For Christians accustomed to anticipating a new heaven and a new earth with “members of every tribe and language and people and nation” (Revelation 5:9), multiculturalism may be perceived to be something wonderful developing in the culture that biblically faithful Christianity can latch on to. On the other hand, where “multiculturalism” is a sloganeering word associated with left-wing social agendas that relativize all cultural values and all religious claims, except for the dogmatic claim that all such values are to be relativized, the word may bespeak a culture diametrically opposed to the exclusiveness of Christian claims.
