God would not make it a "complex" understanding of who he truly is.
Let's examine scripture to discuss this statement.
This seems to be the logic progression you're using to arrive at your conclusion:
premise 1. God would not make it a "complex" understanding of who he truly is.
premise 2. All scripture teaches Truth
Inference: Therefore, if an interpretation of scripture suggests that an aspect of God is beyond human comprehension, that interpretation is incorrect, and an interpretation that fits within our own realm of comprehension is more valid.
I propose to you that your first premise can be challenged through scripture.
Job 36:26 Behold, God is great, and we know him not, neither can the number of his years be searched out.
1 Cor 1:21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
1 Cor 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
Deut 29:29 The secret things belong unto the Lord our God: but those things which are revealed belong unto us and to our children for ever, that we may do all the words of this law.
Isaiah 55:9 For
as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
Because of what scripture tells us about the nature of God, it's very difficult for me to accept this notion you seem to be suggesting that if someone claims some aspect of God is beyond our comprehension, then it must not be true. If we really believe that God is greater than us, wouldn't it be rational to accept that aspects of His nature will exceed the scope of our comprehension? Should we really expect that the nature of God should "make sense" to us? If you say "yes," do the scriptures teach that, or do they instead teach that God is greater than our comprehension?
Paul writes: 1 Cor 13:12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
Should it surprise us, then, since not all Truth has yet been given to us, that some aspects of God should remain a mystery?
So I propose to you instead:
premise 1. All scripture teaches Truth
premise 2. It's rational to accept that God may not be fully comprehensible to us
Inference: If the scriptures seem to teach something that we don't comprehend, it may simply be that we can't comprehend it, but it's still rational to believe it.
Now, friend, I am not attempting to "prove" you wrong. What I am suggesting is that you have accepted the statement "God would not make it a "complex" understanding of who he truly is" as infallible truth, and you use that statement as a premise to reach certain inferences in your scriptural interpretations. However, if that statement is not what the scriptures teach about God, it calls any conclusion made using that premise into question. So I am asking you to re-examine your conclusions, discarding the premise that "God would not make it a "complex" understanding of who he truly is," on the basis that such a belief is not what scriptures teach us about God.
Incidentally, even though I believe that we cannot fully understand God, I also believe that the scriptures to provide sufficient explanation for this particular matter, which I can show you if you are interested.
Also, because you seem to be implying that the reason we (Trinitarians) believe that Jesus is God is because scripture has been mistranslated, a word of warning about "the original Greek/Hebrew definitions:" Understanding a dead, ancient language takes a lifetime of study. It's far more complex than simply knowing "the definition" that comes from a concordance. I suggest that you not be quite so quick to dismiss readings of scripture that do not match your own, based solely on "Understand[ing] what words in the original greek or hebrew meant." It is good to learn some Greek and Hebrew, though, primarily because the more you learn about it, the more you realize just how many factors impact on translation that extend beyond simple word definitions.
