Pierre Teilhard de Chardin's spiritual masterpiece, "The Divine Milieu", in a newly revised translation by Sion Cowell, is addressed to those who have lost faith in conventional religion but who still have a sense of the divine at the heart of the cosmos. 'The heavens declare the glory of God', sings the Psalmist. Teilhard would agree. 'We are surrounded', he says, 'by a certain sort of pessimist who tells us continually that our world is foundering in atheism. But should we not say rather that what it is suffering from is unsatisfied theism'. He sees a universe in movement where progress is the spiritualisation of matter and its opposite is the materialisation of spirit. Teilhard opts for progress. "The Divine Milieu" is the divine centre and the divine circle, the divine heart and the divine sphere. "The Divine Milieu" is written for those who listen primarily to the voices of the Earth: its purpose is to provide a link to traditional Christianity (as expressed in Baptism, Cross and Eucharist) in order to demonstrate that the fears prevalent in contemporary world society as it abuses its very foundation - Mother Earth - may be better understood by the Gospel path.Teilhard's primary purpose is to show a way forward, which he sees as the 'Christian religious ideal'.
