This monograph, written from a viewpoint at the very centre of the Church of Scotland's legal system, exposes deep flaws in the constitutional settlement of Church and state in Scotland - a settlement often envied by other Churches. Marjory MacLean combines legal and theological techniques to sketch a better approach to the legal authority of national churches - 'the sovereignty of servanthood' - and calls for a more trusting engagement between civil law and church law. Students and scholars of both constitutional law and church governance will respoond to this argument, and to the survey of Scotland's national Church.
