You don't get it. It doesn't matter if a power hasn't been used yet if it can be used. Geopolitical power is mostly about what you can do if pushed, not what you have done.
Medieval popes constantly used their ability to mobilize Catholics against their governments or foreign governments in diplomacy. It was part of the power of the papacy—at one point, if the pope excommunicated a king, the king was in real danger of losing the throne or at least had a serious political problem on his hands, as in the case of Philip IV of France, Frederick II of the Holy Roman Empire, and King John of England.
Popes of Rome even used their imaginary power to give people free tickets to Heaven to mobilize hoards of faithful, but spiritually blinded, Catholics to go to war with other Christian nations during the Fourth Crusade.
However even if you deny every single one of my historical examples, the very fact that the Pope can declare a crusade against a nation, and that the faithful actually believed they were at risk of Hell unless they joined his army, means that pious Catholics are more faithful to the Vatican than to their nation.
His Kingdom is not of this world.
Luckily, as written, very few Catholics are pious in this way anymore. The pope could never get away with using this power as he could have in medieval Europe. That ship has sailed, now he's just a man in a wizard costume who preaches environmentalism, anti-proselytism, tolerance, and liberal values.
