Well, since there are ten sefirot, you need to find a word which indicates God is ten, right? or you can add in the shechina as a female emanation, plus abba and you get 12, so God is 12. If you add in the original 1, you get 13 so that proves (proves...ha) that God is 13, not love or one, but 13. Uh oh, but if we add in the "one" then we have to add in the "love", right? So God is 14. God is also "Lord." No we are up to 15! God is also truth, and "I am" so that's 17. And isn't God also the word? 18! Shocking gematria which worries me to the core.
See, the existence of these other concepts isn't a contradiction to the idea that God is one. The only "certain Jews" who would find this unsatisfying would be Christians.
