"Christianity has an admirable example of the natural union between faith and freedom in Dante Alighieri. Precisely his undoubted adherence to Catholic truth allows and illuminates his perfect autonomy of judgement, free from any fear or human conditioning. Dante is not afraid to criticize the work of the popes and their operational choices, to the point of placing several of them in the depths of hell. But in him "the reverence of the supreme keys" never diminishes and never diminishes in the slightest (Inf. XIX, 101). When it comes to expressing reservations or criticisms that he considers due, there are no discounts neither for lay people, nor for ecclesiastics, nor for monarchs, nor for ordinary citizens... all of whom are required, without exception, to abide by the law evangelical."
