The Workshop "Spirituality and Astronomy," organized by the Vatican Observatory, concluded on Sunday, August 30, at its headquarters in Castel Gandolfo. The initiative, born from the idea of bringing scientific observation of the universe into dialogue with spiritual experience, was organized by Sr. Irene Tranquillini, OFMI, Fr. Matteo Galaverni, Fr. Gabriele Gionti, SJ, and Fr. Robert Janusz, SJ. The aim was to build a path capable of weaving together scientific rigor, theological reflection, and contemplative experience, without sacrificing any of the three dimensions to the others. From Friday, August 28 to Sunday, August 30, twenty participants from a surprisingly varied background — doctoral candidates and university students, professors, priests, religious sisters, lay professionals, pastoral workers, and teachers — gathered at the Vatican Observatory, united by the desire to reflect together on the meaning of the cosmos.
The proceedings were opened by Father Richard D'Souza, Director of the Vatican Observatory, who traced the centuries-long history of the Papal Observatory before turning to some of the most advanced frontiers of contemporary astronomy. The participants then moved to the pontifical parish of Castel Gandolfo for Holy Mass. On the liturgical memorial of Saint Augustine, Fr. Paul Gabor, SJ, highlighted how the great Doctor of the Church originated the metaphor of Nature as a Book.
The first day concluded with a visit to the museum and historic telescopes of the Observatory, at the Papal Palace and the Barberini Domes, and with sky observation through the 1891 Carte du Ciel telescope (for more information and to visit the Observatory: https://www.vaticanobservatory.va/en/visit).
The second day opened with a talk by Monsignor Tomasz Trafny, of the General Secretariat of the Synod, who offered an anthropological reading of the encounter between science, spirituality, and religiosity, identifying wonder as the deep driving force that pushes human beings toward both scientific inquiry and religious questioning.
Sister Irene Tranquillini picked up this same thread, showing how astronomical observation and contemplation of the cosmos generate precisely the kind of wonder capable of awakening both the critical sense of science and humanity's religious openness.
Along the same lines, Father Robert Janusz led participants in a reflection on theological integration, showing how love-charity unfolds harmoniously across the different dimensions of the person: soul, reason, and body.
On the more strictly scientific side, Fr. Matteo Galaverni guided participants through the evolution of the cosmos: from the Big Bang to the cosmic microwave background, up to current cosmological models, without neglecting the still-open enigmas of dark matter and dark energy that continue to challenge the international scientific community.
Father Gabriele Gionti then introduced the spiritual journey of Monsignor Georges Lemaître, the Belgian priest considered the father of the Big Bang theory. Tracing his spiritual formation and scientific path, from his correction of Einstein's relativistic cosmological models to his development of the theory of the expansion of the universe, Fr. Gionti recalled how Lemaître arrived theoretically at the law of galactic recession before Edwin Hubble confirmed it observationally, and how he demonstrated the instability of the static cosmological models proposed by Einstein. He also dwelt on Lemaître's well-known criticism of concordism, and on his conviction that science and faith should be considered as two distinct and parallel planes, each with its own method and autonomy, yet capable of mutually enriching one another without becoming confused.
The afternoon concluded with Holy Mass presided over by Fr. Jaceck Olczyk, SJ. In the evening, participants gathered for telescope observations — the Moon, Saturn, Neptune, the Andromeda galaxy, and other celestial objects — and for a prayer vigil led by Fr. Guidalberto Bormolini, who drew on texts and prayers written by great scientists, from Kepler to Marconi.
Sunday morning opened with a talk by Fr. Bormolini, who presented reflections by the Church Fathers on the cosmos and the origin of the world. He used the image of the harmony of the universe's laws which, metaphorically, produces a harmonious sound — hence the suggestive idea of pairing the term "Big Song" with "Big Bang": everything, in other words, would arise not from a simple event, but from an original harmony.
Finally, Fr. Massimo Vedova, OFM Conv., guided participants through the cosmological visions of several great mystical figures, from Hildegard of Bingen to Angela of Foligno, to Simone Weil, emphasizing how the separation imposed by contemporary hyper-specialization between the spiritual, scientific, and mystical dimensions risks generating only dissonance and poor integration in the consciousness of men and women today.
He also observed how many contemporary scientists tend to deny the need to cultivate the mystical-spiritual dimension, and how this stems, in part, from a genuine fear of confronting such questions — a fear fueled also by modern scientism, which reduces every legitimate form of knowledge to the scientific-experimental method alone. Every person, he recalled, is constantly confronted by a question that concerns God, the cosmos, science, and the spiritual dimension of things all at once.
One of the participants shared these words: she said the three days spent together at the Observatory were the kind of gathering that ignites her and makes her feel at home and loved by God.
Many participants testified that they felt welcomed with great warmth and were introduced to horizons of knowledge and spiritual and scientific inquiry they had never imagined exploring — an unexpected enrichment capable of leaving a lasting mark.
The workshop was also an opportunity to lay the groundwork for a future interdisciplinary study program. The speakers shared their intention to analyze texts in which scientists discuss science and religion using the same hermeneutical tools used to study mystical texts, in the belief that this approach could open new and fruitful paths for dialogue between science and faith.
The closing Holy Mass, presided over by Fr. Bayu Christoforus Risanto, SJ, sealed these intense days of study, sky observation, and prayer, confirming the deepest calling of the Vatican Observatory: to be a place where the intelligence that scans the stars and the heart that seeks God can walk together, without becoming confused with one another.
