Very apropos to your thesis here, is this essay by Gavin Sher that I cite often. https://medium.com/interfaith-now/god-a-most-misunderstood-word-7b99d4491263 In it he writes: "The holiest prayer in Judaism is the Shema, in which the holiest line, affirmed by Jews repeatedly every day, is often translated as ‘Hear O Israel, the Lord is your God, the Lord is One’. Obviously Hebrew is not English and translation can be a subtle thing. A more truthful translation of that holy line would be ‘Hear O Israel, The Lord is your God, the Lord is a Oneness,’ i.e. that ‘God’ is a Unity."

Earlier, he points out that as the Torah has 72 names for God, "Even Hinduism, according to some teachers, doesn’t hold that there are many ‘Gods’ but, like Judaism, takes the many deities to be expressions of different aspects of the One Godhead."
