This guy was warped beyond belief:
Emulating an earlier Franciscan missionary, Francis Solanus, Serra made a habit of punishing himself physically, to purify his spirit. He wore a sackcloth spiked with bristles, or a coat interwoven with broken pieces of wire, under his gray friar's outer garment.[24] In his austere cell, Serra kept a chain of sharp pointed iron links hanging on the wall beside his bed, to whip himself at night when sinful thoughts ran through his mind. His nightly self-flagellations at the college of San Fernando caught the ears of some of his fellow friars. In his letters to his Franciscan companions, Serra often referred to himself as a "sinner" and a "most unworthy priest."
In one of his sermons in Mexico City, while exhorting his listeners to repent their sins, Serra took out his chain, bared his shoulders and started whipping himself. Many parishioners, roused by the spectacle, began sobbing. Finally, a man climbed to the pulpit, took the chain from Serra's hand and began whipping himself, declaring: "I am the sinner who is ungrateful to God who ought to do penance for my many sins, and not the padre [Serra], who is a saint." The man kept whipping himself until he collapsed. After receiving the last sacraments, he later died from the ordeal.[25]
During other sermons on the theme of repentance, Serra would hoist a large stone in one hand and, while clutching a crucifix in the other, smash the stone against his chest. Many of his listeners feared that he would strike himself dead. Later, Serra suffered chest pains and shortness of breath; Palóu suggests that Serra's self-inflicted bruises were the cause. While preaching of hell and damnation, Serra would sear his flesh with a four-pronged candle flame — emulating a famed Franciscan preacher, John of Capistrano.[26] Palóu described this as "quite violent, painful, and dangerous towards wounding his chest."[27]
Serra did not stand alone among Catholic missionaries in displaying self-punishment at the pulpit. The more zealous Franciscan and Jesuit missionaries did likewise. But few took it to the extremes that Serra did. The regulations of the college of San Fernando said that self-punishment should never be carried to the point of permanently incapacitating oneself.[28] Some of Serra's colleagues admonished him for going too far.
