Cosmo Gordon Lang [SEP] Introduction
Beginning in 1890, his early ministry was served in slum parishes in Leeds and Portsmouth, except for brief service as Vicar of the University Church of St Mary the Virgin in Oxford. In 1901 he was appointed suffragan Bishop of Stepney in London, where he continued his work among the poor. He also served as a canon of St Paul's Cathedral, London. In 1908 Lang was nominated as Archbishop of York, despite his relatively junior status as a suffragan rather than a diocesan bishop. His religious stance was broadly Anglo-Catholic, tempered by the liberal Anglo-Catholicism advocated in the "Lux Mundi" essays.
