I find the biggest difference with deeper greener styles of Christianity is their post-anthropocentrism. That is, they are not so human centred. Instead of limiting their spiritual focus to the relationship of God to humanity, or even more myopically, of God to the individual, a more expansive awareness is embraced. So not only is the relationship of God to the human considered but so too is the relationship of God to the non-human, and of the human to the non-human. It’s not so one dimensional. It’s much more holistic. And this post-anthropomorphism flows into Christian ritual, experience, storytelling, symbolism, ethics, theology, social organisation, and more. It flows into the life of how we worship, how we pray, and how we read and interpret the gospel. It opens up aspects of the Christian tradition that have been long forgotten and neglected.
Embracing such styles of Christianity does however involve a lot of unlearning. It involves re-examining what we’ve been told are Christian teachings and testing how intrinsic to Christianity they actually are. Is the earth truly to be left behind? Do animals only have utility value? Is the body irrelevant or even inimical to spiritual practice? Is the Spirit of God not to be found flowing in the earth as well as the sky, in the female as well as the male, in the body as well as the mind? Can we not, with the Psalmist, joyously call on sun and moon, mountains and trees to praise God with us, as fellow worshippers? How much of our inherited, human-centred view is intrinsic to Christianity and how much is merely the cultural accretion of the centuries? It can be surprising to learn what the scriptures and more ancient expressions of Christianity and Judaism actually say.
