The mystery of the Trinity is the beginning and end of all revealed truth. We are baptized in

the name of the Father, the Son and the Holy Spirit and our souls enter into relationship with each of the Three Divine Persons. We are daughters and sons of the Father, brothers, sisters and co-heirs with the Son and sanctified by the Holy Spirit continually to make us resemble Jesus Christ.
But, how can we contemplate something so great as the Holy Trinity when we are such lowly creatures? St. Teresa wrote that she was “amazed at seeing so much majesty in a thing as lowly as my soul;” then Our Lord said to her: “It is not lowly, my daughter, because it is made in my own image.” This should give us the courage to come in prayer before The Most Holy Trinity through Jesus Christ, through whose human face God chose to reveal Himself to us.

Words are not needed, we need only rejoice in the splendor of His Face. Pope Benedict XVI tells us, “To rejoice in the splendor of His Face means penetrating the mystery of His Name made known to us in Jesus, understanding something of His interior life and of His Will, so that we can live according to His plan for humanity. Jesus lets us know the hidden Face of the Father through His human Face; by the gift of the Holy Spirit poured into our hearts.”
We rejoice in the splendor of His Face as we gaze at Him, and while we gaze at Him, He gazes at us: “How beautiful is this gaze of Jesus – How much tenderness is there!” says Pope Francis. Pope Francis urges us to reflect on Jesus gaze upon us: “How is Jesus looking at me?

With a call? With a pardon? With a mission? But on the path He created, all of us are being looked at by Jesus. He always looks at us with love. He asks us something, he forgives us for something and he gives us a mission… May each one of us think: ‘Lord, You are here, among us. Fix your gaze on me and tell me what I must do: how I must repent for my mistakes, my sins; what courage do I need to go forward on the path that You first created.” St. John of the Cross says the gaze of God is active, “for God’s gaze is to love and to work favors. His Gaze is love and love does things. God’s gaze works four blessings in the soul: it cleanses her, makes her beautiful, enriches her and enlightens… making her like Himself.”
By this mutual gaze of love between the Face of God and the soul man, God restores His Image in our souls where, incredibly, He chooses to dwell. In The Spiritual Canticle, St. John of the Cross exclaims “O, then, most beautiful soul who dost so much desire to know the place where your Beloved is in order to seek him and to be united with him, He tells you now that you yourself are the abode wherein He dwells, and the closet and hiding place where He is hidden. It is a matter of great contentment and joy for you to see that all your good and all your hope are so near that you cannot be without them. ‘Behold’ says the Spouse, ‘the kingdom of God is within you’ (Luke 17:21), and his servant the Apostle Paul says: ‘We are the temple of the living God’ (2 Cor 6:16).”

St. Elizabeth of the Trinity on receiving news of the baptism of her niece, wrote to her sister, “I feel full respect, for this little temple of the Blessed Trinity…If I were near her I would kneel down to adore him who dwells within her.”
Prayer to The Holy Trinity by St. Elizabeth of the Trinity
“My God, Blessed Trinity! Draw from my poor being what most contributes to your glory, and do with me what you wish both now and in eternity. May I no longer place between us any voluntary hindrance to your transforming action… Second, by second, with a forever ‘actual’ intention, I desire to offer you all that I am and all that I have. Make my poor life, in intimate union with the Word Incarnate, an unceasing sacrifice of glory to the Blessed Trinity…

My God, how I wish to glorify you! O, if only in exchange for my complete immolation, or for any other condition, it were in my power to enkindle the hearts of all your creatures and the whole of creation in the flames of your love, how I would desire to do so! May at least my poor heart belong to you completely, may I keep nothing for myself not for creatures, not even a single heartbeat. May I have a burning love for all mankind, but only with you, through you and for you… I desire above all to love you with the heart of Saint Joseph, with the Immaculate Heart of Mary, and with the adorable Heart of Jesus; and, finally, to submerge myself in that infinite ocean, that abyss of fire that consumes the Father and the Son and the Holy Spirit for ever and ever.
O Jesus, who said: ‘No one knows the Son except the Father, and no one knows the Father except the Son and any one whom the Son chooses to reveal him’ (Matt 11:27) ‘Show us the Father, and we will be satisfied!” (John 14:8)
And you, O Spirit of Love! ‘Teach us all things’ (John 14:26) and ‘form Jesus with Mary in us’ (Gal 4:19) until we ‘become perfectly one; (John 17:23) in ‘the bosom of the Father’ (John 1:18). Amen.
