition is no more absurd than that there is one God who is more than one person. It is the mirror-image of the same equation. Either both are reasonable or both are absurdities.
