Pope Pius V reverses the liberal policies of his predecessor and confirms the bull of Pope Paul IV, Cum nimis absurdum.
Pope Pius V has the Jews confined to ghettos with one synagogue, forbids them from owning real estate, forbids them from working on Sundays, denies them from having Christian servants or nurses, forbids them from acting as doctors for Christians, forbids them from testifying against Christians, forbids them from fraternizing or eating with Christians, and forces them to wear special yellow caps in public. Violations of any of these items is made a crime.
The introduction to speaks volumes about the Catholic attitude towards Jews:
"Since it is completely senseless and inappropriate to be in a situation where Christian piety allows the Jews (whose guilt — all of their own doing — has condemned them to eternal slavery) access to our society and even to live among us; indeed, they are without gratitude to Christians, as, instead of thanks for gracious treatment, they return invective, and among themselves, instead of the slavery, which they deserve, they manage to claim superiority: we, who recently learned that these very Jews have insolently invaded Rome from a number of the Papal States, territories and domains, to the extent that not only have they mingled with Christians (even when close to their churches) and wearing no identifying garments, but to dwell in homes, indeed, even in the more noble [dwellings] of the states, territories and domains in which they lingered, conducting business from their houses and in the streets and dealing in real estate; they even have nurses and housemaids and other Christians as hired servants.
And they would dare to perpetrate a wide variety of other dishonorable things, contemptuous of the [very] name Christian.
Considering that the Church of Rome tolerates these very Jews (evidence of the true Christian faith) and to this end [we declare]: that they, won over by the piety and kindness of the See, should at long last recognize their erroneous ways, and should lose no time in seeing the true light of the catholic faith, and thus to agree that while they persist in their errors, realizing that they are slaves because of their deeds, whereas Christians have been freed through our Lord God Jesus Christ, and that it is unwarranted for it to appear that the sons of free women serve the sons of maids."
