Mr Obama talked about his beliefs when he was asked, "Why are you a Christian." The question was posed by a woman at a backyard conversation, part of a series of meetings Mr Obama is holding to talk informally with Americans.
Some conservatives and political opponents have questioned Mr Obama's Christian faith and a Pew Research Center poll in August found that 18 per cent of Americans wrongly believe that the president is Muslim - up from 11 per cent who said so in March 2009. Just 34 per cent said they thought Obama is Christian.
"I'm a Christian by choice," Mr Obama said. "My family didn't - frankly, they weren't folks who went to church every week. And my mother was one of the most spiritual people I knew, but she didn't raise me in the church.
"So I came to my Christian faith later in life, and it was because the precepts of Jesus Christ spoke to me in terms of the kind of life that I would want to lead - being my brothers' and sisters' keeper, treating others as they would treat me," he continued. >>> | Wednesday, September 29, 2010
