Theocentricism is the belief that God is the central aspect to our existence, as opposed to, for instance, anthropocentrism (centers upon man) or existentialism (centers upon the experience of existence).
In modern theology, it is often linked with stewardship and environmental ethics. It is the belief that human beings should look after the world as guardians and therefore in the way in which God wants them to. Humans should be considerate to all, from animals to plants to humans themselves. It maintains that human beings are merely here for a short time and should be looking after the world for future generations.
