Loretta M. Long examines the life and influence of Selina Campbell, one of the most visible women in the 19th-century Disciples of Christ movement. Best known as the wife of Alexander Campbell, founder of the Disciples, Selina Campbell both shaped and exemplified the role of women in this dynamic religious group (also known as the Stone-Campbell movement). Her story demonstrates the importance of faith in the lives of many women during this era and adds a new dimension to the concept of the ""separate spheres"" of men and women, which women like Campbell interpreted in the context of their religious beliefs.

A household manager, mother, writer, and friend, Campbell held sway primarily in the domestic sphere, but she was not held captive by it. Her relationship with her husband was founded on a deep sense of partnership conditioned by their strong faith in an all-powerful God. Each of them took on complementary roles according to the perceived natural abilities of their genders: Alexander depended on Selina to manage his property and raise the children while he travelled the country preaching. Campbell outlived her husband by 30 years, and during that time published several newspaper articles and supported new causes, such as women in missions.

In the end, as Long amply demonstrates, Selina Campbell was neither her husband's shadow nor solely a domestic worker. She was, in her husband's eyes, a full partner and a ""fellow soldier"" in the cause of Restoration.
