Flag of the United States
The Rev. Dr. George MacPherson Docherty preached a Lincoln Day sermon on February 7, 1954, to a congregation that included President Eisenhower. The sermon, titled "A New Birth of Freedom," is credited with prompting the U.S. Congress to amend the Pledge of Allegiance to the Flag of the United States, inserting the phrase Lincoln used at Gettysburg, "under God."
