The purpose of this manuscript is twofold: first, to present the Divine Liturgy in such a way as to highlight its beauty and dignity, and second, to show the liturgy's necessity by making the connection between Christ's fulfillment of the entire Old Testament and the proclamation of this fulfillment by the liturgy. It is not accidental that the term "new testament" refers both to the canon of apostolic books arising after Christ's ministry and to the Holy Sacrament of the Altar. There is an integral connection between word and worship, between faith and the reception of the incarnate Christ. And just as the written New Testament is the word of God, and therefore the ultimate norm and rule for all of Christian life, so the new testament as sacrament, in Christ's blood, must be the heart of truly Christian worship, from which all other forms of devotion and piety flow.
