IT talks about the various religions still around in the Middle East that aren't Jewish, Christian or Mohammedan
Like the Druze, the Alawites, the Mandaens, the Yazidis, the Zoroastrians, the Samaritans etc.
ive heard of the last 3 but not the first 2- some folks try claiming that Zoroastrians predate all religions and that religions take their cues from that religion- however- it certainly didn’t predate Adam and Eve and their descendants who all worshiped God and the Savior even though they didn’t know him as Messiah then- They knew him as the coming redeemer-
