Saints Cyril and Methodius, Apostles to the Slavs

The brothers who created the Slavonic alphabet and brought Christianity to the Slavic peoples
Saints Cyril and Methodius (9th century) were brothers, missionaries, and scholars who brought Christianity to the Slavic peoples and created the first Slavonic alphabet. Their work laid the foundation for Slavic Christianity and culture, earning them the title “Apostles to the Slavs” and “Equal-to-the-Apostles.”
The brothers were born in Thessalonica (modern Thessaloniki, Greece) to a prominent family. Methodius, the elder, was born around 815 AD, and Constantine (who later took the monastic name Cyril) around 827 AD. Their father was a high-ranking Byzantine official, and they grew up in a bilingual environment, speaking both Greek and a Slavic dialect.
Methodius initially pursued a military and administrative career, serving as governor of a Slavic province. Constantine, the younger and more scholarly brother, studied in Constantinople under the finest teachers, including Photios (later Patriarch). He became a brilliant linguist, philosopher, and theologian, earning the nickname “the Philosopher.”
Before their famous Slavic mission, the brothers worked together on other assignments. In 860-861, they traveled to the Khazars (in the Caucasus region) on a diplomatic and missionary journey. During this trip, they reportedly discovered the relics of Pope Saint Clement of Rome in the Crimea, which they later brought to Rome.
Constantine also engaged in theological debates with Muslims and Jews, demonstrating his intellectual prowess and missionary zeal. These early experiences prepared the brothers for their greatest work.
In 862 AD, Prince Rastislav of Great Moravia (modern Czech Republic and Slovakia) requested that the Byzantine Emperor send missionaries who could teach Christianity in the Slavic language. The German missionaries already in Moravia used Latin, which the people couldn’t understand, and Rastislav wanted his people to have the faith in their own tongue.
Emperor Michael III and Patriarch Photios chose Cyril and Methodius for this crucial mission. The brothers understood that effective evangelization required the Gospel in the people’s language. But there was a problem: Slavic had no written form.
Cyril’s solution was revolutionary: he created an alphabet for the Slavic language. Drawing on Greek letters and adding new characters for Slavic sounds, he developed what is now called the Glagolitic alphabet (the Cyrillic alphabet, named after Cyril, came later and was based on his work).
This was more than a technical achievement—it was a theological statement. Cyril believed that every people had the right to worship God and read Scripture in their own language. This put him at odds with the “three language theory” popular in the West, which held that only Hebrew, Greek, and Latin were suitable for liturgy and Scripture.
Once the alphabet was created, the brothers began translating. They started with the Gospels and the liturgical texts needed for worship. Their translations were not merely literal but sought to convey the meaning and beauty of the original texts in a way Slavic speakers could understand and appreciate.
This translation work was groundbreaking. For the first time, Slavic peoples could hear the Gospel, participate in the liturgy, and read Scripture in their own language. The impact on Slavic culture and identity cannot be overstated—Cyril and Methodius essentially created Slavic literary culture.
The brothers’ work faced fierce opposition from German missionaries and bishops who saw the use of Slavonic in the liturgy as heretical. They were summoned to Rome to defend their methods before Pope Hadrian II.
The brothers brought with them the relics of Saint Clement, which they presented to the Pope. Hadrian, impressed by their work and moved by the gift of the relics, approved the Slavonic liturgy. He even had the Slavonic liturgy celebrated in several Roman churches.
While in Rome, Constantine fell ill. He took monastic vows, receiving the name Cyril, and died on February 14, 869 AD, at about 42 years old. He was buried in Rome in the Church of San Clemente, where his relics remain.
Cyril’s last words to Methodius were reported to be: “Brother, you and I have shared the same destiny, plowing the same furrow. Now I fall in the field at the end of my day. I know you love your mountain solitude, but do not for its sake abandon our mission. Where better could you win salvation?”
Methodius returned to Moravia and was consecrated Archbishop of Sirmium (with jurisdiction over Moravia and Pannonia). He continued the translation work, completing the entire Bible in Slavonic and translating other important texts.
Methodius faced renewed opposition from German bishops, who had him imprisoned for over two years. Pope John VIII eventually secured his release and reaffirmed the legitimacy of the Slavonic liturgy, though with some restrictions.
Despite these trials, Methodius persevered. He trained disciples who would carry on the work, including Saints Clement and Naum, who later brought the Slavonic liturgy to Bulgaria and beyond.
Methodius died on April 6, 885 AD, in Moravia. His disciples were soon expelled by German-backed rulers, but the seeds had been planted. The Slavonic liturgy and literature flourished in Bulgaria, Serbia, and eventually Russia.
The impact of Cyril and Methodius on Slavic Christianity and culture is immeasurable:
Linguistic: They created the first Slavic alphabet and literary language, making possible all subsequent Slavic literature.
Liturgical: They established the principle that people should worship in their own language, a principle that remains central to Orthodox practice.
Cultural: They helped forge Slavic cultural identity, showing that Slavic peoples could have their own Christian civilization, not merely imitate Greek or Latin models.
Missionary: They demonstrated that effective evangelization requires cultural sensitivity and adaptation, not cultural imperialism.
Saints Cyril and Methodius are commemorated on May 11 in the Orthodox Church. They are patron saints of Europe (declared by Pope John Paul II in 1980), of ecumenism, and of Slavic peoples. They are especially venerated in Russia, Bulgaria, Czech Republic, Slovakia, and other Slavic nations.
The brothers’ work teaches us several crucial lessons:
First, the Gospel is for all peoples in all languages. God doesn’t require us to abandon our culture to follow Him, but rather to offer our culture to Him for transformation.
Second, evangelization requires both faithfulness to the message and sensitivity to the audience. Cyril and Methodius didn’t change the Gospel, but they made it accessible.
Third, true mission work often faces opposition, even from within the Church. The brothers persevered despite criticism and persecution, trusting that God would vindicate their work.
Finally, the work of evangelization often bears fruit long after the missionaries are gone. Cyril and Methodius didn’t live to see the full flowering of Slavic Christianity, but their work made it possible.
Their feast day reminds us that bringing the Gospel to new peoples requires both courage and creativity, faithfulness and flexibility, and above all, love for those we serve.
