Joseph Tuckerman and the Outdoor Church is about the Rev. Joseph Tuckerman, a Unitarian minister who created and led a street ministry in Boston, Massachusetts, between 1826 and 1839 at the behest of his friend and college roommate, William Ellery Channing. Because of Tuckerman's innovative approach to encountering and helping the poor people he met near the Boston wharves, he is considered the father of American social work as well as a prescient, dedicated, and socially active minister whose work led directly to the Social Gospel Movement. The book examines and interprets Tuckerman's theology and ministry of outreach in light of the author's experience as pastor of the Outdoor Church of Cambridge, Inc., an outdoor ministry to homeless men and women in Cambridge, Massachusetts. The Outdoor Church offers prayer services and pastoral assistance outdoors in all seasons and all weather in order to be accessible to chronically homeless men and women who, because of shame or embarrassment, hostility or illness, cannot or will not enter conventional churches. Joseph Tuckerman and the Outdoor Church is a unique and gripping look at a radically innovative nineteenth-century minister through the prism of the actual application of his thinking and his example to an ongoing ministry to the chronically homeless men and women of Cambridge.
