Teilhard and Whitehead on Hope
2025-03-18 19:30 - 20:30 UTC
Featuring Jay McDaniel, PhD and Ernie Tamminga, PhD
We live in a time of need, where people throughout the world seek visions of hope. This discussion explores the shared vision of Teilhard de Chardin and Alfred North Whitehead, both of whom see the universe as an evolutionary process with inwardness or subjectivity present from the very beginning. Teilhard emphasizes a cosmic pull toward the Omega Point, where love becomes all-encompassing, and describes the emergence of the noosphere—a sphere of collective human thought and consciousness—as a critical phase in this evolution. Whitehead, similarly, envisions a divine lure guiding all actual entities toward richer experiences and individuation, suggesting that love and creativity are not incidental to the cosmos but intrinsic to its unfolding. Tamminga and McDaniel will explore ways in which the two perspectives can be combined to form a meaningful, scientifically informed, and spiritually rich vision for human beings at this critical stage in history.

Green Saints for a Green Generation
2025-05-06 19:30 - 20:30
Featuring Libby Osgood, CND, PhD with Celia Ashton, Amirah Orozco, and Flora x. Tang
Join us for an online conversation featuring the editor and three chapter authors of “Green Saints for a Green Generation,” a book written by young Catholic women (scientists, sisters, theologians) on “saints”—canonized and not—who connect their faith to concern for our common home. The writers lift traditional saints and contemporary figures (such as Clare of Assisi, Ignatius of Loyola, Marguerite Bourgeoys, Thomas Merton, Toni Morrison, and the Martyrs of the Amazon) who provide needed inspiration and hope for our ecological journeys and encourage all of us (young and old) to become green saints. By connecting these key figures to environmental responsibility, the contributors encourage the not-yet informed to become active, inviting younger generations to join the ecological movement, to take on the responsibility from their elders, and to shoulder the ecological burden for themselves.

Growing in the Radiance of Teilhard the Mystic: A Two-Part Virtual Series
Evenings with Kathy Duffy, SSJ
Wednesday, February 4 and 11
6:00 pm – 8:00 pm EST
One of the most important capacities for those of us who wish to live a truly mystical life is the ability to see. Openness to the other and to the many sensations in our immediate surroundings deepens our ability to access the radiance of Matter’s inner face, as well as our capacity to respond to the Divine Presence we encounter within. As we engage passages from Teilhard’s mystical writings, we come to know the Cosmic Christ as the source of all Radiance, drawing the human family toward the light and stirring up passionate desire to join in the work of creation.
Kathleen Duffy, SSJ directs the Institute for Religion and Science. She is President of the American Teilhard Association, former editor of Teilhard Studies, and serves on the Advisory Board of Cosmos and Creation. She has published Teilhard’s Mysticism: Seeing the Inner Face of the Evolution; Teilhard’s Struggle: Embracing the Work of Evolution; and edited the volume of essays, Rediscovering Teilhard’s Fire.
Donation – Suggested Scale $35-$40 for both evenings, February 4 and 11.

Explicitly Embodied: Exploring the Sacred Synergy of Spirit and Psyche presents an integrative perspective of spiritual growth as an expression of conscious evolution. Drawing on the insight that spiritual awakening is a process of embodiment, this talk proposes that psyche and spirit mature together through lived, relational, and incarnational experience.
At the heart of this webinar is Sacred Synergy, Andrew Del Rossi’s forthcoming book with Paulist Press. The text presents a framework that brings psychology and spirituality into a dynamic and relational dialogue. Engaging the evolutionary mysticism of Pierre Teilhard de Chardin, the depth psychology of Carl Jung, and the integrative vision of psychosynthesis articulated by Roberto Assagioli, the talk demonstrates how inner transformation calls us to participate in a larger cosmological and evolutionary process. Rather than remaining at the level of abstraction or esoteric speculation, these perspectives are translated into accessible, real-world applications that address everyday challenges of meaning, identity, and wholeness.
Designed for both seasoned seekers and those new to exploring the spiritual life, this webinar emphasizes concrete practices, examples, and interpretive tools that nurture authenticity, joy, and purpose amid the complexities of contemporary life. By affirming embodiment as the locus of spiritual realization, Explicitly Embodied invites participants to experience spiritual growth as conscious participation in the sacred unfolding of the universe.
