The Theology of Holiness
by Dougan Clark
About the author
Born in 1828, he was associated with the Quaker world of the American Midwest and became known as a minister, doctor, and author. Reliable library and reference records connect him with Haverford College, medical study, and teaching at Earlham College in Indiana.
His writing focused on Christian holiness and spiritual life, with works including The Theology of Holiness and The Offices of the Holy Spirit. Readers often find his style direct and earnest, aimed less at abstract argument than at helping ordinary believers think about faith in daily life.
He died in 1896, but his books have continued to circulate through reprints and digital archives. Today he is remembered mainly for devotional and theological works that grew out of the Friends tradition and its strong emphasis on inward spiritual experience.
