No. 1
Lord, have mercy. Lord have mercy...
A to You, Lord. Amen.
No. 2
Glory to the Father, and to the Son, and to the Holy Spirit,
now and forever and unto ages of ages. Amen.
O only-begotten Son and Word of God, though being immortal,
for our salvation You willed to take flesh from the Holy
Mother of God and ever-Virgin Mary; without changing Yourself You
became man and were crucified, O Christ God, trampling
death with death; You, who are one of the Persons of the
Holy Trinity, glorified together with the Father and the
Holy Spirit, save us...
No. 4
Alleluia, alleluia, alleluia...
No. 5
Glory to You, Lord, glory to You... Lord, have mercy...
No. 6
We who mystically represent the Cherubim and
to the life-giving Trinity sing the hymn "Thrice Holy,"
depose now every worldly concern. Amen.
To receive the King of the universe invisibly escorted
by the angelic hosts... Alleluia, Alleluia, Alleluia.
No. 9
The mercy of peace, the sacrifice of praise...
It is with Your spirit... We have offered them to the Lord.
It is worthy and just to adore the Father, the Son, and the Holy
Spirit, consubstantial and invisible Trinity... Holy, holy,
holy is the Lord of hosts: heaven and earth
are full of His glory. Hosanna in the highest.
Blessed is He who comes in the name of the Lord.
Hosanna in the highest... Amen.
No. 10
To You we sing, to You we bless, to You we give thanks,
o Lord, and we pray to You, our God.
No. 11
It is truly right to glorify You, o Mother of God,
always blessed and all immaculate and Mother of our God.
You, more honorable than the Cherubim and incomparably more
glorious than the Seraphim, You who without shadow of corruption
bore the Word of God, You we magnify as true
Mother of God... Of all and of the whole world...
No. 14
Praise God in the heavens, praise Him in the highest places.
Alleluia, alleluia, alleluia.
(Translation by "Christian Russia")
