Who are we as Ukrainian Catholic Church?
There are twenty-two distinct Churches which together form the Catholic Church: the Western or "Latin" Church, which nearly all Canadians are familiar with, and the Eastern Churches, of which there are a total of twenty-one. The Ukrainian Eastern Christianity took a firm root in Ukraine in 988 when Vladimir, Prince of Kyiv, embraced the Christian Faith and was baptized. Soon afterwards many missionaries from the Byzantine Empire arrived, having been sent by the Patriarch of Constantinople to preach the Gospel.
When the Church of Rome and the Church of Constantinople severed ties with one another in the 11th century, the Church in Ukraine gradually followed suit and finally gave up the bonds of unity with Rome. When Ukrainian Orthodox bishops met at a council in Brest-Litovsk in 1595, seven bishops decided to re-establish communion with Rome. Guaranteed that their Byzantine tradition and Liturgy would be respected and recognized by Rome, they and many priests and lay faithful were re-united with the See of Rome, while others continued to remain Orthodox.
In the 19th century many Ukrainian Catholics began to immigrate to North America, bringing their pastors, traditions and liturgy to Canada and the United States. Under Communist rule, Catholics in Ukraine were persecuted, with many being imprisoned and murdered; in 1945 all the Ukrainian Catholic bishops were arrested or killed.
Today the Ukrainian Catholic Church is the largest Eastern Catholic Church, with about 5 million faithful. It is led by His Beatitude Husar, Major Archbishop of Kyiv.
