The essential elements of the public worship of the Catholic Church, in the Sacrifice of the Eucharist and the administration of the sacraments, are the same in all Catholic rites. What is called the "Mass" in the West is called "Divine Liturgy" in the Eastern Churches.
The rite celebrated at Nativity parish is the Byzantine rite, which originated in the ancient Church at Constantinople. The Liturgy of St. John Chrysostom is most often used within the Byzantine rite, but is not the only Liturgy available.
Worship in the Ukrainian Catholic Church is characterized by a great sense of God's holiness, a reverence for the sacred, a humble dependence on the power and mercy of God and faith in the intercessory power of the Mother of God and all the Saints. There is a strong tradition of congregational singing without instrumentation, with traditional melodies adopted to our liturgical texts. At Nativity parish, the majority of the Divine Liturgy is said in English, with some responses and prayers said in Ukrainian.
The Liturgy consists of three main parts:
The entire text of the Liturgy of St. John Chrysostom.
Prior to Divine Liturgy the priest prepares the bread and
wine which will be consecrated during the Liturgy of the
Eucharist.
Reciting Scripture passages from the Prophets and the
Gospels which speak of the sacrifice of Jesus Christ, he
cuts small loaves of leavened bread into smaller pieces
which will be distributed as Holy Communion. He remembers
and prays for the needs of the living and the deceased.
During the Liturgy of the Word the focus is on the
proclamation of the Gospel—the Good News of Jesus
Christ—as recorded in the Scriptures.
The major portions are as follows:
