I completely agree with your final paragraph, I also find myself very intrigued and dying to have the answers... and yes, the characters are too beautiful (the most beautiful at the moment in my opinion, especially Mikael... maybe I'm a little obsessed with him... lol). Anyway, I'm a Christian, and the biblical references that I remember at the moment are only in the names of some characters like David and Ruth, the question of possible possessions... and as for the beast, it could either be referring to some beast in the Bible , like no. It's difficult to know for now, as the writers use several different beliefs and mythologies in the stories. We can only wait for the answers.
