Current usage
"Roman Catholic" is generally used on its own to refer to individuals, and in compound forms to refer to worship, parishes, festivals, etc. Its usage has varied, depending on circumstances. It is sometimes also identified with one or other of the terms "Catholic", "Western Catholic" (equivalent to "Latin Catholic"), and "Roman-Rite Catholic"."Roman Catholic" and "Roman Rite Catholic"
When referring to worship, the term Roman Catholic is at times used to refer to the "Roman Rite", which is not a church but a form of liturgy. The Roman Rite is distinct from the liturgies of the Eastern Catholic Churches and also from other Western liturgical rites such as the Ambrosian Rite, which have a much smaller following than the Roman Rite.
An example of this usage is provided in the book Roman Catholic Worship: Trent to today states:
