The worship of the Holy Trinity is the ultimate act of mankind, giving over our entire selves to God and becoming mystically united to Him through the celebration of the holy Mysteries/Sacraments. Worship of the One True God is the purpose of man's existence.
Worship in the Western Orthodox Christian Church is liturgical, that is, it follows a rhythm of ritualistic gestures and patterns that involve the whole person. Western Orthodox worship engages all the senses of the human person so that we can fully and completely give ourselves over to the mystical experience of communion with the Holy Trinity. Worship that is Western Orthodox is intended to be transformative, it is an encounter with the Divine One. Our worship, when fully entered into, will help to make persons holy, saints.
We worship the Father, the Son and the Holy Spirit, the Trinity one in substance and undivided. Worship is the adoration of God, distinct from veneration which is the respect we show toward holy people and things. The Holy Sacrifice of the Mass/Divine Liturgy is the central public act of worship in the Old Roman Catholic Church. Our Liturgical worship has a secondary value to it in that the prayers teach the Divine Faith and dogmas, serving to form the Faithful in the doctrinal teachings of Our Lord Jesus Christ and His Church.
The liturgical worship of the Western Orthodox Church will always serve to bring one out of the mundane things of the world and provide a foretaste of the Heavenly Banquet by raising the Christian to the heights of matters divine through the mystical ascent.
Other important liturgical celebrations of the Western Orthodox Christian Church include the praying of the Divine Office (Matins, Lauds, Prime, Terce, Sext, None, Vespers and Compline) which is the recitation of the psalms and reading selections from the Old/New Testaments, pious devotions, Benediction of the Most Blessed Sacrament, the holy Rosary, Novenas, etc.
