Saints Cyril and Methodius – July 5, 2025

Saints Cyril and Methodius Day takes place on July 5. In 863, brothers Cyril and Methodius were invited to preach the gospel in the Slavonic language. To do so, they created the Cyrillic alphabet and translated the “Bible” and liturgical books into Slavonic, which, at that time, had no written form, hence their statuses as founders of Slavic literature — they were known as the “apostles of the Slavs.”

History of Saints Cyril and Methodius

Saints Cyril and Methodius were two brothers born in Thessalonica, Byzantine, in the 9th century. They belonged to a prominent Christian family. Their father was Greek and their mother was Bulgarian. In the year 860, Cyril and Methodius went as missionaries to present-day Ukraine, to get the Slavic peoples of Bulgaria, Great Moravia, and Pannonia to convert to Christianity
.
The brothers are also credited for inventing the Glagolitic alphabet. The Moravian prince Rastislav requested the two brothers to transcribe religious books from Greek into Old Bulgarian. The Glagolitic alphabet is assumed to be the predecessor to Cyrillic, which was named after Cyril. Interestingly enough, Cyril was known as Constantine. He adopted the religious name of Cyril only on his deathbed. Today, most Slavic countries, including Russia, use some version of the alphabet. That’s why Saints Cyril and Methodius Day is also known as Alphabet Day.

In 1880, Pope Leo XIII decided to introduce their feast into the calendar of the Roman Catholic Church. In 1980, Pope John Paul II declared them co-patron saints of Europe. In the Czech Republic, Saints Cyril and Methodius Day is one of the biggest religious events of the year. The day is observed by undertaking the annual pilgrimage mass in Velehrad. The pilgrimage marks the anniversary of the arrival of missionaries, including Saints Cyril and Methodius, to Great Moravia in 863 A.D. While Saints Cyril and Methodius Day is also celebrated in other countries, the day has special historical, cultural, and religious significance to the people of Slovakia.
