“In the name of the Father, and of the Son and of the Holy Spirit.” Christians hear those words, the trinitarian formula, so many times in our lives of worship that we don’t always stop to think of what that means. Our God is a trinity: Father, Son and Holy Spirit. All in one.

Today is Trinity Sunday, a day set aside in the liturgical calendar to consider and emphasize the worship of this Holy Trinity.

Here are four Bible verses and one prayer for this holy day.

Bible Verses

But it is God who establishes us with you in Christ, and has commissioned us; he has put his seal upon us and given us his Spirit in our hearts as a guarantee. (2 Corinthians 1:21-22)

Prayer to the Holy Trinity

Glory be to the Father,
Who by His almighty power and love created me,
making me in the image and likeness of God.

“Throne of Mercy”, Albrecht Dürer, 1511

Glory be to the Son,
Who by His Precious Blood delivered me from hell,
and opened for me the gates of heaven.

Glory be to the Holy Spirit,
Who has sanctified me in the sacrament of Baptism,
and continues to sanctify me
by the graces I receive daily from His bounty.

Glory be to the Three adorable Persons of the Holy Trinity,
now and forever.

Amen.
