The Blessed Trinity is a mystery.

"Glory be to the Father, and to the Son, and to the Holy Spirit;
the God who is, who was, and who is to come." (Cf Revelation 1: 8).

Sunday of the 11th week in Ordinary Time is Solemnity of the Most Holy Trinity. God is Father, Son and Holy Spirit, so revealed our Lord Jesus Christ. So believes all who call themselves Christians and are baptized in the name of the Father and the Son and the Holy Spirit. Amen.

How do we go about describing the God who is One in Three and at the same time the most perfect Unity. I would rather trust what the Church teaches:

"The Trinity is a mystery of faith in the strict sense, one of the "mysteries that are hidden in God, which can never be known unless they are revealed by God". To be sure, God has left traces of his Trinitarian being in his work of creation and in his Revelation throughout the Old Testament. But his inmost Being as Holy Trinity is a mystery that is inaccessible to reason alone or even to Israel's faith before the Incarnation of God's Son and the sending of the Holy Spirit." (CCC 237).

"Blest be God the Father,
and the Only Begotten Son of God,
and also the Holy Spirit,
for he has shown us his merciful love." (Entrance Antiphon).
