The Blue Banner is a case study of the survival of historic denominationalism grounded in resistance to church union. It traces the origins and near demise of Presbyterianism in Nova Scotia and the development of Saint David's from its beginnings as a new congregation and the only site of Presbyterian witness in metropolitan Halifax. The authors look at various aspects of congregational life - corporate structure and governance, education, worship and music, volunteerism, mission and outreach, and stewardship of the historic site and building that has been home to Saint David's since the beginning.
