Pope Leo XIV warned priests in Rome against using ChatGPT and similar AI tools to prepare sermons during a February closed-door meeting. The pontiff framed this as a form of 'deskilling,' arguing that relying on AI erodes the intellectual muscle priests need to effectively preach the faith. 'Like all the muscles in the body, if we do not use them, if we do not move them, they die,' he stated. The Vatican News report underscores a growing institutional concern about AI's encroachment into spiritual practices, distinct from broader societal debates about AI's impact on jobs or energy consumption. Pope Leo XIV's directive highlights the Church's proactive stance against AI's potential to depersonalize core religious functions.
