Lighthouse Trails in the article Obama: Grew up with “the Bible and the Koran” – Believes Many Paths Lead to God has the following quote from The Faith of Barack Obama written by Stephen Mansfield.

Obama does clearly believe that the form of Christianity that he committed to at Trinity Church in 1985 is not the only path to God. “I am rooted in the Christian tradition,” he has said. Nevertheless he asserts, “I believe there are many paths to the same place and that is a belief there is a higher power, a belief that we are connected as a people.” He first saw his broad embrace of faith modeled by his mother. “In our household,” he has explained, “The Bible, [t]he Koran, and the Bhagavad Gita sat on the shelf . . . on Easter or Christmas Day my mother might drag me to a church, just as she dragged me to the Buddhist temple, the Chinese New Year celebration, the Shinto shrine, and ancient Hawaiian burial sites.” (p.55 of Mansfield’s book, quoting from Audacity of Hope, Obama, p. 203).
