Occasion. The twenty-sixth disputation of the fourth Leiden cycle, defended under Arminius by Philippus Adriani Pynacker; the reprint dates it 21 February 1606, Stanglin's quarto 22 February. It has no preface linking it to the disputations around it. It is the corpus's one disputation given wholly to controversy with Rome, and it names its opponent on nearly every page: Bellarmine, whose treatises on indulgences, penance and purgatory supply the margins.
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 takes the Roman definition of an indulgence (I) and reduces it to three foundations: a treasury of satisfactions, the faithful's need of it, and a power to dispense it. He then removes each in turn: the treasury (II–IV), the need, through the three things Rome must prove about temporal punishment (V–VIII), the power of the keys (IX). Purgatory is handled the same way. He first separates three senses of "purgatory" and keeps two (X), then lines up eight numbered reasons against the third (XI–XIII). He closes with an argument drawn from Rome's own premises (XIV) and a question put to the Pope's charity (XV).
Where it is answered. No answer by Gomarus or in Wesley's writings is identified for this disputation. The locus was not in contest among the Reformed. Wesley's 1784 Articles of Religion keep the Anglican rejection of "the Romish doctrine concerning purgatory, pardon" (Art. XIV), but that is common Protestant ground, not a reply to this text.
