I’m always bothered by people who say that they are Catholics but they also hold one or more heretical believes despite the fact that they are aware that they are going against Rome. Some support female “priesthood”, some say that contraception is OK and some believe that abortion in acceptable in some case. But these people, by their disloyalty even further deny the true nature of the Church.
So am I correct to say that a Catholic is only the person who believes* to be 100% faithful to the teachings of the Magisterium? And the person who is simply not a Catholic but perhaps some pseudo-catholic protestant?
This seems to be supported by the Baltimore Catechism (#554):
Q.Could a person who denies only one article of our Faith be a Catholic?
A: A person who denies even one article of our Faith could not be a Catholic; for truth is one and we must accept it whole and entire or not at all.
- A person who holds who is ignorant of a certain teaching and is willing to chance once he finds out is a totally different case.
