Texas Gov. Rick Perry's campaign has targeted what it calls President's Obama's "war on religion."
The Republican presidential candidate has started a massive $1.2 million broadcast advertising schedule promoting the country's Christian heritage.
Perry is targeting social conservatives in Iowa as he tries to breathe life back into his campaign. It is estimated that he will spend more than $650,000 on broadcast time showcasing his Christian faith this week alone.
"We're sitting in a good place at this particular point in time," Perry told CNN. "Obviously, we're going to be in South Carolina a good bit over the course of the next two weeks. But Iowa is the real focus."
The television commercial begins airing just as the president has begun a push to expand gay rights around the globe.
"I'm not ashamed to admit that I am a Christian. But you don't need to be in the pew every Sunday to know that there is something wrong in this country when gays can serve openly in the military, but our kids can't openly celebrate Christmas or pray in school," Perry said.
Politcal analysts also say the the commercial is a sharp contrast with rival Mitt Romney's Mormon faith and with Newt Gingrich.
Gingrich is a recent convert to Catholicism. He has been divorced twice.
"The evangelical Christians are waiting to, you know, find that individual that they're really comfortable with, that they think can win, that has their values," Perry told CNN, adding: "I fit their mold quite well."
"My faith is part of me," Perry continued. "The values that I learned in my Christian upbringing will affect my governing."
