Be careful, warned Nietzsche, lest in fighting the dragon you become the dragon. I see the confusion of politics and religion as one of the greatest barriers to grace. C. S. Lewis once said that almost all crimes of Christian history have come about when religion is confused with politics. Politics, which always runs by the rules of ungrace, allures us to trade away grace for power, a temptation the church has often been unable to resist.
Nietzsche warned that in the struggle with evil or challenges, there is a danger of becoming the very thing one opposes, symbolized as becoming the dragon. This caution highlights how easy it is to lose one's moral integrity when engaged in conflict, especially if one is not careful of one’s inner virtues.
C. S. Lewis pointed out that many of Christianity's historical wrongdoings stem from the confusion of religion with politics. Politics often operates without grace and seeks power, leading the church to compromise its principles, a temptation that has repeatedly hindered its spiritual mission.
