William Pierson Merrill (1867–1954) was an American Presbyterian clergyman, pacifist, author, and hymn writer. He was acknowledged during his time as one of the most influential ministers in America.[1] He is probably best remembered as the author of several well-known hymns, including "Rise Up, O Men of God".
Upon his ordination in 1890, Merrill became pastor of Trinity Presbyterian Church in Chestnut Hill, Pennsylvania, where he served until 1895.[3] From 1895 until 1911, he served as pastor of the Sixth Presbyterian Church of Chicago. There he met his wife Clara (née Helmer).[2] In 1911, Merrill was called to the Brick Presbyterian Church in New York City, where he served as pastor until 1938,[4] when the merger with the Park Avenue Church took place and he resigned to become pastor emeritus.[5]
Merrill was named the first president on the Church Peace Union, an organization of religious, academic, and political leaders aimed at promoting pacifism.[6] His 1914 sermon titled "The Making of Peace" was hailed by Andrew Carnegie as "...one of the greatest sermons on peace that he had ever heard."[7] Merrill was offered the presidency of Union Theological Seminary in 1917, but declined.[8] He was elected Moderator of the Presbytery of New York in 1940,[9] a position he held until 1942.[10]
