Which of Martin Luther's disagreements with the Catholic Church do you think were the most influenced by the renaissance idea of humanism?

One of Martin Luther's key disagreements with the Catholic Church that was heavily influenced by Renaissance Humanism was his emphasis on individual interpretation of Scripture. Humanism's focus on the value of the individual and critical thinking encouraged Luther to challenge the Church's authority and advocate for personal faith. Additionally, his rejection of the sale of indulgences reflected humanist ideals by prioritizing moral integrity over institutional corruption. These ideas collectively contributed to the broader Reformation movement, emphasizing personal conscience and direct access to God.
