In a sacramental ecology, divine grace is to be found in the evolutionary emergence of life. The ‘Epic of Evolution’ is the scientific story that reveals that we live in an approximately 14 billion year old universe on a planet that is approximately 4.6 billion years old and that we are a part of the ongoing process of life that has existed on Earth for roughly 4 billion years. Nature's Sacrament focuses on the religious and ecological significance of the evolutionary epic in an effort to seamlessly connect the ecological value attributed as a part of an understanding of the evolutionary connectedness of life on Earth, with the Divine grace understood to be present in Christian sacramental worship. David C.

The increasing awareness of environmental issues as ultimately moral issues has led to the intersection of religion and environment. Sacramental Commons presents a unique way of looking at this topic by relating the Christian word 'sacrament' (signs of divine presence) to the term 'commons' (shared place and shared goods, among people and between people and the natural world), suggesting that local natural settings and local communities can be a source for respect and compassion. Sacramental Commons uses Earth-oriented biblical teachings, and ideas from such thinkers as Hildegard, St. Francis, John Muir, and Black Elk, to provide insights about divine immanence in creation, human commitments to creation, and human accountability to the Spirit, Earth, and biotic community. It extends the concept of 'natural rights' beyond humans to include all nature, and affirms intrinsic value in ecosystems in whole and in part. Sacramental Commons declares that the Earth commons and its goods should be shared equitably by human communities and individuals living in interdependent relationships with other members of the community of life. It suggests essential values that will stimulate care for the commons, and embodies them in principles of an innovative Christian Ecological Ethics.

John Chryssavgis explores the sacred dimension of the natural environment, and the significance of creation in the rich theological history and spiritual classics of the Orthodox Church, through the lens of its unique ascetical, liturgical and mystical experience. The global ecological crisis affecting humanity's air, water, and land, as well as the planet's flora and fauna, has resulted in manifest fissures on the image of God in creation. Chryssavgis examines, from an Orthodox Christian perspective, the possibility of restoring that shattered image through the sacramental lenses of cosmic transfiguration, cosmic interconnection, and cosmic reconciliation. The viewpoints of early theologians and contemporary thinkers are extensively explored from a theological and spiritual perspective, including countering those who deny that God's creation is in crisis. Presenting a worldview advanced and championed by the Orthodox Church in the modern world, this book encourages personal and societal transformation in making ethical and economic choices that respect creation as sacrament.
