Corpus Christi falls on the first Thursday after Trinity Sunday (60 days after Easter). The festival of Corpus Christi celebrates the Eucharist as the body of Christ. The name 'Corpus Christi' is Latin for 'the body of Christ'. This jubilant festival is celebrated by Roman Catholics to proclaim the truth of the transubstantiation of bread and wine into the actual body of Christ during Mass.
In some countries in the world, Catholic churches still celebrate the festival, not only with a Mass, but also with a procession that carries the consecrated wafer through the streets as a public statement that the sacrifice of Christ was for the salvation of the whole world.
