Are you saying that Abraham had nothing to do with those religions? If so, tell me, do not the muslims believe Mohamad was a decendent of Abraham?Isn’t Jesus a decendant of Abraham? My point is they are all derived in one shape or form from Abraham.And that is part of the OT. Are not the teachings of the OT part of gods word. Yes, they are all cults, just a different shade cf opinion and tradition.
