Well, since long I believe in the "resurrection" of heresies in different times under a "new" sect or name...before I hadn't found too much about the Nicolaitans or forgot to post it...or...
for me the closest to TF was always Thyatira...or the Carpocracians...todays scholars seem often to be hesitant to say anything specific about a name, if it is "only" found in the Bible or mentioned by the churchfathers (no "outside"/other source)...may be that's why there aren't too many direct quotes of them in the internet answers....I listed some links, which I found very useful...I would like/appreciate to have further input...as for now, I got "tired" in googling more ; )
Anyway..."dear" ol' TF repeats the bad mistakes of the past...they just don't get it...so much for them being spirit-led...ok, but by the wrong/false one...

excerpts from a book...seems to be very good & detailed
