During the chanting of the dogmatic theotokion, the gates which we closed at the end of the proemial psalm are opened again. The opening of the gates represents the opening of entry into the Kingdom of heaven to people by the coming of Jesus Christ on earth. As the Light of Heaven is represented by the altar, so again it is opened unto the people. The priest and deacon come out of the sanctuary onto the soleas, thus signifying Jesus Christ’s appearance for the salvation of man. The procession of the clergy at this point is one of the most solemn moments in the Vigil and is called the Vespers Entrance, and it is made carrying the censer. When on the soleas, the deacon asks the priest’s blessing for the holy entrance, and then with the censer makes the sign of the Cross over the Royal Gates and exclaims, “Wisdom, Upright!” As in the Liturgy, the exclamation of the word, Wisdom, is to inspire the people to pay especial attention to the significance of the action taking place. The worshippers, seeing the light flowing from the sanctuary and representing that of Christ Jesus, Who came to the people, reverently greet Him with the hymn:-
O Joyous Light of the holy glory of the immortal, heavenly,
holy, blessed Father, O Jesus Christ: We that come to the setting
of the sun, when we behold the evening light praise
Father, Son and Holy Spirit, God.
Meet it is for Thee at all times to be praised with gladsome voices,
O Son of God, Giver of life.
Wherefore, the world doth glorify Thee.
Comparing Jesus Christ to light shows that through His teaching Jesus Christ led people out of a condition of spiritual gloom and ignorance and led them into God’s righteousness.
Then follows the prokeimenon, that is an exchange of verses which are taken from the psalms. For each day of the week there is a specially appointed prokeimenon, chosen to express the particular sacred commemoration of that day. Thus for Sundays (Saturday evening Vespers), we have: The Lord is King, He is clothed with majesty.
This psalmic verse and those which follow it tell us that the Lord is glorified in the beauty of His royalty, that His vesture betokens His majesty. Under the power of His hand He has not only all the universe, but His house which is His Church. And He will maintain this holiness unto length of days. Furthermore it leads us to another thought: - The Lord is reigning, that is that His Kingdom is coming and all creation, both the world and man, will be clothed in beauty, it will be renewed and reborn.
On Sunday evening for Monday, we have: Behold now, bless ye the Lord, all ye servants of the Lord.
On Monday evening for Tuesday, we have: The Lord will hearken unto me when I cry unto Him.
On Tuesday evening for Wednesday, we have: Thy mercy shall pursue me, O Lord, all the days of my life.
On Wednesday evening for Thursday, we have: O God, in Thy Name save me, and in Thy strength do Thou judge me.
On Thursday evening for Friday, we have: My help cometh from the Lord, Who hath made heaven and the earth.
On Friday evening for Saturday, we have: O God, Thou art my helper; Thy mercy shall go before me.
