There may not be enough institutional knowledge at CNN about Catholicism that the editors would know that there is a difference between a basilica and a cathedral.
This is the sort of thing that the folks at GetReligion.com were trying to address: not advocating any particular religion, but helping newsrooms ‘get’ religion, in the senses of understanding it and of not getting things wrong. The example at https://www.getreligion.org/getreligion/2023/12/29/why-we-di... is a really good one: the New York Times in 2014 published ‘the vast Church of the Holy Sepulcher marking the site where many Christians believe that Jesus is buried.’ There was no-one on the editorial team that handled that article who knew enough about Christianity to know that Christians don’t believe Jesus is buried anywhere.
