To provide students with opportunities for both spiritual and intellectual insight, BYU has hosted weekly devotional and forum assemblies since the school's early days.[115] Devotionals are most common and address religious topics, often with academic perspective or insight. Devotional speakers are typically drawn from the BYU faculty and administration or LDS Church leadership, including church presidents George Albert Smith, Spencer W. Kimball, Thomas S. Monson, and Russell M. Nelson.
