Few of us are Essene, or members of an “esoteric order,” so your source does not really applying.
Nazarene, however you spell it, does not come off as polite. But I can’t bring bring myself to call Mormons Saints or Bruce Jenner a woman. I just don’t call it being polite.
My “source” is polite discourse, and your scriptures. From the source:
“He shall be called a Nazarene.” ~Matt 2:23
If you don’t want to be called a follower Yeshua of Nazareth, call yourself whatever you want.
I guess you’re playing ‘devil’s advocate’, if you don’t understand ‘Nazarene’.
