Neither I like the term Catholicism, and I never used the word related to myself. I am Catholic, I view the world as Catholic men, my faith is Catholic faith and my life is intended to be Catholic life as much as possible. I am not a subscriber to an ideology.
I born into the influence of National Socialism, which was an ideology started by Hitler’s Mein Kampf. I spent 30+ years of my life under the Marxism which was an ideology started by the Communist Manifesto
If someone is really Catholic it is not because one accepts an ideology, belief system, but because one lives as Catholics live. Jesus Christ did not taught a systematic belief system, He required his disciples to follow Him. The first Christians were not distinguished by their ideology, but by their life as testimony that Christ is risen, and they follow His path.
Naturally by the time a belief system was developed, but for Catholics that was almost always secondary behind the life. After the Arianism and its daughter systems died out the next ideological heresy was the protestantism based on principles like Sola Fide, Sola Scriptura against the requirement of the fulness by the Catholic faith.
It is not an accident that the term Catholicism is used mostly by convert traditionalist (imho used first by Chesterton) for whom the faith, the orthodoxy is the center.
Imho the proper title for this forum would be ‘Traditional Catholic faith’.
A term could be an abstraction and as such simple a pointer to an abstract concept, in this case to the Catholic faith system. However we do not think in concepts, not in term, we think in words. And a word is much more than a pointer, it always has some taste, some emotion attached to the parts or the word. In this case the ism suggest the man made system of thoughts, something which is not our Catholic faith.
