In Nashville, a crowd of ministers carrying palm fronds occupied the governor’s office during Holy Week, demanding the expansion of Medicaid to cover more of the uninsured. In California and 16 other states, an interfaith network has organized thousands of volunteers to swoop into action when immigrants are arrested or houses of worship are vandalized.

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.
