Occasion. The eighth of the twenty-five Public Disputations printed in the Opera and in Nichols's English, defended under Arminius by the respondent whom Nichols prints as Caspar Wiltens. It follows the disputation on the first sin of the first man and takes up the sin that each person commits.
The doctrinal move. Actual sin is first defined as what a man commits, through the corruption of his nature, once he can use reason: something thought, spoken or done against the law of God, or the omission of what it commands, in a word the Apostle's anomy (I). The theses then run through a series of divisions. Sin is of commission or omission, and is committed against the Law or against the Gospel (II); it is per se or per accidens (III); it is against God, our neighbour or ourselves (IV); from its cause it is a sin of ignorance, infirmity, malignity or negligence (V); it is against conscience or not (VI); and from its real object it springs from the lust of the flesh, the lust of the eyes or the pride of life (VII). Venial and mortal are taken to mark not the nature of sin but God's gracious estimation of it, every sin being of its own nature mortal (VIII), and the Stoic equality of all sins is refused (IX). Sin unto death and the sin not unto death, the pardonable and the unpardonable, are set side by side (X). The sin against the Holy Ghost is defined and the reason for its being called irremissible is given, in the justice and equity that bound God's mercy (XI, XII). The disputation closes with the four causes of actual sins (XIII) and their effects (XIV).
