James Frazer, The Golden Bough — Chapter 57:… (1922)
“ If we ask why a dying god should be chosen to take upon himself and carry away the sins and sorrows of the people, it may be suggested that in the practice of using the divinity as a scapegoat we have a combination of two customs which were at one time distinct and independent. On the one hand we have seen that it has been customary to kill the human or animal god in order to save his divine life from being weakened by the inroads of age. On the other hand we have seen that it has been customary to have a general expulsion of evils and sins once a year. ”
