There is no Orthodox Vatican. While the Ecumenical Patriarch of Constantinople is first among equals Orthodox church comprises self-governing canonical areas. The majority of Orthodox patriarchates fall under either Russian, Greek or Constantinople Patriarchates. The Orthodox Patriarchate of Ukraine has fallen under Russian Patriarchate since early modern times but the Patriarchate of Kyiv existed before Muscovite Patriarchate. There has been multiple attempts to return it under Greek Patriarchate with varying success but they have been separate although not recognized by Russian Patriarchate since 2018.

And that was probably as many times as I have ever written Patriarchate on one text.
