Theme:
The end or goal of the Divine Liturgy is the union of our life with
Christ. This is accomplished by our partaking of the Holy Eucharist
which makes the faithful holy.
To fully participate in this grace, we need to prepare by the means the Lord has given us: Scripture and prayer.
The rite of the divine service as a whole symbolizes, through the mysteries celebrated in it, the entire dispensation [economy] of the condescension for our salvation of our true God and Savior Jesus Christ.
— Theodore of Andida, Protheoria
Outline
Purpose and Goal
The essential act in the celebration of the holy mysteries is the transformation of the elements into the Divine Body and Blood; its aim is the sanctification of the faithful, who through these mysteries receive the remission of their sins and the inheritance of the kingdom of heaven.
— St Nicholas Cabasilas, Commentary on the Divine Liturgy
Scriptural Examples of Worship
In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said:
“Holy, holy, holy is the LORD of hosts;
the whole earth is full of his glory!”And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. And I said: “Woe is me! For I am undone; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!”
Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. And he touched my mouth and said: Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”
And I heard the voice of the Lord saying, Whom shall I send, and who will go for us?” Then I said, Here I am! Send me.”
— Isaiah 6.1–9
Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. Strive for peace with everyone, and for the holiness without which no one will see the Lord. See to it that no one fails to obtain the grace of God; that no “root of bitterness” springs up and causes trouble, and by it many become defiled; that no one is sexually immoral or unholy like Esau, who sold his birthright for a single meal. For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears.
For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given, “If even a beast touches the mountain, it shall be stoned.” Indeed, so terrifying was the sight that Moses said, “I tremble with fear.” But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
See that you do not refuse him who is speaking. For if they did not escape when they refused him who warned them on earth, much less will we escape if we reject him who warns from heaven. At that time his voice shook the earth, but now he has promised, “Yet once more I will shake not only the earth but also the heavens.” This phrase, “Yet once more,” indicates the removal of things that are shaken—that is, things that have been made—in order that the things that cannot be shaken may remain. Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe, for our God is a consuming fire.
— Hebrews 12.12–29
Preparations
As a preparation for, and contribution to, this act and this purpose we have prayers, psalms, and readings from Holy Scripture; in short, all the sacred acts and forms which are said and done before and after the consecration of the elements. While it is true that God freely gives us all holy things and that we bring him nothing, but that they are absolute graces, he does nevertheless necessarily require that we should be fit to receive and to preserve them; and he would not permit those who were not so disposed to be thus sanctified. It is in this way that he admits us to Baptism and Confirmation; in this way that he receives us at the divine banquet and allows us to participate at the solemn table. Christ, in his parable of the sower, has illustrated this way that God has of dealing with us. “A sower went forth,” he says, “to sow” — not to plough the earth, but to sow: thus showing that the work of preparation must be done by us. Therefore, since in order to obtain the effects of the divine mysteries we must approach them in a state of grace and properly prepared, it was necessary that these preparations should find a place in the order of the sacred rite: and, in fact, they are found there.
