In the name of the Father, and of the Son,
and of the Holy Spirit. Amen.
Glory to thee, our God, glory to thee.
O Heavenly King, the Comforter,
the Spirit of Truth,
who art everywhere present and fillest all things,
Treasury of good things and Giver of life,
come and abide in us,
cleanse us from every stain,
and save our souls, O Good One.
Holy God, Holy and Mighty,
Holy and Immortal, have mercy on us. (Three times)
Glory to the Father, and to the Son,
and to the Holy Spirit,
both now and ever and unto the ages of ages. Amen.
All-holy Trinity, have mercy on us.
Lord, cleanse us from our sins.
Master, pardon our iniquities.
Holy One, visit and heal our infirmities
for thy Name's sake.
Lord, have mercy. (Three times)
Glory to the Father, and to the Son,
and to the Holy Spirit,
both now and ever and unto the ages of ages. Amen.
Our Father, who art in heaven,
hallowed be thy Name.
Thy kingdom come.
Thy will be done,
on earth as it is in heaven.
Give us this day our daily bread;
and forgive us our trespasses,
as we forgive those who trespass against us;
and lead us not into temptation,
but deliver us from evil.
For thine is the kingdom,
and the power, and the glory,
of the Father, and of the Son,
and of the Holy Spirit,
now and ever and unto the ages of ages.
Amen.
The Trisagion Prayers
Also known as Orthodox Opening Prayers · Usual Beginning
About this prayer
The Trisagion Prayers are a set of brief prayers that open nearly every Orthodox service and are the standard beginning of private Orthodox prayer. They are called the Trisagion Prayers because the Trisagion ('Holy God, Holy and Mighty, Holy and Immortal, have mercy on us') is their central element. The full set includes the opening doxology, the Trisagion itself (said three times), a brief trinitarian doxology, the Theotokion, and the Lord's Prayer. This sequence is distinguished from the individual Trisagion prayer listed separately on this site: that page covers the single verse; this page covers the full sequence as used in Orthodox devotional practice. The Trisagion Prayers represent one of the most distinctive features of Orthodox Christian prayer, present at virtually every point of entry into Orthodox liturgical or private worship.
When it's said
The Trisagion Prayers open Orthodox Matins, Vespers, Compline, and most other services. They are the standard beginning for private morning and evening prayer. Orthodox Christians are taught to begin all prayer with this sequence. The sequence takes approximately two to three minutes to say at a measured pace.
Notes on the text
The prayer to the Holy Spirit ('O Heavenly King') is omitted from Pascha (Easter) through Pentecost, during which it is replaced by 'Christ is risen from the dead.' The Trisagion is said three times. The individual components of this sequence (the Trisagion, the Lord's Prayer, the Glory Be) are found on their own pages on this site.
