i’ve never heard of this practice before, and it’s fascinating.
fun fact though (since i am a fan of linquistics and typography and such): jesus wouldn’t have been a capitalized pronoun user because capitalization wouldn’t be invented for over a thousand years after his death. and, he would’ve been speaking aramaic, which never developed a bicameral script in the first place. unless of course we’re to assume that he (and presumably his god dad) ghost-wrote the king james bible i guess and they wanted to update their pronouns with these newfangled upper and lower case letters.
you’re not alone in liking em, i think they’re cute. and congrats!
