Introduction General rule of theology: all punishments come from God, but not guilt; the punishments inflicted by God are for a higher purpose, namely our salvation (“pro nostra utilitate ad sanandum et curandum animas nostras”). God doesn’t enjoy giving punishments, just as the doctor doesn’t enjoy giving bitter medicine, but both act for our good. The case of the Passion of Christ is then dealt with (cf. infra), a punishment inflicted by God through the fault of Judas, the Jews and Pilate.

1) First part: concerning the Passion of Christ as medicina curativa. According to the doctrine of Augustine, neither before nor after the Passion of Christ was anyone ever healed of their sins, except as a result of the Passion of Christ itself (those who preceded that event were healed “ex fide passionis Christi fienda”). A figuration of the salvation of mankind through the Passion of Christ can be found in the episode of the serpens aeneus, “copper snake” (Numbers 21), which, according to Ferrer, is a figure of Christ (“sicut serpens eneus habebat formam serpentis et nullum habebat venenum, sic Christus est homo verus sed non habuit venenum peccati”) and would demonstrate that “Iudei ante passionem per mille et quingentos annos iam adorabant crucem”; this is followed by a review of the seven capital sins, each of which - except envy - is associated with a snake/demon (pride = serpens Leviathan; greed = serpens Mammona; lust = serpens Asmodeus; gluttony = serpens Beelphegor; wrath = serpens Baalberith; sloth = serpens Astaroth), from whose poisonous bite one can be saved by contemplating Christ on the cross. 2) Second part: concerning the Passion of Christ as medicina confortativa, i.e. a medicine that can also be given by doctors to healthy people to strengthen them: thus the passion of Christ can also be useful to the iustae, bonae et perfectae personae to strengthen them against temptations. A figuration of the Passion of Christ as medicina confortativa can be found in Exodus 15, 23-26 (episode of the bitter waters of Marah [= “tribulationes huius mundi, miserie, infirmitates, temptationes etc.”], made sweet by the lignum [= the lignum crucis, i.e. the remembrance of the passion of Christ] thrown in by Moses on God’s indication). The Passion of Christ is as much a cure for the seven capital sins (see above) as it’s a reinforcement for the seven virtues (Ferrer then reviews the seven virtues [3 theological + 4 cardinal virtues] and explains how each of them can be strengthened by the Passion of Christ). 3) Third part: concerning the Passion of Christ as medicina preservativa, i.e. a prophylactic medicine against the many infirmitates peccatorum resulting from the tempatationes dyaboli et occasiones mundi as much as from the inclinationes carnis. A figuration of the Passion of Christ as medicina preservativa can be found in the story of the prophet Jonah sent into the sea (reference to Jonah 1, 12): the sea, in fact, symbolises the mundus and Jonah is a figure of Christ who, sent into the world, preserves us from sin (“Jonas interpretatur columba, et significat Christum habentem simplicitatem columbinam qui mittitur in mare amarum”). So the human being, thinking how many and how great things Jesus suffered in this mare amarum, i.e. with his Passion, can abstain from sin.
