Obama continues to champion the role of faith in public life, frequently summoning the spirits of the Rev. Martin Luther King Jr., Protestant theologian Reinhold Niebuhr and even St. Thomas Aquinas to frame his policies in moral terms. Like previous presidents, he regularly seeks the counsel of longtime Washington insiders, including Sojourners founder Jim Wallis, Reform Rabbi David Saperstein and retired Cardinal Theodore McCarrick, to shape decisions about the Iraq war, health care reform and the economy.
