Without peer among Irish Friends as an organizer, Sharp played a key role in assisting fellow Quakers to survive repression and to evolve from a small sect into a denomination. With his second wife, Ann, he helped shape the rigorous style of dress and home furnishings that set the Irish Friends apart from their coreligionists in England. Tireless in his work as a secretary, treasurer, and fund-raiser, he served on the committee that monitored the proceedings of the Irish Parliament and helped pioneer the Friends' home and shop visitations. Sharp took up his pen to defend Quakers in "the Lamb's war" against critics on all sides—Catholics, Anglicans, nonconformists, and sectarian extremists. When James II extended toleration to nonconformists, Sharp seized the opportunity to become a Dublin alderman and sit on committees whose purview ranged from cleaning the city streets to overseeing the workhouse for the indigent. He attained prominence in the weavers' guild, serving as master in 1688-89 and sitting on its council for years. Notwithstanding his distinctive dress, his refusal to take oaths or pay tithes, and his plain speech, he enjoyed the respect of the rich and powerful. is not only a biography of Sharp but a portrait of Dublin's community of Friends. The author explains in detail the functioning of national, provincial, and local meetings; the Friends' work in educating and disciplining their members; their provision of charity to the needy; and their efforts to ransom captives in Muslim lands. In undertaking these activities, Sharp and his fellow Quakers expressed the driving force of their faith and built a society that sustained the Friends for centuries to come as a minority within another minority, the Protestants of Ireland.
