Judaism is not a religion of blind obedience. Indeed, astonishingly in a religion of 613 commandments, there is no Hebrew word that means “to obey”. When Hebrew was revived as a living language in the nineteenth century, and there was need for a verb meaning “to obey,” it had to be borrowed from the Aramaic: le-tsayet. Instead of a word meaning “to obey,” the Torah uses the verb shema, untranslatable into English because it means  to listen,  to hear,  to understand,  to internalise, and  to respond. Written into the very structure of Hebraic consciousness is the idea that our highest duty is to seek to understand the will of God, not just to obey blindly. Tennyson’s verse, “Theirs not to reason why, theirs but to do or die,” is as far from a Jewish mindset as it is possible to be. (Rabbi Lord Jonathan Sacks, "The necessity of asking questions (Bo 5777)," The Times of Israel, February 3, 2017.)And all this time the leaders of the COGs told us to obey the commandments and yet Biblical Hebrew did not even have a word to meaning "to obey." Clearly those of us who chose to adopt certain Jewish practices thinking that this the correct way to be a Christian had little idea of what we were dealing with.
What were we doing thinking we understood these things? HWA and his imitators took various Jewish practices without understanding the religion. We should just leave the Jewish religion alone and respect it by letting the Jews observe it without us clumsily and ignorantly imitating a few aspects and practices of their religion while rejecting whatever the COG leaders decide does not need to be observed. Clearly the COGs are dealing in things without proper or respectful understanding.
We should abandon the cultural appropriation of aspects of Judaism that Armstrongism so often promotes.
