Evangelicals see the Bible as the ultimate source of guidance for every aspect of life. But how exactly to apply to that to difficult moral dilemmas isn't always clear.

And this week, as the question of what to do about the plight of refugees from Syria and Iraq in the wake of the Paris attacks has become a national political debate, it's also become a moral question — one evangelicals are divided over.

There's a fierce political debate underway about how the U.S. should respond to refugees fleeing terror.

Presidential candidates have weighed in, with many Republicans calling for keeping refugees from Syria, or other countries with an ISIS presence, out of the U.S.

There will be a few empty seats around one Thanksgiving table this year: Donald Trump and former Florida Gov. Jeb Bush are among those skipping Friday's Presidential Family Forum in Des Moines.
