Saint Mary, source of light and life

“I have come into the world as light, so that everyone who believes in me shall not remain in darkness.” (John 12:46)

I. The Pentecost Address: Light Illuminating History

Peter’s address on the day of Pentecost, recorded in the Acts of the Apostles, is the first public proclamation of the Gospel following the outpouring of the Holy Spirit. Having denied his Lord three times just days before, Peter now stands before the crowd gathered in Jerusalem and proclaims with a clarity and audacity only the Spirit can explain: “Therefore let all the house of Israel know for certain that God has made him Lord and Christ this Jesus whom you crucified” (Acts 2:36). The proclamation is direct, without qualifications: those who heard are responsible for the crucifixion of the Messiah, and the response demanded is conversion and baptism for forgiveness of sins and the gift of the Spirit (Acts 2:38).

The woman who gave birth to the Light of the world is present at this foundational moment of the Church, gathered in the Cenacle with the disciples (cf. Acts 1:14). The light that John proclaimed in his Gospel prologue, “the true light that illuminates every man” (John 1:9), continues to shine now through apostolic preaching and the outpouring of the Spirit. Mary is the human source of this light: she who first received the Word of God in her womb, she who was first illuminated by grace that needed to take on human form, she who accompanied the Light throughout her earthly life and now awaits, in prayer, the same Light’s descent upon all peoples.

II. “I am the light of the world”: The Johannine Revelation

The twelfth chapter of John occurs at a pivotal moment in Jesus’ ministry: Greeks eager to see him signal the arrival of the hour when the “wheat must fall to the ground and die to bear much fruit” (John 12:24). In this context of impending Paschal events, Jesus proclaims the Gospel for this Mass: “I have come into the world as light, so that everyone who believes in me shall not remain in darkness” (John 12:46). Jesus’ self-revelation as light of the world is not a metaphorical statement about his wisdom or teaching; it is an ontological affirmation about his person, who participated eternally in divine light before manifesting himself in flesh.

The faith Jesus demands is belief in himself as Light: not merely intellectual assent to a teaching but an existential conversion that alters one’s life direction, abandoning darkness for the light that illuminates, liberates, and transforms. “Whoever sees me sees him who sent me” (John 12:45): to see Jesus is to see God, because the Light he is is the Light of God manifested in flesh. And Mary, who saw him with her physical eyes from his first moments, is the first to have beheld God’s Light in her Son’s face.

III. Mary, the dawn that precedes the light

The Christian spiritual tradition often uses the image of dawn to refer to Mary in her relationship with Christ: she is the dawn that precedes the Sun, announcing His coming, dividing night from day. The image is biblical: in Song of Songs, the bride is described as “beautiful as the moon, radiant as the sun, awesome as an army with banners” (Ct 6:10). Mary is the most luminous creature in history, not by her own light but by the radiance of the Light that dwelt within her. She who for nine months was the “temple” where the Son of Light grew, she who illuminated Him with her maternal milk and the warmth of her arms, she who received from Him, refracted through her perfect humanity, the divine clarity that transfigured her from within.When Peter announces on Pentecost that God has made Lord and Christ this Jesus, he proclaims what Mary knew since the Annunciation: that the Son she conceived was the Lord of all history. The difference is that Mary knew without yet being able to publicly proclaim it, keeping in her heart what time had not yet allowed her to reveal. On Pentecost, the light that Mary had privately held for decades burst forth publicly over the entire world: the Spirit who covered her with His shadow in Nazareth now covers all humanity with His grace.

IV. Mary, Source of Light that illuminates the Church

The sixteenth Mass of the Collects contemplates Mary as Source of Light and Life, a title recognized by Mariology as one of the most beautiful and precise attributes bestowed upon the Mother of God by Christian piety. “Source of light” because from her was born what John proclaims as “the true light” (Jn 1:9). “Source of life” because from her was born He whom John designates as he who came so that those who believe in Him “have life, and have it abundantly” (Jn 10:10). The double designation is not redundant: to illuminate and to vivify are the two fundamental actions of the Spirit of God, and Mary, filled with the Spirit who covered her with His shadow, participates in his illuminating and vivifying function.The Church celebrating this Mass during Paschal Time is invited to renew its consciousness of origin: we are children of light that Mary brought into the world, we are vivified by the life she received in human form, we are baptized into the same Light that Peter proclaimed on Pentecost. And Mary, who was present at the Cenacle when the Spirit descended, continues to be a source of light and life for the Church of all times, because she continues to intercede for the gift of the same Spirit she received in the most full and perfect form that a human creature can receive.
