That makes no sense.
Either a person is a Catholic, a member of the Church, or not.
Just as there are RINO's there are also Conservatives in name only as well as Catholics in name only. They include Kerry, Pelousy, Biden, Kennedy, etc....
One must distinguish.
Every person who was baptized in the Catholic Church is JURIDICALLY a Catholic forever, unless he leaves the Catholic by a FORMAL ACT.
There are many people who are, juridically, Catholics, but who believe nothing of the Catholic Faith, and practice nothing of the Catholic Faith except a few seleected, public rituals, such as going to Communion when there are cameras present, and having bishops (sometimes multiple bishops) at their televised funerals. These are called “Kennedys.”
They also go by the name of “Cuomo,” “Pelosi,” “Kerry,” “Biden,” and “Democrat.”
In the case of such “Catholics” it is perfectly appropriate to use “scare quotes.”
