The Christmas Proclamation is traditionally chanted during the Christmas midnight mass in the Roman Catholic Church. Originating from the Roman Martyrology, the proclamation attempts to place the birth of Christ within the context of salvation history. While the proclamation had been removed during the liturgical reforms following Vatican II, Pope John Paul II restored the usage of the Proclamation during the 1980 Papal Christmas midnight mass. Since then, many parishes re-instituted the Proclamation as well.
