Ok, this is starting to bug me a little... Is your intention there to mean that God himself is indivisible? Otherwise, the sentence structure breaks apart without the comma.
In either case, I am unable to follow your logic.
My intention is to say that most people say it incorrectly. It's also to state that Wikipedia is wrong. I also incorrectly copy/pasted my original post. That's what I get for posting tired again. Let me clarify:
I pledge allegiance to the flag of the United States of America (natural pause)
and to the Republic for which it stands,
one Nation under God, indivisible,
with liberty and justice for all.
NOTE: There would be FOUR PAUSES when reciting the Pledge… first note that there is no comma after the word “America” but a ‘natural’ breathing pause…
PAUSES would then be…
(1) after the word “America” –
(2) after “stands,” –
(3) after “one Nation under God,” –
and (4) after “indivisible,”.
Most people pause between "one Nation" and "under God" and that's how it's typed on Wikipedia. Just saying, it is incorrect.
