"J. Gresham Machen played a key role in the theological debates of the 1920s and 1930s. His work has been studied and evaluated from many angles. What is less well-known and less well considered is his service in the First World War. Although he objected to American involvement, he participated as a volunteer in the YMCA. From these rare letters the reader can see a fresh side of the great scholar. On the battle fields of France he was simply known as a compassionate soul who brought solace to scores of suffering soldiers. For those who only know Machen the polemicist, this volume will showcase Machen the caregiver" -- William Edgar, Professor of Apologetics, Westminster Theological Seminary.
