Albert Benjamin Simpson was born on Prince Edward Island and was pastor of a prosperous Presbyterian church in New York when he resigned it — because the congregation would not receive the Italian immigrants he had been evangelising. He began again in a hall, preaching to whoever came.
Out of that work grew the Christian and Missionary Alliance, a missionary movement rather than a denomination at first, and a training school that became Nyack College. Simpson's 'fourfold gospel' — Christ as Saviour, Sanctifier, Healer and Coming King — became one of the formative shapes of the Holiness and early Pentecostal movements, though Simpson himself kept a careful distance from some of what followed. He wrote a great deal, including hymns he composed for his own congregations.
