There is no scholarly consensus over what precisely constitutes a religion. It may be defined as a cultural system of designated behaviors and practices, world views, texts, sanctified places, prophesies, ethics, or organizations, that claims to relate humanity to supernatural, transcendental, or spiritual elements.
There are as many gods as there are ideals. And further, the relation of the true artist and the true human being to his ideals is absolutely religious. The man for whom this inner divine service is the end and occupation of all his life is a priest, and this is how everyone can and should become a priest.
Friedrich Schlegel, Philosophical Fragments, P. Firchow, trans. (1991) § 406.
