Introduction Interpretation of the thema: the Samaritan woman is the reasonable soul who, being in sin, asks to haurire aquam, that is, to receive grace.
Divisio (see above) 1) First part: three definitions of “sin”: 1. “sin is deprivation of human goodness” (reference to Bonaventure, Commentaria in quattuor libros sententiarum Magistri Petri Lombardi, II); cf. Peccatum est carentia boni ubi debet esse (quote from Augustine’s De civitate Dei); according to Bonaventure, God has given human beings three supremely necessary goods: 1) “mesure” (i.e. desire nothing against the divine will; «sin has perverted this order, because now the human heart always desires and thinks evil, i.e. carnality and sensuality»); 2) “beauty” (the true beauty and nobility of the human being is the virtue; reference to Seneca [probably to Epistulae ad Lucilium, LXXVI]); 3) order (i.e. directing thoughts, actions and words to God; sin diverts our operations from God). So, “sin is deprivation of beauty, order and measure” (reference to Augustine). 2. “Sin is separation from what is according to nature and conversion to what is against nature” (reference to John of Damascus); as the sick person, whose nature is vitiated by illness, desires harmful things more than healthy things, so the sinner despises virtue and loves vices. 3. “Peccatum est, bono incommutabili [i.e. God] spreto, adherere bono commutabili [i.e. the human being]” (quote from Augustine's De libero arbitrio). 2) Second part: two operations of sin: 1. “Peccatum est prevaricatio divine legis et celestium inobedentia mandatorum” (quote from Ambrose (Saint), De Paradiso); three main laws: 1) “natural law”; 2) “law of Scripture” (i.e. the law given by God to Moses); 3) “law of grace” (i.e. the gospel of Christ, perfection of all laws). Sin is prevarication of all these laws (several biblical exempla for each law). 2. “expolation of virtue”, because sin is against human nature (“Everything that does not please God is against nature” [reference to Bernard of Clairvaux]), while virtue is according to it.
Conclusion Invitation to avoid sin, even at the cost of losing one's home, relatives and everything else (direct appeal to the preacher to rebuke «friars, priests, monks, merchants, gentlemen, widows and maidens who offend God for a penny»).
