Introduction
Throughout the liturgical year, the Church’s celebrations focus largely on what God has done: the Incarnation, the Passion and Resurrection, the sending of the Holy Spirit.
After reflecting on the whole drama of salvation, the Church pauses to contemplate a deeper question: Who is the God acting in all these events?
The answer is the Trinity: Father, Son, and Holy Spirit — one God in three Persons. This mystery stands at the heart of Christian faith, shaping theology, worship, prayer, and even the Christian understanding of love itself.
The dogma of faith celebrated in this solemnity is this: There is one God, and in this one God there are three Divine Persons; the Father is God, the Son is God, the Holy Spirit is God. Yet there are not three Gods, but one, eternal, incomprehensible God.
1st Reading – Exodus 34:4b-6, 8-9
Early in the morning Moses went up Mount Sinai
as the LORD had commanded him,
taking along the two stone tablets.
Having come down in a cloud, the LORD stood with Moses there
and proclaimed his name, “LORD.”
Thus the LORD passed before him and cried out,
“The LORD, the LORD, a merciful and gracious God,
slow to anger and rich in kindness and fidelity.”
Moses at once bowed down to the ground in worship.
Then he said, “If I find favor with you, O Lord,
do come along in our company.
This is indeed a stiff-necked people; yet pardon our wickedness and sins,
and receive us as your own.”
Today’s first reading presents God the Father revealing his own inner identity. He proclaims his name to Moses, emphasizing mercy, patience, and covenant love.
Early in the morning Moses went up Mount Sinai as the LORD had commanded him, taking along the two stone tablets.
This is Moses’ return to Mount Sinai after the covenant was broken in the golden calf incident. In anger at the people’s idolatry, Moses had shattered the first tablets of the covenant (Exodus 32:19). Yet after Moses interceded for the people, God called him once more up the mountain to renew the covenant, now with replacement tablets prepared by Moses (Exodus 34:1-4).
This event on Mount Sinai will be a significant turning point in the relationship between God and the Israelites, revealing profound insights into God’s character, mercy, and faithfulness.
Having come down in a cloud,
The cloud both reveals and conceals the divine presence.
Throughout Israel’s journey in the wilderness, God led his people in a pillar of cloud by day (Exodus 13:21). The cloud signifies that God is truly present, yet still beyond the full comprehension of man.
the LORD stood with him there and proclaimed his name, “LORD.”
Unbidden, God graciously reveals his personal name: YHWH.
In most English Bibles, YWHW is rendered as “LORD” because of a longstanding Jewish tradition: out of reverence for the holiness of the divine name, it was not pronounced aloud, and readers substituted a title such as “Adonai” (“Lord”) instead.
Thus the LORD passed before him and cried out, “The LORD, the LORD, a merciful and gracious God, slow to anger and rich in kindness and fidelity.”
God explains what his own name means, and in so doing reveals his divine essence. (Recall that in the Hebrew tradition, names encapsulate the essence of a person.)
This proclamation became one of the great creedal statements of Israel’s faith, echoed throughout the Old Testament (Psalm 86:15; Psalm 103:8; Joel 2:13; Jonah 4:2).
The attributes God uses to describe himself are profoundly relational and covenantal:
- “Merciful” (rahûm) is womb love, the kind of attachment one has for the child of one’s own body, or for a sibling born from the same womb.
- “Gracious” (hannûn) is frequently used as a synonym for compassionate or merciful.
- God is “slow to anger,” reluctant to rain divine wrath on those who have violated the covenant relationship.
- “Lovingkindness” (hesed) and “fidelity” (ĕmet) characterize the steadfastness with which God clings to the covenant partners.
These dispositions show God’s intention to remain faithful to his covenant relationship with the people, which is remarkable in light of the Israelites’ profound betrayal in the golden calf incident.
Moses at once bowed down to the ground in worship.
Moses responds as every encounter with God demands: with humility, reverence, and worship.
Then he said, “If I find favor with you, O Lord, do come along in our company. This is indeed a stiff-necked people; yet pardon our wickedness and sins, and receive us as your own.”
Moses once more pleads for the people, leveraging the favor (hēn) he trusts he has in God’s eyes. While acknowledging that the people are difficult and stubborn, he boldly makes a threefold request: stay with us, forgive us, receive us as your own.
Notice how he identifies with the people, despite their many shortcomings: “our company,” “our wickedness,” “receive us.”
Moses’ request that God “receive us as your own” is interesting since God had already chosen the people of Israel and entered into a covenant with them. After the Israelites’ grave misstep in the golden calf incident, Moses pleads for the relationship to be restored and renewed.
The passage ultimately reveals a God whose mercy is greater than human sin. God remains steadfast even when his people falter.
2nd Reading – 2 Corinthians 13:11-13
Brothers and sisters, rejoice.
Mend your ways, encourage one another,
agree with one another, live in peace,
and the God of love and peace will be with you.
Greet one another with a holy kiss.
All the holy ones greet you.
The grace of the Lord Jesus Christ
and the love of God
and the fellowship of the Holy Spirit be with all of you.
Today’s second reading contains one of the clearest explicit Trinitarian formulas in Scripture.
Brothers and sisters, rejoice.
These are the closing verses of Saint Paul’s second letter to the Corinthians. His farewell begins with a summons to rejoice.
The joy he is exhorting them to isn’t simply delight, but a deep and abiding joy in Christ Jesus that transcends external circumstances.
Mend your ways, encourage one another, agree with one another, live in peace,
This directive suggests that their behavior has not been aligned with their commitment to Christ.
and the God of love and peace will be with you.
By heeding Paul’s advice, the Corinthians will encounter the loving and peaceful presence of God.
God’s presence is not a reward for faithfulness; Paul consistently emphasizes that it is through God’s grace that Christians are empowered to be faithful in the first place.
