Children's Special Service Mission

Children's Special Service Mission was the original name, from 1867, of the organisation now called Scripture Union. Begun by Thomas 'Pious' Hughes and Josiah Spiers in Islington, London, this evangelical Christian movement was less formal than the Sunday Schools of the day and attracted children who in turn brought their friends. Several notable people have participated in this mission of the likes of Stanley Andrew Morrison.

CSSM grew into an international movement that included missions in buildings, and beach missions.
