March 9, 2026, Adrian, Michigan – Radiance, the ability to see beneath the surface of matter to its heart, is the hallmark of a true contemplative. During an in-person retreat, Growing in Radiance with Teilhard de Chardin, Sister Kathleen Duffy, SSJ, draws on some of the beautiful, mystical essays of the Jesuit paleontologist to explore the inner glow that Teilhard experienced in his encounters with Christ in matter.

The retreat begins at 6:30 p.m. Sunday, April 26, 2026, at Weber Retreat and Conference Center and concludes at 3:30 p.m. Wednesday, April 29, 2026. 

Sister Kathleen, Professor Emerita of Physics and Director of the Institute for Religion and Science at Chestnut Hill College, is President of the American Teilhard Association. Her research focuses on the religious essays of Pierre Teilhard de Chardin and the relationship of his synthesis to modern developments in science.
