Friedrich Nietzsche - On the Genealogy of Morality (Chap. 3.20) lyrics

As history teaches us, the consciousness of being in debt to the gods did not in any way come to an end after the downfall of the organization of the “community” based on blood relationships. Just as humanity inherited the ideas of “good and bad” from the nobility of the tribe (together with its fundamental psychological tendency to set up orders of rank), in the same way people also inherited, as well as the divinities of the tribe and of the extended family, the pressure of as yet unpaid debts and the desire to be relieved of them. (The transition is made with those numerous slave and indentured populations which adapted themselves to the divine cults of their masters, whether through compulsion or through obsequiousness and mimicry; from them this inheritance then overflowed in all directions). The feeling of being indebted to the gods did not stop growing for several thousands of years, always, in fact, in direct proportion to the extent to which the idea of god and the feeling for god grew on earth and were carried to the heights. (The entire history of ethnic fighting, victory, reconciliation, mergers, everything which comes before the final rank ordering of all the elements of a people in every great racial synthesis, is mirrored in the tangled genealogies of its gods, in the sagas of their fights, victories, and reconciliations. The progress towards universal empires is always also the progress toward universal divinities. In addition, despotism, with its overthrow of the independent nobility always builds the way to some variety of monotheism). The arrival of the Christian god, as the greatest [Maximal] god which has yet been reached, thus brought about the maximum feeling of indebtedness on earth. Assuming that we have gradually set out in the reverse direction, we can infer with no small probability that, given the inexorable decline of faith in the Christian god, even now there may already be a considerable decline in the human consciousness of guilt. Indeed, we cannot dismiss the idea that the complete and final victory of atheism could release humanity from this entire feeling of being indebted to its origin, its causa prima [prime cause]. Atheism and a kind of second innocence belong together.—
