In Coena Domini
In Coena Domini, ei Papal bull, originally promulgated in the Middle Ages, which received its final form from Urban VIII. in 1627. It was so called because originally it was read on Maundy Thursday, the day of the "Supper of the Lord." It contained a summary of the claims of the Roman Church, and excommunicated those who infringe her rights or dispute her doctrines. Clement XIV. discontinued its publication in 1773.
