Decline and Dysfunction in the American Church proposes an interdisciplinary explanation, one that converges at the intersection of Christianity and psychology. Based on his research of over 25 years of parish and diocesan ministry, Culpepper contends that the American church has, for many, become irrelevant to their lives due to the toxic influences of co-dependent patterns of behavior. The same co-dependent behaviors that devastate the efforts of human families to love and support one another effect church congregational and denominational “families” in similar ways.