However, it’s incumbent upon us to respond to this grace to fully experience the love and peace that God desires to bestow upon us.
Greet one another with a holy kiss.
In the East, kissing was a common way of greeting (Luke 7:45), but Paul infuses it with a deeper spiritual meaning: it is an expression of Christian love and an outward sign of their shared faith.
“What is a holy kiss? It is one that is not hypocritical, like the kiss of Judas. The kiss is given in order to stimulate love and instill the right attitude in us toward each other. When we return after an absence, we kiss each other, for our souls hasten to bond together. But there is something else which might be said about this. We are the temple of Christ, and when we kiss each other we are kissing the porch and entrance of the temple.” [Saint John Chrysostom (392 AD), Homilies on the Second Epistle to the Corinthians 30,2]
All the holy ones greet you.
In Paul’s letters, hágioi (“saints”, “holy ones”, “those set apart”) refers to ordinary baptized Christians, not just exceptionally holy individuals in the later canonized sense of “saint.” Paul regularly addresses Christian communities themselves as “the holy ones” because they have been consecrated to God through Christ and baptism.
Here, Paul is most likely referring to the Christians who are physically with him as he writes the letter, believers in Macedonia. This is much like someone ending a letter with “everyone here sends their love.”
However, in doing this, Paul is reminding the Corinthians that they are part of a much broader community of believers, reinforcing their identity as belonging to God, and reminding them to live in a manner that is consistent with their sanctified status.
The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with all of you.
Among all of Paul’s letters, this final blessing of 2 Corinthians stands out as the most profound and enlightening. Its trinitarian nature is evident.
You might find it quite familiar, as it is commonly used as the greeting at the beginning of Mass, setting a tone of unity and divine presence.
Saint Thomas Aquinas points out that this benediction refers to all necessary supernatural graces:
“The grace of Christ, by which we are justified and saved; the love of God the Father, by which we are united to him; and the fellowship of the Holy Spirit, who distributes the divine gifts to us” (Commentary on 2 Corinthians)
This blessing encapsulates the essence of God’s blessings and serves as a heartfelt expression of hope and spiritual connection, making it the perfect conclusion to the letter.
Gospel – John 3:16-18
God so loved the world that he gave his only Son,
so that everyone who believes in him might not perish
but might have eternal life.
For God did not send his Son into the world to condemn the world,
but that the world might be saved through him.
Whoever believes in him will not be condemned,
but whoever does not believe has already been condemned,
because he has not believed in the name of the only Son of God.
Our gospel reading for today is the famous excerpt from John Chapter 3. It encapsulates the central message of God’s love and salvation, and reveals the Trinity in action within the divine plan of redemption.
God so loved the world that he gave his only Son,
These words from Jesus are part of his conversation with Nicodemus (John 3:1-21), a Pharisee and a member of the Jewish ruling council who came to Jesus seeking to understand his teachings.
He is describing the profound scope of divine love. It holds nothing back, not even God’s own Son, who is given for the world’s redemption.
Notice that this divine love is not only unfathomably deep but universal: God so loved the world. It is not limited to a single nation, righteous individuals, or only those who reciprocate his love.
so that everyone who believes in him might not perish but might have eternal life.
Faith in the Son who was sent is the path to eternal life.
This offer is extended to everyone by God, who wills salvation for all; however, not everyone is willing to accept this gift.
For God did not send his Son into the world to condemn the world, but that the world might be saved through him.
The world, originally created as good, became entangled in sin and often stands in opposition to God. The purpose of God sending his Son into this sinful world was not to condemn humanity but to offer the salvation it so desperately needs.
The verb for “send” is apostéllō, indicating that the Son had a sacred, all-encompassing mission to fulfill.
Whoever believes in him will not be condemned, but whoever does not believe has already been condemned,
God’s intention is to rescue and redeem rather than to pass judgment. God does not condemn, but some condemn themselves by refusing to embrace his gracious and merciful plan for humanity’s salvation.
because he has not believed in the name of the only Son of God.
In the Jewish culture, one’s name shares the full identity of its bearer. Rejecting the name of Christ rejects all it entails, including God’s profound offer of salvation.
Jesus requires our faith in him as the first step in sharing in God’s divine love. This faith lifts us out of darkness, brings us into the light, and puts us on the path to salvation.
Connections and Themes
The Most Holy Trinity. The mystery of the Holy Trinity is not a theological puzzle to be solved, but the revelation of who God truly is. The Father, the Son, and the Holy Spirit exist in perfect unity, love, and communion. God is not solitary. From all eternity, God is relationship.
This divine reality is revealed throughout today’s readings. When God passes before Moses in our first reading, he does not describe himself in abstract philosophical terms, but as “a merciful and gracious God, slow to anger and rich in kindness and fidelity.” The living God reveals his very nature through love, mercy, patience, and faithfulness.
In our second reading, Paul speaks of “the grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit.” The Trinity is not distant from us. We encounter the Father’s love, the Son’s grace, and the Spirit’s communion in the life of the Church and in our own lives of faith.
Finally, in the gospel reading, we hear perhaps the clearest expression of God’s self-giving love: “For God so loved the world that he gave his only Son.” The Trinity is revealed not through explanation alone, but through salvation. The Father sends the Son into the world, and through the Spirit we are drawn into the very life of God.
The mystery of the Trinity will always exceed our understanding. Christianity is not founded upon fully comprehending God, but upon trusting him, worshipping him, and entering into relationship with him. Every time we make the Sign of the Cross, we proclaim not only what God is, but who God is: Father, Son, and Holy Spirit — a communion of perfect love into which we ourselves are invited.
Today’s solemnity calls us not merely to study the Trinity, but to live in the presence of the Triune God with humility, gratitude, and wonder.
