his assistant at St. Paul's College and Grammar School, John Barrett Kerfoot, who later became the first bishop of Pittsburgh and founded Trinity Hall School for Boys (1879) using Muhlenberg's principles. For his work in education, Kerfoot received an honorary doctorate from Cambridge University. Henry Augustus Coit (1830–1895), a former student of Muhlenberg and Kerfoot, was the founding rector of St. Paul's School in Concord, New Hampshire (1856). Kerfoot's nephew was the founding headmaster of St. Mark's School in Southborough, Massachusetts (1865). Endicott Peabody (1857–1944) founded Groton School in 1884; acknowledging Muhlenberg's influence, he kept his portrait in his study and referred to Groton as a "church school". The founders of St. George's School in Rhode Island (1896) also cited Muhlenberg as an educational pioneer, and he influenced the 1839 founding of the Episcopal High School in Alexandria, Virginia. Muhlenberg consulted with EHS founding headmaster William Nelson Pendleton, and sent acolyte Milo Mahan (who taught at St. Paul's in College Point) at the request of the Bishop of Virginia. Historian James McLachlan noted the Muhlenberg schools' uniqueness in American Boarding Schools: A History (1970). Religious beliefs Muhlenberg's religion can be difficult to describe. His mature religion may be described as Anglican Christianity with an American accent. He was claimed by different parties within his denomination—the High Church, the Evangelical, the Low Church—but proceeded in his own way. In some respects, he was an early example of what came to be called the Broad Church. He opposed the "novelties" of Roman Catholicism and dogmatic Protestantism, affirming the Scriptures and church teaching before the 11th-century East–West Schism. Muhlenberg echoed the 17th-century Anglican bishop John Cosin who wrote that his Anglican church was "Protestant and Reformed ... according to the Ancient Catholic Church." His position was also similar to Edward Bouverie Pusey (1800–1882), an Oxford professor and a leader of the 19th-century revival movement in the Church of England. Muhlenberg was influenced by the Oxford Movement, William White (1748–1836), John Keble, John Henry Newman, Pusey, Richard Hooker (1554–1600) and the Christian tolerance of Jeremy Taylor (1613–1667). As a youth, Muhlenberg worked to become quite familiar with the Fifteen Sermons and Analogy of Religion of Bishop Joseph Butler (1692–1752). Born a Lutheran, Muhlenberg converted to the Protestant Episcopal Church as a boy. Trained in Philadelphia by William White and prepared for ordination by Jackson Kemper, he began to call his religion "Evangelical and Catholic"
