The Mission is a 1986 British drama film about the experiences of a Jesuit missionary in 18th century South America (more from Wikipedia).
This film provides an ironic and intensely dramatic demonstration of how organized religion – even when motivated by truth and compassion – traps and harms its adherents. Selfless missionaries manage to convert a hostile and warring South American tribe into peace-loving, industrious, and humble workers, only to doom the latter to destruction by binding them to the mission instead of freeing them to escape approaching national powers.
Whether it’s the converted Mendoza who leads the tribesmen with the sword or the pacifist Father Gabriel who leads them to slaughter, the tribesmen are defeated and destroyed. Neither violence nor non-violence will save those who are in the grip of organized religion.
Organized religion is a system, a way of thinking that affects and infects not only the globally-powerful Roman Catholic Church but also the small out-of-the-way mission in South America. It is the pathology that results when we are not content to let God led and manage His own kingdom.
Let us proclaim the truth of Jesus Christ while forsaking any attempt to organize those who would believe in Him.
