"...your current Pope is so preoccupied with the political to the point that he’s been antithetical to Catholic doctrine."

Yes: that's, sadly, all too obviously true.

But the Vatican (Stato della Città del Vaticano) is not a state church. It is a city-state. It has its own postage stamps, currency, diplomatic corps, etc. The Catholic Church existed before the Stato della Città del Vaticano, and --- if ISIS managed, God forbid, to nuke it ---- will exist after "the Vatican" is gone.

The Church is not a state. What she is, --- well, see tagline.

The Roman Catholic Church has a seat in the United Nations. Ergo, the Roman Catholic Church is a State. It's a State that, as you helpfully note, issues its own postage stamps, currency, has its own diplomatic corps and laws. The Roman Catholic Church is the original State Church and remains so.

The Church is not a state. What she is, --- well, see tagline.

Church as used by Roman Catholics denotes a denomination. The word in your tagline is the ekklesia...the body of believers.

Also, your tagline is incorrect in that Church is not in caps in the Greek nor is it in caps in the vast majority of the major translations.

Even the Douay-Rheims doesn't put church in caps.
