Muslims and Jews were equated as blasphemers to bar them from public office

Evidence

Muslims and Jews are also associated in their supposed hostility toward Christians. Both, for Lateran IV, are “blasphemers”; members of both groups parade around in garish clothes during Holy Week, mocking Christians who express their ritual grief at Christ’s Passion. This hostility is specifically invoked to justify the prohibition from holding public office: a “blasphemer” must not be given any power over a Christian. A polemical view of Islam informs the decisions of Lateran IV: the council does not enumerate or distinguish between the different “blasphemies” of the Muslims or the Jews, but it affirms that they are sufficient to justify the exclusion of both from positions of authority. — John V. Tolan, Saracens, 1018 (#corroborates, via linked claim)

On the days of Lamentation and on Passion Sunday they [Saracens and Jews] shall not appear in public at all, because some of them on such days, so we have heard, do not blush to parade in their most elegant clothes and are not afraid to ridicule the Christians, who exhibit a memorial of the most holy Passion and display signs of grief. What we most strictly forbid is for them to venture to burst out at all in derision of the Redeemer. And as we ought not to ignore the insulting of Him who atoned for our sins, we order secular rulers to inflict condign punishment upon those who so venture, to restrain them from daring at all to blaspheme Him who was crucified for us. — John V.
