The eleven disciples went to Galilee,
to the mountain to which Jesus had ordered them.
When they all saw him, they worshiped, but they doubted.
Then Jesus approached and said to them,
"All power in heaven and on earth has been given to me.
Go, therefore, and make disciples of all nations,
baptizing them in the name of the Father,
and of the Son, and of the Holy Spirit,
teaching them to observe all that I have commanded you.
And behold, I am with you always, until the end of the age."

The Trinitarian mystery is the center, the deepest and most profound tenet of our Christian faith. It separates us from all other faiths and is the cause between the separation of the Jews and the early Christians. It is a mystery because although we can grasp the concept of it, we cannot fully explain and exhaust its richness, much like we know that there is such a thing as the Pacific ocean but we cannot imagine in our minds its full expanse and depth.
Profound though it is, Jesus revealed it to us, that God is not only Father, but He is also Son, and is also Spirit. It is a sublime truth not because it describes God's relationship to us but because among the three Persons in the Trinity we see the greatest truth of God. God is love. Within Himself love is alive and dynamic because a relationship of love requires more than one person.
The image of the Trinity, therefore, does not just speak of One God in Three Divine Persons, but above all, it speaks to us that God is a family. That is the best human analogy we have of the Trinity. As a Church, we cannot but humbly ruminate on this mystery as we grow in its truth.
