[De communione et conversatione Iudaeorum et Christianorum]

our God, 13th chapter. If your brother and your friend, and the wife who sleeps in your bosom, wishes to deprave or damn the truth, let your hand be upon them, and you shall pour out the blood of their malice. For Jerome says to Riparius, and the canon 23rd question 8th chapter "Legi" assumes it: it is not cruelty to punish crimes for God, but piety. And he exemplifies it from Phineas, Numbers 25; from Elijah, 4 Kings 1; from Peter, Acts of the Apostles 5; from Paul, Acts 13. Thus, the gloss says that the same is for all who are not Catholics, and it does not distinguish between death and life: here, since they can and ought to take nothing from us. Regarding that, there is broadly the canon 24th question 2nd chapter "Sane," by the contrary sense, where it declares broadly by authorities that we are not to abstain from their alms through death, with whom we communicated in life. Wilhelmus says this is to be understood, as the gloss also invites, unless he has bequeathed to help them in extreme necessity. Here, successions of the personal property of Christians are regularly prohibited to Jews.

Twelfth. Jews are not to be admitted to legitimate acts, because the canon 2nd question 7th chapter "Alieni erroris" says: we decree that all are infamous who deviate from their own faith or the Christian law, or who freely postpone the authority of their own or regular law. Thus, no Jew may presume to provide testimony against a Christian, but contrarily, the testimony of Christians against them ought to be admitted. It is clear from the Lateran Council which is placed in Extra de Testibus, chapter "Iudaei," where the text says: We decree that the testimony of Christians against Jews in all causes should be admitted, since they presume to use their own witnesses against Christians. And we decree those to be struck with anathema whoever wishes to prefer Jews in this part, since they ought to be subject to Christians and be cherished by them only for the sake of humanity. The gloss says regarding the right: no infidel ought to be admitted to testimony against a faithful one. For that, broadly, there is the canon 2nd question 7th chapter "Si hereticus," and the chapter "Non potest." The text says: He cannot be faithful toward men who has been infidel toward God. It declares this about Jews and other infidels. Thus, the laws admit to Jews that they can act, and they are to be convened at our judges, not at their elders.
