Religion, at least the Christian, is the relation of man to himself, or more correctly to his own nature (i.e., his subjective nature); but a relation to it, viewed as a nature apart from his own. The divine being is nothing else than the human being, or, rather, the human nature purified, freed from the limits of the individual man, made objective - i.e., contemplated and revered as another, a distinct being. All the attributes of the divine nature are, therefore, attributes of the human nature.

Ludwig Feuerbach
The Essence of Christianity
