Sacred Synergy: Spiritual & Psychological Growth in an Evolving World
2026
Available via Paulist Press

Sacred Synergy presents a unique and comprehensible integration of spirituality and science through the integration of psychology and spirituality using the insights of Teilhard de Chardin, Carl Jung, and Roberto Assagioli.

“By weaving the psychological frameworks of Carl Jung and Roberto Assagioli with the evolutionary spiritual vision of Teilhard de Chardin, Del Rossi’s Sacred Synergy offers seekers and scholars a compelling, integrative pathway toward wholeness—one that honors both the depths of the psyche and the unfolding spiritual horizon of consciousness.”
—Kathleen Duffy, SSJ, president, American Teilhard Association

“For many of us, Teilhard de Chardin’s cosmic vision has been both intellectually insightful and religiously transformative. It begs comparison with the works of other great thinkers and spiritual writers in the age of science. In this stimulating work, Andrew Del Rossi enriches our understanding of both C. G. Jung and Roberto Assagioli by placing their psychological insights inside the expansive hopefulness we find in Teilhard’s thoughts about the universe, humanity, and God. Sacred Synergy exemplifies the nuance that Teilhard was looking for in every creative synthesis.”
—John F Haught, Georgetown University, author of The Cosmic Vision of Teilhard de Chardin

Encountering Teilhard: The Living Legacy of Pierre Teilhard de Chardin
Juan V. Fernandez de la Gala (ed.)
2026
Available via Orbis Books

As the influence of French Jesuit Pierre Teilhard de Chardin continues to expand in the church, the academy, and beyond, Encountering Teilhard offers a fascinating testament to his importance through reflections by many who have studied and been shaped by his unique integration of science and Christian faith. Contributors include Joan Chittister, Ilia Delio, John Haught, Matthew Fox, Kathleen Duffy, Mary Evelyn Tucker, John Grim, Libby Osgood, Leonardo Boff, José Ignacio Gonzalez-Faus, SJ, Antonio Spadaro, SJ, and many more. Their testimonies speak not only of the gratitude so many feel for Teilhard’s prophetic intuitions, but also of how much his thought can still contribute to the Church of the future.

As the editor notes, Teilhard lived during dark times—as a stretcher-bearer in World War I, and later enduring exile and restrictions on his work by the Vatican and his Jesuit order. “Nevertheless, Teilhard knew how to keep his hope unscathed.” In one of his prayers he wrote, “Do not be troubled by the difficulties of life, by its ups and downs or by its disappointments, or because the future seems at times a little bleak. / Want what God wants. Abandon yourself into his hands of providence, and trust blindly in that God who wants you for himself just as you are.”

Convergences: Forty Encounters with Teilhard de Chardin
Juan V. Fernández de la Gala (ed.)
2025
Available via SalTerrae

“Forty people, forty lives touched by Teilhard de Chardin. In this choral book, Juan V. Fernández de la Gala collects testimonies from scientists, theologians, religious leaders, and seekers who found in the “Teilhardian” vision a key to uniting faith and science, body and spirit, evolution and hope. From the Amazon to Rome, passing through laboratories, classrooms, and communities, each encounter is a story of transformation. More than a tribute, it is a map of new paths, where matter becomes sacrament and the universal Christ summons us to cosmic communion. A reading that questions and accompanies.”

Psycho-Spiritual Union: Integrating Spirituality and Psychology in Teilhard, Jung, and Assagioli
2020
Available via the American Teilhard Association

“The fields of spirituality and psychology hold the power to connect individual human persons to the self, to others, and to the world, and thus to wholeness. This paper explores how the thought of Pierre Teilhard de Chardin, Carl Jung, and Roberto Assagioli can advance a spiritual understanding of the human psyche that affirms its connection to the collective consciousness of the noosphere and to the transpersonal. Although the thought of Teilhard, Jung, and Assagioli share many similarities, the most prominent overlap occurs in their consensus that wholeness emerges from relationship.”
