Doctrines are formal beliefs or teachings that guide the practices and principles of a religious group or organization. In the context of the Catholic Reformation, doctrines played a critical role in defining the response of the Catholic Church to Protestant Reformation ideas, clarifying key beliefs, and reaffirming the authority of the Church. The establishment and reformulation of doctrines were crucial in unifying Catholic teachings and addressing the challenges posed by emerging Protestant ideologies.
