Created to support Episcopalians in military service, this church commission is best known today for compiling practical prayer books and devotional resources for soldiers and sailors during World War II.

by Episcopal Church. Army and Navy Commission
This author credit refers to a church body rather than a single person. Contemporary catalog and ebook records identify the Episcopal Church. Army and Navy Commission as the corporate author of A Prayer Book for Soldiers and Sailors, a devotional work published in the early 1940s for members of the armed forces.
The commission appears to have been part of the Episcopal Church’s ministry to military personnel, preparing worship material meant to be portable, comforting, and useful in wartime life. That makes this “author” less a literary personality and more an institutional voice: a committee shaped by pastoral care, liturgy, and the needs of service members.
Because this is an organizational author, not an individual, a standard personal portrait is not readily available. Readers encountering this name are really seeing a snapshot of how the Episcopal Church tried to bring prayer, order, and reassurance to soldiers and sailors during a time of global conflict.
