Occasion. The forty-first disputation of the fourth Leiden cycle, defended 25 October 1606 under Arminius by Nathan Vaius of Flushing. In the Syntagma it follows Disputation XL, which ends on monastic vows. It is followed by Trelcatius's Disputation XLII, De Baptismo (4 November 1606), which opens by naming this disputation as the general treatment that the special ones now follow. It has no preface. Stanglin LV (Chalmot, 1605) covers the same locus in an earlier disputation, and it is a different text.
Authorship. By the convention of the Leiden faculty the theses are the presiding professor's; the student defended them. Stanglin argues the case for Arminius's authorship of the disputations at length, and it is his argument, not ours.
The doctrinal move. Arminius starts from the word, the soldier's sacramentum or oath (I), narrows it twice (II–III), and gives the definition (IV). Then he unfolds its terms (V–VI) and runs the thing through its causes: the author (VII), the matter (VIII), the external and internal form (IX–X). From the form he derives the figurative speech of Scripture about sacraments (XI) and the differences between sign and thing signified (XII). He then fixes the subjects (XIII), the end (XIV) and the lawful use (XV). The last theses mark the sacrament off from its neighbours, the word (XVI) and sacrifice (XVII). They close on the number of the sacraments under both covenants and how the old and new sacraments compare (XVIII–XIX).
Where it is answered. No answer by Gomarus or in Wesley's writings is identified for this disputation. It names no opponent. The opinions it rejects in IX, X, XIII and XIV are left unattributed.
