On Conversion

Bernard of Clairvaux delivered this sermon to address the spiritual complacency he observed among the secular clergy of his day. Writing in 1140 during his mature period as Abbot of Clairvaux, Bernard confronted priests and clerics who had grown comfortable in their positions while neglecting the radical demands of Christian conversion. The work emerged from his broader reformist concerns about clerical corruption and spiritual lukewarmness that threatened the Church's witness.

Bernard argues that conversion is not a single moment of decision but an ongoing transformation that must characterize every Christian life, especially those in clerical office. He distinguishes between mere moral improvement and true conversion, insisting that genuine conversion involves a complete reorientation of the heart toward God. The sermon traces how pride, the root of all sin, manifests particularly in clerical life through love of honor, pursuit of temporal gain, and spiritual presumption. Bernard demonstrates how these vices corrupt not only individual souls but undermine the pastoral office itself. He calls for a return to authentic conversion marked by humility, self-knowledge, and genuine love of God rather than love of self.

This sermon has endured because it addresses perennial temptations that face religious leaders across centuries. Bernard's psychological insight into how spiritual authority can become spiritually corrupting remains penetrating, and his call for ongoing conversion rather than static religious observance speaks to contemporary struggles with nominal Christianity. The work's influence extends beyond medieval monasticism to inform later Protestant critiques of clerical privilege and modern discussions of pastoral integrity.

Who should read this: Pastors, priests, and religious leaders wrestling with the spiritual dangers of their calling will find Bernard's diagnosis uncomfortably accurate and his remedy compelling. Those interested in medieval spiritual theology and the history of clerical reform will appreciate its historical significance, though readers seeking devotional comfort rather than challenging examination should look elsewhere.
