looks surprised

goes to check Dutch Wikipedia

https://nl.wikipedia.org/wiki/Katholicisme

Using Google Translate to convert the overview to English, I get:

Catholicism is considered the largest movement within Christianity. The term derives from the word "catholic" and comes from the Greek (καθολικός - katholikos), meaning general or universal. The term "catholic" was first used in the context of the church by Ignatius of Antioch. In a letter to the Christians of Smyrna in 107, he wrote: "Where Christ is, there is the Catholic Church."[1]

Catholicism is united by two creeds, the Apostles' Creed and the Nicene-Constantinopolitan Creed, and can be divided into:

Christians who unite under the Bishop of Rome (the Pope): Roman Catholics

Other Christians who call themselves Catholic

That sounds like they're classifying it the same way I'd normally see it in the English-speaking world.

I'm from New Jersey and we all make a very big distinction between Catholicism and Christian. And lots of us were raised Catholic around here, and Christians all seem to be late-in-life converts, at least where I'm from. And I'm a typical nothinger now, but I'd take Catholicism and it's bullshit (not kid touching) over what I've experienced with the Christians around here, never met a faker bunch of people.
