This book contains the proceedings of the sixth RefoRC Conference, held in Copenhagen in 2016. Twenty-six scholars from ten European countries and the US contribute papers on four main themes—the way the Church was understood in the sixteenth century, the Church and art, ecclesiology, and Church unity. The themes range from general studies on subjects like the late medieval view of the Church to specialized investigations of the Reformation's impact on a village in Transylvania and the representation of the Good Samaritan in Reformation art.

As one would expect, Luther and Calvin are well represented, but there are also papers on Zwingli, the Bohemian Brethren, Erasmus, and even Robert Bellarmine. Each contribution is accompanied by an extensive bibliography, which will enable the interested reader to pursue the chosen topic further. There is also a comprehensive index of names which makes it easy to locate particular individuals across the collection as a whole.

The range of scholarship is impressive and the reader is introduced to research being done by Reformed historians in Hungary, Romania, and the Czech Republic, as well as in Germany, Switzerland, and the Netherlands. The English-speaking world, with only three essays, is under-represented, although twenty-two of the papers are in English, with the remaining three in German (with no English summary).

English-speaking scholars will find this exposure to European research stimulating and refreshing. It will broaden the horizons of those who concentrate on the British Isles, reminding them of the pan-European dimension of the Reformation and its origins in what was then the Holy Roman Empire. Unfortunately, the quality of the English tends to suffer from the fact that most of the contributors are writing in a foreign language, and the editors would have done well to employ a native English-speaker as a copy editor, who could have smoothed out the style here and there and made the texts easier to read. The effort is certainly worthwhile and this volume will be an important addition to library collections everywhere.
