In Torah it is important to have an idea about what is the main thing and what are  the side issues. Thus monotheism and good midot [to be a mensch] ought to be the foremost in everyone' mind. Monotheism is certainly the command to worship and serve God alone. But it also means to understand that God is completely ''other''.  HE is not  a close relative of people. He does not share any characteristics of people,  for all characteristics He created. He has nothing in common with any physical objects- no form nor substance. He is not composed of ingredients. He is not a composite.
