William Cunningham was too careful a student of the Reformation period merely to follow traditional Protestant interpretations. Here for example, he rejects the common readiness to blame Zwingli for the manner of his death on the battlefield of Cappel. On the other hand, he is not slow to offer critical comment of the Reformers or their teaching where he believes that is warranted. Thankfully, shortly before his death, Cunningham committed to James Buchanan and James Bannerman, his colleagues at New College, the manuscripts he had already prepared for the press. These included the essays published in this volume, some of which continue to be recognized as landmark studies in the theology of the Reformation.
