This is a detailed study that examines Bullinger's thinking on prophecy from a wide angle before becoming more and more focused. It commences with the Christian tradition on prophecy generally (ch. ii) and then takes up prophecy in sixteenth-century Zurich (ch. iii), looking at Ulrich Zwingli, Balthasar Hubmaier and the Schleitheim articles. Timmerman then devotes three chapters to individual writings by Bullinger: De propheta libri duo (ch. iv), De prophetae officio (ch. v) and De episcoporum institutione et functione (ch. vi). Each of these chapters is a comprehensive analysis of Bullinger's thinking at a given point in time, 1525, 1532 and 1538 respectively. The monograph is careful to show both Bullinger's reliance on the Zurich heritage and on Zwingli in particular, but also the ways in which Bullinger distanced himself from Zwingli with the passing of time. Chapter vii looks at Bullinger's involvement with the Zurich ‘Prophezei’. The study addresses numerous extremely relevant questions related to how Bullinger refined his thinking on prophecy and the sacred languages, rhetorical training, exegesis, the covenant, relationship to other ministerial offices, to the magistrate and to church discipline. This is a well-written book which contains sober, penetrating reflection, and interacts carefully with scholarship on the subject.
