Tractatus de imposturis et ceremoniis Iudaeorum nostri temporis

Moreover, if anyone has shed the blood of this man with a bloody point, they declare that he has done a most pleasing work for the Lord, they pray well for him, and they commit this illustrious deed to the memory of posterity in their records with these words: Secher Zatick librotho: "May the mention of this man be eternal in the heavenly houses." They harass the slain with these words: Schem reschoim Irkaf: that is, "May the name of this scoundrel be consumed and abolished by eternal fire." They so rejoice and delight in the evils and inconveniences of those who acknowledge their salvation and redemption received from Christ that they exult and wish them to be conflicted with every kind of calamity with these words: Keri lof tu kol oi we lehoua: "So may the enemies of God be evilly destroyed." Lemach schemo besëchro: "May their name and memory be obliterated, and may they be guilty of all our sins and bear the punishment; may the parents who begat, educated, and fed them perish." Finally, by the grave and severe law of the Rabbis, it is commanded that they flee, shudder at, and avoid the custom and familiarity of those who have defected, etc. From these words of a most learned man, the detestable blasphemies and execrations of the Jews become conspicuous. But in the first place, this is to be noted: that he says they continue sins with sins, and blasphemies with blasphemies. For he who declares war against Christ the Son has declared it against the Father and the Holy Spirit. For everyone who honors and observes the Son also observes the Father; for the Father, as it is in John 13, is honored in the Son. Therefore, to propose briefly what I intend: whoever knows that the ignominy with which the Son is affected redounds to the Father, he will easily estimate the gravity and atrocity of the crime with which they bind themselves. Not without reason does our negligence and slothfulness bring much trouble to the minds of the pious, for when we ought to defend and fight for the glory of Christ with all the effort of our minds, we desert our duty and allow these slanderers to profane His name with horrible insults and dire execrations with impunity. May we finally be ashamed that the children of this world defend their impious errors, by which they are led to destruction and ruin, more vehemently than we defend the eternal and inviolable truth of God, of which no good man has doubted.
