Barack Obama has repeatedly stated that he is a committed Christian, and there is no credible evidence to the contrary. He was sworn into the Senate on his family Bible, and sworn into the presidency on a Bible used by Abraham Lincoln. He has regularly attended church with his wife and daughters for years. Questions have arisen due to the fact that his biological father had a "Muslim name" and was born into Islam. However, his father had long since left the religion and become an atheist by the time the future president was born. Further, Barack Obama's mother was a non-practicing Christian, so she raised her son to be spiritual and respect all religions. It was when he went to live with his maternal grandparents, who helped to raise him, that he lived in a home where a religion was observed-- Protestant Christianity.,, .
