In the case of the Byzantines, did you know that all Christian
  monasteries started off as Epicurean communities? I once
  researched it. I asked, "What happened to the Epicureans?" Well,
  they never left. Emperor Justinian and Empress Theodora, upon
  establishing their territory and Christianizing the Roman Empire
  (the Eastern side 'cause Rome was shit by then), all of the
  Epicureans got a Christian frosting on top. Everything else
  stayed the same for them. No bloodshed, conversion by force like
  you'd expect (at least that I ever read about). They just
  changed flags. Protection of the empire wasn't the worst thing
  to have. They got to keep their lifestyle and it formed the
  basis of Christian monasticism. After the Great Schism, the west
  started going a little differently of course. Scholasticism was
  a uniquely western way of doing things.. liked splitting things
  up. Ended up taking western monasticism in a different
  direction... or a bunch of them really. Anyway, I wouldn't cry
  over the gnostics. The real gnostics were over and done with
  VERY early on in Christianity. Anybody afterwards (11th century
  or whatever) that called themselves gnostics were
  neo-gnostics... picking up some old books and trying to start a
  new thing based on old books. Not really the same. But I'm not a
  fan of the western church stuff. It's weird - i've been agnostic
  for like 15 yrs now I suppose but I guess my exposure with the
  Orthodox biased me. Oh well tongue emoticon == Yeah, because of
  my exposure to the Orthodox, in my mind, I see the timeline of
  things kinda like this. Not exactly, but kinda. So, I see all
  the stuff in Europe and Rome to be political power hungry BS,
  Protestantism as "hey we got this book and we don't need
  historical continuity" and basically, they're playing church.
  That's what I get for searching for roots. I was raised
  Methodist, went church hopping, ALMOST went catholic, then ended
  up going Orthodox for 5 yrs... Got to breath a different
  perspective than BBC history. It was cool. Expanded my
  perspective of history away from event-driven dynamics towards
  historical continuities and discontinuities of peoples. One of
  these days I want to dive into Chinese history and get that kind
  of 'sense' of it that I get with Western Civ. I'm also lacking
  in much Islamic history. In my head, Islam proper ended the
  moment they started slashing instead of educating, around the
  13th century I suppose and DEFINITELY by the Ottoman empire. TO
  me, that's when they lost it and became "this thing they call
  islam" but isn't REALLY Islam. Lost their continuity. Weird way
  of viewing history I suppose. == I mean, the ppl running the
  empire and the bishops were definitely working with each other,
  but they kinda kept their affairs separate but in sync as much
  as could be. Not always of course. But they were big believers
  in something we see as a negative these days: "status quo". They
  lived and breathed status quo for like 900 yrs. Has its downside
  but the upside was an internal peace and even decent relations
  with foreign countries, once diplomacy took place. But it was a
  unique situation in world history. Awesome modern example of
  status quo is
  [1]https://en.wikipedia.org/.../Status_quo_%28Holy_Land... -
  from the 18th century onwards. There's peace and cooperation in
  the holy sites. NOTHING happens new without complete agreement
  among all parties. OF course that means,nothing broken gets
  repaired. BUT, they're not fighting over it. An awkward peace
  but it serves a function. ==
