Angelic Trisagion

The Holy Trinity is the central mystery of our faith. The feast of the Holy Trinity, which is celebrated on the Sunday after Pentecost, was established for the whole Western Church in 1134 by pope John XII. The Angelic Trisagion is said for the three days prior to Trinity Sunday.

 

In the name of the Father, and of the Son, and of the Holy Spirit. Amen.

V. Lord, open my lips.
R. And my mouth shall declare your praise.
V. O God, come to my assistance.

R. O Lord, make haste to help me.
V. Glory be...
R. As it was...

In nómine Patris et Fílii et Spíritus Sancti. Amen.

V. Dómine, lábia mea apéries.
R. Et os meum annuntiábit laudem tuam.
V. Deus, in adiutórium meum inténde.

R. Dómine, ad adiuvándum me festína.
V. Glória Patri,...
R. Sicut erat...

DECADES:

All say the invocation, Holy is God (Sanctus Deus); afterwards, the Lord's Prayer is said as usual, with the priest (or whoever presides) answered by the people. Then, nine times whoever presides says the prayer To You, O Blessed Trinity
 

 

(Tibi Laus). Each time, the people answer with the prayer Holy, Holy, ... After the last repetition, the Glory Be is said.

Holy is God! Holy and strong! Holy Immortal One, have mercy on us.
Our Father.
V. To you, O BlessedTrinity, be praise and honor and thanksgiving, for ever and ever!
R. Holy, holy, holy Lord, God of hosts. Heaven and earth are filled with your glory.
V. Glory be...
R. As it was...

 

The second and third decades are said in the same way, beginning with the words: Holy is God (Sanctus Deus) . . .

Ant. God the Father unbegot­ten, only­-begotten Son, and Holy Spirit, the Comforter: holy and undivided Trinity, with all our hearts we acknowledge you:Glory to you for ever.

V. Let us bless the Father, and the Son with the Holy Spirit.
R. Be praised and exalted above all things for ever.


Let us pray.
Almighty, ever­-living God, who have permitted us, your servants, in our profession of the true faith, to acknowledge the glory of the eternal Trinity, and in the power of that majesty to adore the Unity, grant that, by steadfastness in this same faith, we may be ever guarded against all adversity. Through Christ our Lord.


R. Amen.
After this, all say:
Set us free, save us, vivify us, O Blessed Trinity!

 

 


 

 Sanctus Deus, Sanctus fortis, Sanctus immortális, miserére nobis.
Pater Noster.
V. Tibi laus, tibi glória, tibi gratiárum áctio in saécula sem­pitérna, O Beáta Trínitas.
R. Sanctus, Sanctus, Sanctus Dóminus Deus exer­cítuum. Pleni sunt cæli et terra glória tua.
V. Glória Patri,...
R. Sicut erat...


 

 

 

Ant. Te Deum Patrem ingénitum, te Fílium uni­génitum, te Spí­ritum Sanctum Paráclitum, sanctam et indi­víduam Trini­tátem, toto corde et ore confi­témur, laudámus, atque bene­dícimus: Tibi glória in saécula.
 

V. Benedicámus Patrem, et Fílium cum Sancto Spíritu.
R. Laudémus et superexaltémus eum in saécula.

Oremus.
Omnípotens sempitérne Deus, qui dedísti fámulis tuis in confessióne veræ fídei, ætérnæ Trinitátis glóriam agnóscere, et in poténtia maiestátis adoráre Unitátem: quaésumus, ut eiúsdem fídei firmitáte, ab ómnibus semper muniámur ad­vérsis. Per Christum Dóminum nostrum.
 

 

R. Amen.

Líbera nos, salva nos, vivífica nos, o Beáta Trínitas!
