How did Christian confession influence autobiographical writing?

Christian confession significantly influenced autobiographical writing by establishing a framework for spiritual self-examination and the revelation of intimate, hidden details of a subject's life. The most influential example of this influence is the Confessions of St. Augustine, written around 400 CE.12

Augustine’s work broke new ground by using the term "confessions" as a catchall for religiously authorized speech, including the praise of God, the blame of self, and the confession of faith. By documenting his personal journey from youthful sinfulness to conversion, Augustine created a model for the "religious autobiography," a genre that focuses on the philosophical and emotional development of the individual soul.234

This tradition of introspective, soul-searching narrative provided a foundation for later autobiographical literature. The influence of this confessional mode persists in modern writing, where it is often associated with the disclosure of painful or intensely personal feelings, even extending into 20th-century confessional poetry, which scholars have frequently compared to the classic religious act of confession.2315
