Religion has supplied the justification for centuries of war and persecution

The argument

Critics of religion point to the historical record of violence carried out in its name. Wars have been fought over doctrine, religious minorities have been expelled, forcibly converted and killed, heretics have been tried and executed, and conquest has been blessed by clergy and presented as a sacred duty. Critics argue that this is not an incidental association: the violence was justified by religious claims, organised through religious institutions, and understood by its perpetrators as obedience rather than crime. The argument is that religion contributes something distinctive to conflict rather than merely accompanying it. Ordinary disputes over land or power can be settled by compromise, because both sides can calculate costs. A dispute framed as the will of God is harder to settle: the terms are not negotiable, concession is apostasy, and an opponent who is not merely a rival but an enemy of truth may be treated accordingly. Critics argue that the conviction of acting on divine authority is what converts disagreement into a licence for cruelty, and what allows the cruel to feel righteous. Critics add that religion's capacity to confer legitimacy has been available to any power willing to claim it, and has repeatedly been used to sanctify slavery, conquest and the subjection of women as part of a divine order rather than a human arrangement open to challenge. The harm, on this view, lies not only in the violence but in the authority that made it unquestionable. Because religion has supplied the justification, the organisation and the moral cover for persecution and war across centuries, this argument concludes, it has been a force for evil.

Premises

Counter-arguments

Defenders of religion reply that the violence cited was driven by the ordinary motives of power, land and ethnicity, with religion supplying the vocabulary rather than the cause, and that the twentieth century's largest atrocities were committed by explicitly irreligious regimes. They add that the same traditions produced the abolitionists, the hospitals and the shelter of the persecuted, so a factor present in both the cruelty and the charity cannot be what distinguishes them.

Rejecting the premises

[Rejecting P1] That these conflicts were justified in religious terms and organised through religious institutions does not establish religion as their cause, since the same institutions held land, revenue and political power, and conflicts over those are conducted in whatever idiom confers legitimacy. [Rejecting P2] The claim that divine framing resists compromise is plausible but is offered without the comparison that would support it, and conflicts framed around nation, race or ideology have proved at least as resistant to settlement. [Rejecting C] The conclusion is comparative - more harm than good - and no premise weighs anything against the harms. The charitable, educational and consolatory record cited by the opposing positions is never addressed, so the premises can at most establish that religion has done grave harm.
