As many probably know,
there was a schism within Eastern Orthodoxy in 2018/2019, when the Russian Orthodox Church (Moscow Patriarchate) held a synod which decided to sever ties with the Patriarchate of Constantinople (Ecumenical Patriarchate). The cause was that the EP believed it had the authority to grant "Autocephaly" to the churches in Ukraine (which the MP claims is Russian territory), while the MP said the EP did not have such unilateral authority. While we shouldn't be happy about such events, it does provide for some Catholic apologetics material when dealing with Eastern Orthodox. Here are some things to ponder.
