Odd article at American Catholic—not a site I’m familiar with.
As you say, veneration of St. Cecilia goes back a very long way. Just because we cannot find archaeological evidence for the whole story hardly means that it’s not true.
Look at the home page of American Catholic.
American Catholic site is a step child of St Anthony Messenger Press. ST Anthony Messenger Press is ‘liberal/modernistic Catholic’. I looked at a couple of other saints on there, they seem to take a modernistic approach, wringing out all or much of folklore from the hagiography of older famous saints. They pretty much wring the stories dry. I find this even less attractive than hagiography and certainly less inspiring and informative.
Although I find myself doing much the same thing when reading hagiographies—mental balancing folklore vs truth, these people have an agenda.
