You can explain Trinity by Catechism(Holy Tradition) through mysterious and strained statements. I can bring many verses which directly prove that Jesus was merely human and prophet. The Trinity doctrine has many conflicts which make many Christians to have scanty faith. I think Christianity will be more powerful without that doctrines.
Do you not see conflict in writing!
God is one.
(That is nice)
But,
Father is God.
Son is God.
Holy Spirit is God.
(Three gods!)
And…
Father is not Son(But Son was God so Father should not be God)
Son is not Spirit(But Spirit was God so Son should not be God!)
Spirit is not Father(But Father was God so Spirit Should not be God!)
Ofcourse there are much more conflicts in meaning!
No, once more, there are not three “gods” – one God, three persons. The logic is complicated, but don’t pretend to be able to dismiss it so easily when you haven’t even understood it. I’m not at all surprised you think you can shoot this down with a ton of verses – everyone thinks they can do that – but if you take single verses from the Bible and use them as magic bullets to solve problems, you can prove almost anything. What matters is the cohesive whole that unifies the verses and makes them make sense.
It is similar (but by no means identical) in logic to:
You are one being.
Your mind is you.
Your soul is you.
Your body is you.
Your mind is not your soul.
Your soul is not your emotion.
Your body is not your mind.
A related Duality (two parts instead of three) is already *proven *to exist, for example, in light:
Light is one thing.
Light is a wave.
Light is a particle.
Particles are not Waves.
Waves are not Particles.
By your logic, this would also be inconsistent. Yet it exists! So it is possible to have this reasoning structure and be valid. [Whether God is truly like this is another matter.]
Further, to quote Edward Feser
- The Father is God.
- The Son is God.
- The Holy Spirit is God.
- The Father is not the Son.
- The Father is not the Holy Spirit.
- The Son is not the Holy Spirit.
- There is exactly one God
Is this not an inconsistent set? Not as it stands, it isn’t. For we need to know (among other things) what the force of “is” is in each of these propositions. (Bill Clinton wasn’t all wrong, as it turns out.) If (1) is glossed as “The Father = God” and (2)-(6) are interpreted accordingly, then we would of course have an inconsistent set. But that is not how Trinitarian theologians understand “is” in this context; that is to say, they are not using it to express what modern logicians understand by the identity relation. If instead we interpret (1)-(3) as “The Father is a God,” “The Son is a God,” etc., and (4)-(6) alone in light of the identity relation – so that (1)-(6) are understood to assert that Father, Son, and Holy Spirit are distinct members of a class of “Gods” – then, again (given (7)), we have an inconsistent set. But, again, that is not what Trinitarian theologians mean by “The Father is God,” etc.
So you can see your interpretation is staunchly rejected by theologians on this issue and is indeed flawed because it attempts to replace is with “=” which is not a valid representation of the logic in this case.
Perhaps a quote from Lewis might be better to help elicit understanding:
A world of one dimension would be a straight line. In a two-dimensional world, you still get straight lines, but many lines make one figure. In a three dimensional world, you still get figures, but many figures make one solid body. In other words, as you advance to more real and more complicated levels, you do not leave behind you the things that you found on the simpler levels: You still have them, but combined in new ways – in ways you could not imagine if you knew only the simpler levels.
Now, the Christian account of God involves just the same principle. The human level is a simple and rather empty level. On the human level one person is one being, and any two persons are two separate beings – just as, in two dimensions (say on a flat sheet of paper) one square is one figure and any two squares are two separate figures. On the Divine level, you still find personalities, but up there you find them combined in new ways which we, who do not live on that level, cannot imagine. In God’s dimension, so to speak, you find a being who is three Persons while remaining one Being, just as a cube is six squares while remaining one cube. Of course we cannot fully conceive of a being like that: just as, if we were made so that we perceived only two dimensions in space we could never properly imagine a cube. But we can get a sort of faint notion of it. And when we do, we are, for the first time in our lives, getting some positive idea, however faint, of something superpersonal – something more than a person.
So I hope you at least begin to see how the Christians conceive of God as a Monotheistic Being with multiple Persons, even if it can’t be understood by us anymore than we could truly understand what it would be like to see in Ultraviolet.(Did you expect God to be simple, such that you and I could understand Him?

).
I have not (and don’t really intend to) provide an argument for its veracity, but I hope you will be able to comprehend that what Christians are supporting is not three Gods (or even one God with multiple personality disorder), but rather, a doctrine drawn upon enhanced knowledge of God, yet entirely consistent with its basis of Monotheism. Is it strange? Certainly. Is it consistent with ironclad Christian monotheistic? Yes.
