The Holy Catholic Church is comprised of particular churches in communion with the pope. If a local church isn’t in communion with the pope, it isn’t part of the Holy Catholic Church.
Within the Holy Catholic Church there are a number of individual or particular churches, belonging to ancient rites. One of these is the Roman or Latin rite to which the Roman church belongs. It includes most of the Catholics in the Western world. A Roman Catholic is a Catholic who is a member of the Roman rite.
There are also many Catholics in the East who are not Roman Catholics, such as Maronite Catholics, Ukrainian Catholics, and Chaldean Catholics. These are all in communion with the pope, but they are not members of the Roman rite, so they are not Roman Catholics.
The Roman rite is not stricter than these other rights. They are equal. They all teach the same faith; it is only local customs that are different among them.
