This collection brings together essays and papers produced by the veteran scholar, Duncan Shaw, from 1967 to 2010, including those previously difficult to access, such as ‘Action, remembrance and covenant: Zwinglian contribution to the Scottish Reformation understanding of the Lord's Supper’. They reflect Shaw's abiding concern with the interaction between Zwinglian thought and the Scottish Reformation and the key people and developments that helped to create the Protestant Church in Scotland. The most recent, and hitherto unpublished, paper on the Scottish 1560 ‘Reformation Parliament’ contains a useful biographical appendix of attendees. By taking the genealogical aspect so seriously, Shaw has revealed the intricate web of family relationships that bound, and divided, the Scottish political nation. Unfortunately, the essay does not mention the online Records of the Parliaments of Scotland to 1797 [http://www.rps.ac.uk/] that has become the standard edition. Although it is sensible not to update essays published in past decades this can leave younger scholars stumbling across old battlefields trying to make sense of half-buried trenches. Over the years Shaw rightly expended great effort in explaining, particularly to a Scottish audience, that Protestant and Calvinist were not synonymous. His championship of Zwinglian thought was very important, though it has been overtaken by the recent emphasis upon the highly varied and complex nature of the entire ‘Reformed’ tradition. The cumulative effect of Shaw's essays does add to this emphasis, but readers are left to recognise those additional flavours themselves.
