“The Antichrist must be understood as a spiritual phenomenon. Why will
everyone in the world want to bow down to him? Obviously, it is because there is something in him which responds to something in us — that something being a lack of Christ in us. If we will bow down to him (God forbid that we do so!), it will be because we will feel an attraction to some kind of external thing, which might even look like Christianity, since ‘Antichrist’ means the one who is ‘in place of Christ’ or looks like Christ.”

-Fr. Seraphim Rose, “Raising the Mind, Warming the Heart”
