Robert Barclay, the most prominent theologian in the early Quaker church, was born in Gordonstoun, Scotland. In his early days, Barclay fought under Gustavus Adolphus and served as a Scottish member of the British Parliament. Following his father into the Quaker organization in 1667, he became their main defender. His Apology for the True Christian Religion (1676) is considered a classic exposition of Quaker principles.
Handley Carr Glyn Moule was born at Fordington, England. Ordained in 1867, he pastored at his father's church in Dorset from 1867-80. He succeeded B. F. Westcott as Bishop of Durham. This theologian believed in the authority of the Scripture, and was associated with the Keswick Movement in his latter years. A profound scholar, he could nonetheless speak and write for ordinary people. Bishop Moule published commentaries on nearly all the Pauline Epistles.
