The Nicaean Creed brings Christians together. It unites them and makes it clear that they believe in a God who is the "giver of life". Anything that prevents and opposes life - of humanity and nature, stands therefore not in the Christian tradition. Nevertheless, Christianity has contributed on a large scale to the increasing exploitation of God's creation and, consequently, to its destruction. This is partly due to an economic starting point that has always placed financial growth at the centre of society since the 19th century. This economic attitude of permanent growth is a fundamental evil for the exploitation and destruction of God's creation and its Human kind, as it is based on injustice and the power of the strongest. Both attitudes do not stem from Christian ethics and are not compatible with it. This economic arrogances of `always wanting more', which is strongly linked to one of the deadly sins, namely greed, is devastating for interpersonal coexistence and the peaceful and social coalescence of a society, as well as for a care for creation. Nature does not need humanity, but humanity needs nature. In this article, after analysing the destructive economic forces of Christian contexts, I will take a closer look at the approach of the degrowth movement, which is strongly characterised by an ethics of enough, in order to make clear what role the World Council of Churches (WCC) has already played here and to what extent such an economy urgently needs to be implemented by a Christian ethical approach.
