Sts Cyril and Methodius

Cyril and Methodius were well-educated brothers who both became priests.  They lived in an area of Greece where many people from the Slavic countries in Europe had moved.  Growing up, they spoke Greek but also learned the Slavic language too.  Both Fr. Cyril and Fr. Methodius loved to share the Good News of Jesus.  When the Prince of Moravia asked for missionaries to come and teach his people in the Slavic nations about Jesus, Fr. Cyril and Fr. Methodius knew this was their calling because they already spoke the language.
These brothers translated the Bible and the Mass into the Slavic language so the people could understand the teachings of Jesus. St. Cyril and St. Methodius are remembered for all the work they did to unite the Western and Eastern Christian churches.  They are also considered the patron saints of Europe, along with St. Benedict.
