Amid all the uncertainty in the world today, there are those who rely upon religious beliefs and those who find comfort believing in no God at all. We spent the year looking at stories across the spectrum, from the journey of Pope Francis and those who are inspired by him to a scandalous secret that led to salvation and a family that traded traditional faith for the Flying Spaghetti Monster.

When you live in the Bible Belt and come from a big Irish Catholic family, you’re not supposed to become a nonbeliever, much less lead a new phase of atheism.

What he discovered belied the stereotypes often attached to atheists.

Their family and friends called them crazy. Maybe they were. The husband and wife from Buenos Aires, after all, had packed up their four children in a VW bus and set out on a 13,000-mile journey through 13 countries. Their destination: Philadelphia, Pennsylvania, to see Pope Francis. CNN’s Moni Basu hopped on board for part of the ride. And later, much later, the pontiff did indeed meet the family.

Could this Quran curb extremism?

Many English translations of the Quran have been ill-suited to foiling extremist ideology or introducing Americans to Islam. Ten years in the making, “The Study Quran” is an effort to change that.

In a landmark opinion, a divided Supreme Court ruled that states cannot ban same-sex marriage, establishing a new civil right and handing gay and lesbian advocates a long-sought victory. But as several justices noted in forceful dissents, the war between religious and LGBT rights is far from over. CNN’s Religion Editor Daniel Burke explores the landscape of this battlefield.
