Unfortunately, that is the way of most religionists. Protestants, muslims, jews -- many treat their religion as an ethnicity or an "identity" -- a club they joined at birth.
Christ pointed out that many are called but few enter by the narrow gate. To be a true Christian, "you must be born again" -- you must hear or read the scriptures, understand what you are committing to and give yourself heart, mind, soul and body. Few are willing.
They also like to call themselves “Recovering Catholics”. When one refers to him/herself as such at an AA meeting (which happens often), I spit on the floor and walk out. It wasn’t the Church that caused any of their problems.
