When did Barack Obama change his faith?

Answer 1

Never. He was born to a mother who was a non-practicing Christian, and to a father who had been born into Islam but left that religion and became an atheist. The young Barack was raised to respect all faiths, but his family did not practice any. In fact, even when he lived in Indonesia for four years with his new step-dad (a moderate Muslim), he was never expected to practice Islam and there is no credible evidence he attended Muslim religious schools, contrary to internet myths.

As a youth, he was raised by his grandparents, who were Protestant Christians, but he did not become interested in practicing Christianity till the late 1980s, when he began to date Michelle Robinson, who would later become his wife. Thus, although the president was never religious till then, he never changed from one thing to another. He simply went from being indifferent but respectful towards religion to becoming more involved in the Christian religion that his grandparents and wife practiced.
