So to begin to show you the baselessness of your assumptions, we need to start with deciding if God is rational.
By definition, and by context, we conclude that rational things can be explained by logic or reason.
1) God is infinite/eternal. This defies logic and reason, because there is nothing in this world that exists or existed that is/will be infinite.
2) God is perfection/flawless in every conceivable way. This also defies logic and reason, because there is nothing in this world that we can say is objectively perfect.
3) God is All Knowing. This also defies logic and reasoning (by our definition of the word).
So, either our understanding of logic and reasoning is limited to the point where we can't explain the rationality of God (my take on this). Or this does not make God rational (your take on this, and subsequently, you believe that because God isn't rational, by default He should be irrational).
Now, if we extend this a bit further and decide if God is irrational.
By definition, and by context, we conclude that irrational things can't be explained by logic or reason.
1) God is One. This defies irrationality in its most primal form. 1 is unique and indivisible.
2) The fact that God is perfection in every conceivable way means there is some form of pattern, symmetry, form (call it whatever you want), so advanced that it simply can't be considered, by definition, random or illogical. We have never found a context where irrationality leads to something even close to perfection, let alone perfection itself.
3) God is All Knowing. Stemming from God's perfection, He would have a limitless and depthless knowledge of every single fact. So, whereby we humans are limited by senses amongst other things, God being All Knowing can't be considered irrational.
So, this negates God from being irrational as well.
Which leads me to what I was saying in my original post-God is neither rational nor irrational. And this brings me onto another point as well, even the terms of rational and irrational are just a culmination of our sensory experiences. If God transcends all of these experiences, then we can't place Him into either category. My personal belief on the situation is that God is simply too great for human understanding, and to be able to explain an unquantifiable supreme being using logic and reason doesn't make Him irrational, or conversely, the lack of irrationality doesn't make him rational. QEdoubleD.
Using this I can also make a case for the Flying Spaghetti Monster. Just watch.
By definition, and by context, we conclude that rational things can be explained by logic or reason.
1) Flying Spaghetti Monster is infinite/eternal. This defies logic and reason, because there is nothing in this world that exists or existed that is/will be infinite.
2) Flying Spaghetti Monster is perfection/flawless in every conceivable way. This also defies logic and reason, because there is nothing in this world that we can say is objectively perfect.
3) Flying Spaghetti Monster is All Knowing. This also defies logic and reasoning (by our definition of the word).
So, either our understanding of logic and reasoning is limited to the point where we can't explain the rationality of Flying Spaghetti Monster (my take on this). Or this does not make Flying Spaghetti Monster rational (your take on this, and subsequently, you believe that because Flying Spaghetti Monster isn't rational, by default He should be irrational).
Now, if we extend this a bit further and decide if Flying Spaghetti Monster is irrational.
