There is a common misconception when it comes to the core of monotheism. The ancient declaration of a single deity to most is just that saying that there is one deity not many.
However, this statement goes much much deeper into the core of what that deity is when the wording is looked at properly.
שְׁמַע יִשְׂרָאֵל xxxx אֱלֹהֵינוּ xxxx אֶחָֽד
(The 4 letter name is "x"ed out to show respect)
"Hear, O Israel! Adonai is our God! Adonai is One!"
The declaration of "One" goes deeper than just saying it is a single god. It is a declaration of unity, a grand totality or lets say the grand unification. Yes, the same thing that science is looking for. This can be seen as the totality of Infinity to include all things that the human mind can and cannot comprehend, to include paradox, all thought, everything. For Infinity to be true total infinity there cannot be anything that is not included within it, there is nothing with out it. It is all there is, it is a singularity. ONE.
Think of the implications of such a statement. There is nothing separate from the divine, to include you, me, your shoe and on and on infinitely. Good/Evil everything to include nothing. Many "religious" concepts, dogma, traditions fall apart and become moot under the weight of that kind of meaning.
Think about it.
