Except it's really not. Most Protestant churches don't do that; no church I have ever even seen has EVER repeated the Nicene Creed, and I've never heard of anything close to the Four Marks.
I would give you karma, but what a religion is founded on and what it's modern day members practice are two entirely different things...Protestant's don't call them the Four Marks because by doing so, they would be openly deferring to the Roman Catholic Church...what they're called (or if all four are even identified separately) is up to each church...
The word catholic (note it is not capitalized) is by definition to belong to the UNIVERSAL church of Christ...how a church defines church and universal as well as who else is part of their club is their own business...
Hardly anyone ever uses the word "catholic" unless they are referring to the Roman Catholic Church...nevertheless, all church's of Christianity either A) assume they are a select group of acceptable churches (possibly only themselves) or B ) believe all "Christians" are Christians and all part of the same universal church...
You can argue semantics on how to define "church" and "congregation" and "Christian" but ultimately most of your Christian churches believe themselves to be the right church...whether they like to use the word catholic or not, repeat the Nicene Creed or not, etc. is really irrelevant...ultimately, every church claims to be in line with the original universal church of the apostles...
If a particular "church" has no prejudice or issues with any other Christian churches, then they are still part of the universal church, hence they are by definition catholic...the only difference is, they extend that "privilege" to others...
The meaning of catholic has been cannibalized by connotation just like the word liberal...the original definition still has it's use today but obviously most people never use the word in that manner...
The only way you could be remotely Christian but not catholic is if you claimed to believe in Christ as the son of God, but believed that the Apostles were all wrong...and since most of our knowledge of Christ is from the Apostles, you either are like L. Ron Hubbard founding a new religion or you have some divine inspiration the rest of humanity does not...if you find a church that believes Christ to be the son of God but claims the apostles got it all entirely wrong, then you can safely say they are not catholic...the only church I know of that comes even close to going against the apostles is the Mormons, and that is only because John Smith provided additional revelations that would supersede anything from the Apostles...
The point here wasn't to start a linguistic argument but to show the irony of Christian sect conflicts where each sect declares itself the one and only "correct" church...by technicality, all churches are catholic which just makes all of them seem like hypocritical bigots...
