I have the feeling — ok, more than a feeling — that churches and schools mean very different things when they use the word “multicultural”.
Governments and schools use the term to refer to a stifling postmodernist ulcer (excuse the mixed metaphor), one where value judgements about cultures, or even specific aspects of them, is strictly verboten. It is this, not diversity, that I hate. God forbid that I should think diversity a terrible thing.
Churches mean the reality of church unity across lines that other institutions would draw between genders, “races”, ethnicities and classes.
The one says no one has the truth any more than any other. The other says the truth has set us free and now has us, informs us and transforms us.
