In the (Roman) Catholic Church, the Pope is the boss. It doesn't matter what country you live in. If you are Catholic, you are part of one Communion which transcends national borders, and it has always been so, ever since the first Bishop ventured outside of the Roman Empire.
Are there any present-day protestant churches like this? (I'm asking about established ecclesiastic communions, not mission churches. And I'm not asking about other Catholic Communions such as the Greek Orthodox. I'm asking about Christian protestants).
The authority of protestant church leaders seems to always end at the border. Sometimes like-minded protestant leaders might meet in an international synod, but I have never heard of any such synod that had any real authority to impose its resolutions upon their faithful - these synods are are advisory only. They are not like Ecumenical Councils, which are binding upon all Catholics worlldwide.
Are there any truly worldwide protestant churches?
