Keith Stanglin is very productive in publications and projects related to the Dutch theologian Jacobus Arminius. In this work he edits and introduces the sixty-one public disputations that Arminius composed during his time as professor of theology at Leiden University. It is particularly valuable that this edition includes thirty-six of the disputations that have never before been published, and have been not been considered in research on Arminius, his theology and his influence. Stanglin's critical edition presents these texts in the original Latin, complete with notes and summaries in English. The disputations deal with all the major loci theologici and, assuming that Arminius was the author of all of them, they can be seen as his systematic theology. This is therefore interesting since Arminius studies, by both friends and foes, have for a long time been rather one-sided and definitely incomplete, and it is certainly time that he be studied from his own works. The texts are preceded by an introduction to the genre of theological disputation, which contributes to an interesting discussion as to the authorship and value of early modern academic disputations in general. Stanglin rather convincingly tries to demonstrate Arminius's primary authorship of these documents.
