What's that?
Mass is the Eucharistic celebration in the Latin liturgical rites
of the Roman Catholic Church. The term is used also of similar
celebrations in Old Catholic Churches, in the Anglo-Catholic
tradition of Anglicanism, in Lutheran churches, and in a small
number of High Church Methodist parishes. For the celebration of
the Eucharist in Eastern Churches, including those in full
communion with the Holy See, other terms such as the Divine
Liturgy, the Holy Qurbana and the Badarak are normally used. Most
Western denominations not in full communion with the Catholic
Church also usually prefer terms other than Mass.
