Across the country, religious leaders whose politics fall to the left of center, and who used to shun the political arena, are getting involved — and even recruiting political candidates — to fight back against President Trump’s policies on immigration, health care, poverty and the environment.

Some are calling the holy ruckus a “religious resistance.” Others, mindful that periodic attempts at a resurgence on the religious left have all failed, point to an even loftier ambition than taking on the current White House: After 40 years in which the Christian right has dominated the influence of organized religion on American politics — souring some people on religion altogether, studies show — left-leaning faith leaders are hungry to break the right’s grip on setting the nation’s moral agenda.

Frustrated by Christian conservatives’ focus on reversing liberal successes in legalizing abortion and same-sex marriage, those on the religious left want to turn instead to what they see as truly fundamental biblical imperatives — caring for the poor, welcoming strangers and protecting the earth — and maybe even change some minds about what it means to be a believer.
