Trinity Sunday is an invitation to remember that
“[being] Christian is not the result of an ethical choice or a
lofty idea, but the encounter with an event, a person, which
gives life a new horizon and a decisive direction” (Deus Cari-
tas Est 1). In revealing himself as Trinitarian, God hasn’t mere-
ly shared impersonal facts about Himself; rather, God has
shared Himself with us, and has invited us into His own inner
life and communion of love, which alone is the origin, goal,
and meaning of our life. As we read in the Catechism, “By
sending His only Son and the Spirit of Love in the fullness of
time, God has revealed His innermost secret: God Himself is
an eternal exchange of love, Father, Son and Holy Spirit, and
He has destined us to share in that exchange” (CCC 221). On
Trinity Sunday, the Church proclaims the truth about God—
that God is love (1 John 4:8)—and the truth about us: we are
made for this love. We eternally belong to God—we have an
eternal home!

St. Elizabeth of the Trinity leads us more deeply into
this reality by saying that “The Trinity—this is our dwelling,
our ‘home,’ the Father’s house that we must never leave.”
When speaking with His disciples before His Passion, Jesus
directed the gaze of their hearts towards this truth: “In my
Father’s house there are many rooms…and when I go and
prepare a place for you, I will come again and will take you to
myself, that where I am you may be also” (John 14:2-3). Jesus
continued to reveal more of the Father’s loving plan: “I will
not leave you orphans; I will come to you…If a man loves Me,
he will keep My Word, and My Father will love him, and we
will come to him and make our home with him” (John 14:18,
23). Jesus reveals to His disciples the Father’s breathtaking
desire. He desires not only that we be at home in Him when
we get to heaven in the future, but He desires us to be at home
in Him now—and so, He comes to us, He makes His home
among us (c.f., John 1:14) in order to make His home in us.
Thus, with the Feast of Pentecost and the sending of the Holy
Spirit, God fulfills His promise to never leave us orphans. This
is why the Church celebrates Trinity Sunday the week after
Pentecost: On Pentecost, “the Holy Trinity is fully re-
vealed” (CCC 732).

“I will not leave you orphans!” If Jesus has promised to
never leave us orphans, then that means we have a permanent
home—we eternally belong to the Father as children of His
heavenly household! This is the mystery into which the
Church invites us more deeply on the Solemnity of the Most
Holy Trinity. Yet this truth is also the very gift that that we are
invited to share with all whom God entrusts to us in our daily
lives: “Love one another as I have loved you” (John 15:12).
Every human heart longs for its eternal home. Today, we in-
vite the Trinity to be more at home in our hearts in order to
make them a more welcoming home for others—that through
our smile, our gentleness, our availability of heart, everyone
whom the Father entrusts to us may experience the Love that
is their eternal home.

Question for Reflection: Today, will we allow our
hearts to be touched and changed by the reality into
which Trinity Sunday invites us more deeply?
