The anti-christ is not one person. He is a group of people. They mark themselves with the mark of the beast – by cutting the foreskin off their dicks. Not only does this identify them, it also makes mockery of God, who created man to his image, which means God himself is unmutilated. Bbut God also commanded the humans to multiply, for which penis is necessary, so by cutting off their foreskins, the anti-christ makes direct mockery of God and makes himself and his minions identifiable.
