As a religious gay man who believes his party has ceded discussion of religion and spirituality to Republicans, Pete Buttigieg, a Democratic candidate for president, is talking about God and sexuality in an unconventional way: He is using the language of faith to confront the Christian right on territory they have long claimed as their own.
Mr. Buttigieg, the mayor of South Bend, Ind., has provoked a backlash from conservatives in the last few days after questioning the moral authority of evangelicals like Vice President Mike Pence who remain silent about President Trump’s personal conduct yet disapprove of same-sex marriages and oppose gay rights.
