Of course, there are several legitimated rites in the Catholic Church.
These are divided in two great families: the Western rites and the Eastern rites. The Roman Rite belongs to the first family: the Western rites, and is the most common one.
What do you mean with Roman Liturgy?
The liturgy is the public worship that the Church, Mystical Body of Jesus-Christ, renders to God.
We specify Roman Liturgy to express this website is dedicated to the study the ordinary form of the Roman Rite of the Roman Catholic Church, currently in use.
It is the rite celebrated by the Bishop of Rome, since Pope Paul VI, and is used in Western Europe, whole America and Oceany, a great part of Africa, and several parts of Asia.
