On Trinity Sunday, reflect on spiritual fidelity to the Father, Son, and Holy Spirit, and the call to deeper union with God through the Virgin Mary.
Newsroom, June 15, 2025, Gaudium Press – Recognizing the insufficiency of human intelligence before the greatest mysteries of our Faith, all that remains is to offer a tribute of love and fidelity to the Father, the Son, and the Holy Spirit.
Fidelity to the Indivisible Trinity
On this Solemnity of the Most Holy Trinity, Our Lord Jesus Christ says to His disciples: “I still have many things to say to you, but you cannot bear them now” (Jn 16:12).
“Whoever listens to you listens to me; whoever rejects you rejects me; and whoever rejects me rejects the One who sent me” (Lk 10:16).
For three years, the apostles lived with Our Lord Jesus Christ, hearing His teachings and witnessing clear manifestations of His divinity: multiplying loaves in the desert, calming the sea in a storm, or raising a man from the dead.
However, the moment had come for the Savior to return to the Father, and then send the Paraclete Spirit, who would lead them into all truth (cf. Jn 16:13).
When He announced His Ascension, the apostles were saddened. Why? Because they held a materialistic conception of God and felt abandoned by the loss of His physical presence. A new “phase” was beginning—God was inviting them to a deeper relationship, one that required moving beyond human perceptions of the Divine Master. These limited views became obstacles to the new revelations Christ desired to give. Thus He said: “I did not tell you this from the beginning, because I was with you” (Jn 16:4), and you were not yet able to understand. Moreover, the physical absence of the Lord demanded a greater effort from the apostles in discerning and remaining faithful to the inspirations of the Holy Spirit.
The same happens in our own spiritual journey. In the beginning, God grants us sensible experiences to help fix our souls on the path of virtue. Later, He calls us to a higher relationship, entirely supernatural, requiring constant purification from our vices. How many words, thoughts, and actions can render us unworthy to host the Three Divine Persons within us!
Let us not deceive ourselves with a “semi-fidelity.” Whoever rejects the Son also rejects the Father. If we refuse to take the steps Jesus asks of us, we also lose the gifts of the Holy Spirit, for “the Spirit of truth… will take from what is mine and declare it to you,” and “everything that the Father has is mine” (Jn 16:13–15).
Fidelity to One God
There have been saints, like Saint Catherine of Siena, who could discern the action of each Person of the Trinity within their soul. We too must strive to remain attentive to the inspirations God communicates to us interiorly. Often, our own disordered tendencies block the action of the Holy Spirit and make us deaf to His voice.
In his letter to the Romans, Saint Paul teaches that we are justified before God through the love that the Paraclete pours into us (cf. Rom 5:1, 5).
Undoubtedly, the most secure way to make ourselves worthy of this justification is to entrust ourselves without reserve to the Blessed Virgin Mary—Daughter of the Eternal Father, Mother of the Incarnate Word, and Spouse of the Holy Spirit. She is the unmatched model of submission and fidelity to the divine will.
Blessed, then, are those whom the Lord finds watchful, with souls open to hearing His inspirations. To these, God will grant a share in His divine wisdom.
Thus, today’s liturgy invites us to deepen our faith so that, in this celebration of the Most Holy Trinity, we may grow in fidelity to the Father, the Son, and the Holy Spirit—alongside Our Lady—toward eternal beatitude.
