There is no more fundamental biblical imperative than that of avoiding idolatry. St. Paul, recalling the first commandment—“Thou shalt have no other gods …” (Ex. 20:3)—centrally links human unrighteousness with our worshipping and serving “the creature more than the Creator” (Rom. 1:25). Milton’s Paradise Lostoffers powerful glimpses of idolatry’s operations and effects—psychological, theological, and cosmological.
