Someone asked me, “Father, who is a Catholic?”
To be a Catholic – it is simple – follow Christ, His Church, and be obedient to the Magesterium, do not separate yourself from the Church by creating delusions that are not Catholic. How do you know if it is a delusion, and leading oneself away from holiness? Test it, test what people are telling you. Test what bishops, and priests are telling you. Go to the Catechism. See what it states about faith and morals. It is all there. Two thousand years of prayer, research, tradition, study, and living a Catholic life.
From the Cathecism; “[The] catechism … [presents]… an organic synthesis of the essential and fundamental contents of Catholic doctrine, as regards both faith and morals, in the light of the Second Vatican Council and the whole of the Church’s Tradition.
Be faithful to what we have received – You are either Catholic or you are not.
