If you disagree with the church in some way (support gay marriage, don’t believe in the true presence in the Eucharist, don’t believe that contraception is a sin, etc) can you still be a real Catholic? Can you call yourself a real Catholic if you disagree with a fundamental teaching of the church?
I was just reading something today that said something like 25% of Catholics believe in transubstantiation and about 87% believe that you don’t have to believe in all Catholic teachings to be a Catholic. What do you think?
Through baptism, we indeed become members of the Church, the Mystical Body of Christ. Baptism confers an indelible spiritual mark on the soul of his belonging to Christ. But baptism requires a profession of faith. In the case of adults, this is done personally by the one being baptized. In the case of infants, this profession of faith is made through the God parents. Now faith is a “theological virtue by which we believe in God and **all **that he has said and revealed to us, and the Holy Church proposes for our belief, because he is truth itself.” (Catechism of the Catholic Church, #1814). Consequently, if you disagree or disbelieve a teaching of the Church such as on homosexual marriage, the true presence of Christ in the Eucharist, contraception, etc., you are commiting a sin against faith. Such a sin could be mortal whereby one would become a dead member of the Church. In other cases, it may be only venial. But in all cases it is an offense against God.
The 87% of catholics ( it is questionable whether this percentage is true or not) you mention that believe you don’t have to believe all catholic teachings simply do not know their faith and they are sinning against the virtue of faith.
