Corpus Christi is a Catholic feast that is always celebrated on the second Thursday after Pentecost. In many Catholic parishes, a consecrated host in a gold-decorated vessel, the monstrance, is still carried through the streets as the body of Christ.

The procession is emblematic of the wandering people of God in the world with Christ in their midst. In non-Catholic areas, the festival is usually not celebrated. Martin Luther described the feast in 1527 as the "most harmful annual festival"
