Holy Protection Byzantine Catholic Church, Denver Colorado

This is Holy Protection Byzantine Catholic Church in Denver Colorado.

Many people, when they hear the word "Catholic", immediately have what, in the English speaking world, are frequently referred to as "Roman Catholics" in mind.  In fact, however, "Roman" Catholics are Latin Rite Catholics whose churches use the Roman Rite.  Roman Catholics make up the overwhelming majority of Catholics, and indeed the majority of Catholics, on earth.

They aren't the only Catholics however.   The Roman Rite itself is just one of several Latin, or Western, Rites.  There are also several Eastern Rites, of which the Byzantine Rite is one.

The Byzantine Catholic Church, which is also called the Ruthenian Byzantine Catholic Church, uses the same liturgical rite as the Greek Orthodox Church and shares the same calendar.  It dates back to the conversion of the Rusyn people in the Carpathians to Christianity in the 9th Century.  That work, done by St. Cyril and St. Methodius brought to the Rusyn people the form of worship in the Eastern Rite.  They Rusyn church initially followed the Orthodox Churches following  the schism of 1054, but in 1645 the Ruthenian Church started to return to communion with Rome, resulting in the Rutenian Byzantine Catholic Church, which is normally called the Byzantine Catholic Church in the United States.

Immigration from Eastern Europe brought the Church into the United States. Originally a strongly ethnic church, in recent decades it has become multi ethnic and its strongly traditional character has caused it to obtain new members from both very conservative Latin Rite Catholics as well as very conservative former Protestants.  Indeed, while this church is very small, it has been growing and now has a Byzantine Catholic outreach to Ft. Collins, Colorado, where it holds services in Roman Catholic Churches.
