Teilhard’s Mass On The World: 100 Years and Moving Forward

This October, the American Teilhard Association, in collaboration with the Neveux du Pere Teilhard de Chardin (The Nephews of Teilhard de Chardin) and the Amis de Pierre Teilhard de Chardin (The Friends of Teilhard de Chardin), gathered to celebrate the 100-year anniversary of Pierre Teilhard de Chardin’s Mass on the World, his prayerful consecration of the cosmos. The weeklong celebration happened at two major venues: Manhattan and Hyde Park, New York.

The American Teilhard Association, since its foundation in 1967, is committed to making the thought and vision of Teilhard more widely available. The Association seeks to bring an encompassing perspective to this great task of shaping the well-being of the Earth community at a time when so many disintegrating forces are at work. Teilhard’s vision of the sequential evolution of the universe provides a firm and inspiring basis upon which to envision a sustainable future. This vision flows through his unified narrative of the evolutionary sequence of the emerging universe – the galaxies, the solar system, the Earth with its living forms, human history, and humanity’s place in the evolving cosmos. This narrative from its origin to the human phenomenon can provide a firm and inspiring basis upon which to proceed. Now, for the first time, humanity is converging towards a new unity in diversity in shaping a multiform planetary civilization. To assist in this work, the Association, since its foundation in 1967, has sponsored annual conferences, lecture series, and a variety of publications. Learn More.

Pierre Teilhard de Chardin was born on May 1st, 1881 to Emmanuel and Berthe-Adele Teilhard de Chardin. While both of his parental lineages were distinguished, it is noteworthy that his mother was the great grandniece of Francois-Marie Arouet, more popularly known as Voltaire. He was the fourth of the couple’s eleven children and was born at the family estate of Sarcenat near the twin cities of Clermont-Ferrand in the ancient province of Auvergne. The long extinct volcanic peaks of Auvergne and the forested preserves of this southern province left an indelible mark on Teilhard.
