According to Osho, he opposes institutional Christianity as the 'ugliest manifestation' of religion: its tight hierarchy kills living truth, turning spirituality into power politics. By sanctifying violence - crusades, 'holy wars' - it indoctrinates people to commit evil believing it good, and has fueled world wars. Truth, he says, cannot be organized; rigid organization destroys it.
He says the church’s rigid system twists truth and even calls hurting people holy, so real spirituality must stay free and personal.
