Preface of the Most Holy Trinity: [The mystery of the Most Holy Trinity]

It is truly right and just, our duty and our salvation,
always and everywhere to give you thanks,
Lord, holy Father, almighty and eternal God.

For with your Only Begotten Son and the Holy Spirit
you are one God, one Lord:
not in the unity of a single person,
but in a Trinity of one substance.

For what you have revealed to us of your glory
we believe equally of your Son
and of the Holy Spirit,
so that, in the confessing of the true and eternal Godhead,
you might be adored in what is proper to each Person,
their unity in substance,
and their equality in majesty.

For this is praised by the Angels and Archangels,
Cherubim, too, and Seraphim,
who never cease to cry out each day,
as with one voice they acclaim:

Holy, Holy, Holy Lord God of hosts…

Communion Antiphon:

Since you are children of God,
God has sent into your hearts the Spirit of his Son,
the Spirit who cries out: Abba, Father. Galatians 4:6 [Roman Missal]
