Other presidents who number among the most devout are the Methodist William McKinley, the Presbyterian Woodrow Wilson, and Unitarian John Quincy Adams. All of these men were fervent believers who attended church, prayed, and read the Bible regularly. Adams worshiped at three different churches (Unitarian, Presbyterian, and Episcopal) and would attend service even in heavy snow. He was also vice president of the American Bible Society and wrote religious poetry. During an 1846 debate over the Oregon territory (when he returned to Congress after his presidency), he cited the Book of Genesis. Abraham Lincoln is sometimes named among our most religious presidents, and indeed he had deep struggles with questions of religion. However, he did not widely profess his private believes and is known to have doubted the divinity of Jesus. Ronald Reagan, Bill Clinton, George W. Bush, and Barack Obama have been among the presidents to use the most religious rhetoric in their speeches, though this is partly due to the precedent set by Carter.
