[De communione et conversatione Iudaeorum et Christianorum]

...take care not to allow the infants of the Jews to be nursed in their houses, since the customs of the Jews do not agree with ours, and they could easily, through continuous association and constant familiarity, incline the souls of the simple toward their own superstition and perfidy. In the countryside and outside their houses, services can be done for them, the gloss says, and chapter "Multorum," same title. A Christian can, however, have or buy a Jewish servant, who even if he remains baptized, the master can then manumit him by removing the price or out of piety. For this, see Innocent III, Extra de Iudaeis, chapter "Et si Iudaeos," where it is said: A Christian woman receives Jews, whom she has relegated to perpetual servitude through her own fault, and sustains their cohabitation. Yet they ought not to be ungrateful to us, so as to return to Christians for kindness, insults, and that reward which a nurse receives in her bosom and a fire in her own fold. The Pope says that when nurses take the venerable sacrament on the day of Passover, they pour out the milk three days before they nurse the children into the latrine; they omit other detestable things against the faith. Therefore, the faithful are to be feared, because they incur divine indignation when they suffer such things among them to the confusion of the faith; and it prohibits nurses and their family under penalty of excommunication, even on both sides.

Also, let no Jew presume to buy a Christian servant, for if he does so, the Christian is snatched into liberty with no price given. For this, there is Gregory, and it assumes the canon, chapter "Mancipia," 54th distinction. Christian servants, whoever is found to have bought a Jew note: context implies buying from a Jew into liberty according to the precepts of the laws, without any ambiguity, lead them forth, lest—which is absent—the Christian religion be polluted, subjected to Jews. Whence this distinction can be given for the family or servants of the Jews: the servant of the Jew is either home-born, that is, born from his handmaid, or bought. If he is home-born and wishes to become a Christian, he is immediately snatched into liberty without any price being given. A law says, Decretum Gratiani Decree of Gratian, 54th distinction, chapter "Fraternitatem." It is fitting that your fraternity be solicitous: if from the servitude of the Jews, namely their own Jews, not only the Jew, but also whoever of the pagans wishes to become a Christian, whenever his will has been made manifest; lest they have the power of selling the Jews through any trick or argument; but he who considers turning to the Christian faith, the text appears to cut off and continue to the next folio
