The shills hating on you about this, saying "MUH MARK HAS TO LITERALLY BE ON HAND OR FOREHEAD," would also have you believe that a literal woman in the sky is travailing and giving literal birth. Be wary of anyone who tells you they are the ones who know for sure how to interpret the Bible.
Isn't it funny all the "atheists" who criticize Christ interpret the Bible literally? What do we call people who interpret religious texts literally? Oh yeah, extremists.
