In Cæna Domini

In Cæna Domini (i.e. in the Supper of the Lord), a papal bull promulgated in the Middle Ages, denouncing excommunication against all who dispute the claims of the Church, and the promulgation of which was felt on all hands to be intolerable; the promulgation has been discontinued since 1773.
