The U.S. Senate, starting this day, April 25, 1789, decided to open every session with prayer, continuing the practice of the Continental Congress during the Revolution. The first chaplain was Bishop Samuel Provoost, who conducted George Washington's Inaugural Service at St. Paul's Chapel. All 61 Senate chaplains have been Christian, though leaders of other faiths periodically have been invited to offer prayer. The U.S. Senate chaplain after World War II was Peter Marshall, who prayed: "Our liberty is under God and can be found nowhere else. May our faith be ... not merely stamped upon our coins, but expressed in our lives."
