So how does a Maronite mass differ from another order?
The Catholic Church is comprised of 22 churches - 1 Western (Latin) and 21 Eastern. Although there are 22 Churches, there are only eight "Rites" that are used among them. A Rite is a "liturgical, theological, spiritual and disciplinary patrimony," (Code of Canons of the Eastern Churches, canon 28). "Rite" best refers to the liturgical and disciplinary traditions used in celebrating the sacraments. Many Eastern Catholic Churches use the same Rite, although they are distinct autonomous Churches. For example, the Ukrainian Catholic Church and the Melkite Catholic Church are distinct Churches with their own hierarchies. Yet they both use the Byzantine Rite.
