Josaphat followed the Metropolitan Archbishop of Kiev and a group of Ukrainian and Belorussian bishops who entered into full communion with Rome in 1598. The “Union of Brest” preserved the Byzantine liturgy and the spirituality and practices of the Byzantine tradition while also recognizing the juridical primacy of the Bishop of Rome for the Universal Church. From this reunion were born what are today known as the Ukrainian Byzantine Catholic Church and the Ruthenian Byzantine Catholic Church.
At the beginning of the Seventeenth Century, the reunion was an occasion of great controversy among the population and clergy. Josaphat himself became a Byzantine Catholic Bishop and worked tirelessly not only in defense of the Papacy, but also to reform the clergy according to the great heritage of the Eastern Church and to catechize the common people and serve them. Many were drawn by his preaching as well as his humility and holiness, but others opposed him vehemently, preferring the benefits of patronage that local nobility gave to the orthodox churches.
Saint Josaphat sought Church unity with great fervor, but also great charity. He knew that his enemies were plotting his death, yet he remained among his people to guide them and, as much as possible, resolve disputes and overcome the violence of his enemies with the nonviolence of Christian love.
On November 12, 1623, he was put to death by a lynch mob of his enemies.
“You people want to kill me. You wait in ambush for me in the streets, on the bridges, on the highways, in the marketplace, everywhere. Here I am; I came to you as a Shepherd. You know I would be happy to give my life for you. I am ready to die for union of the Church under Saint Peter and his successor, the Pope” (Saint Josaphat).
Saint Josaphat, pray for us. Pray for the unity of all Christians. Pray for the reunion of Christians East and West. Pray for a just and lasting peace for the people of Ukraine, and a renewal of their fidelity to Jesus Christ and commitment to human dignity.
