A federal court has ruled that Oklahoma cannot implement a state ban on Islamic Sharia law. The 10th Circuit Court of Appeals upheld a previous ruling blocking Oklahoma's Sharia ban.

Americans' religious liberties are under attack — or at least that's what some conservatives say.

Newt Gingrich warns the U.S. is becoming a secular country, which would be a "nightmare." Rick Santorum says there's a clash between "man's laws and God's laws." And in a campaign ad, Rick Perry decried what he called "Obama's war on religion," saying there is "something wrong in this country when gays can serve openly in the military but our kids can't openly ... pray in school."

Any discussion of Newt Gingrich's journey to Catholicism begins with his wife.

"I have always been a very spiritual person," Callista Gingrich told the Christian Broadcasting Network this year. "I start each day with a prayer, and pray throughout the day, because I am grateful for the many blessings that God has bestowed upon us."

In 2011, hell was a hot topic, from Hollywood to New York Times bestsellers. In fact, this year has seen an incendiary debate about the existence and contents of hell.

The year began with an epic battle between a priest and Satan, with Anthony Hopkins playing a demon possessed priest in the movie, The Rite. The Hollywood glimpse of the underworld came and went without much notice by moviegoers. But then, another form of hell on earth grabbed the headlines. Judgment Day would soon be upon us.

In February 2006, 5-year-old Jake Finkbonner fell and hit his head while playing basketball at his school in Ferndale, Wash. Soon, he developed a fever and his head swelled. His mother, Elsa, rushed him to Seattle Children's Hospital, where the doctors realized Jake was battling a flesh-eating bacterium called Strep A.

"It traveled all around his face, his scalp, his neck, his chest," she recalls, "and why it didn't travel to his brain or his eyeballs or his heart? He was protected."

Writer Christopher Hitchens, who died on Thursday from complications of cancer at the age of 62, leaves behind some 18 books and countless essays on politics and public figures, but his most lasting legacy may be his atheism and his long-running duel with what he considered the world's most dangerous threat: religion.

One of the puzzles of the Republican presidential campaign is Newt Gingrich's appeal to religious conservatives. The irony is that Gingrich, a Catholic convert who has had three marriages, is outperforming Romney, a lifelong Mormon and family man. In fact, less than a month before the Iowa caucuses, the former speaker of the House has three times the support of evangelicals in that state that Mitt Romney, the former governor of Massachusetts, does.

This weekend, Catholics may experience a little surprise when they attend Mass. The words and music are different, thanks to the first major change of the English-language Mass in more than 40 years.

For many practicing Catholics, this will be a major adjustment.

So on a recent Sunday, the Rev. Chester Snyder of St. Joseph's church in Mechanicsburg, Pa., did a trial run through the new liturgy with his parishioners.

The man said the advances began when he was 10 years old. He was a fourth-grader and an altar boy at a Catholic school in Hudson, Mass. He said the priest would try to touch the altar boys when they were putting on their robes, and he'd invite them to the rectory, one at a time.

"He'd want to show us pornographic magazines, and ask us to take our pants down, and he'd take his pants down and expose himself and things like that," he said.

A few years ago, Father Tomasz Trafny was brainstorming with other Vatican officials about what technologies would shape society, and how the Vatican could have an impact. And it hit them: Adult stem cells, which hold the promise of curing the most difficult diseases, are the technology to watch.

"They have not only strong potentiality," says Trafny, "but also they can change our vision of human being[s], and we want to be part of the discussion."
