Historical creeds are formal statements of faith that summarize core beliefs of a religious tradition. They often arise in response to theological disputes or to clarify essential doctrines. Examples include the Nicene Creed and the Apostles' Creed, which outline foundational Christian beliefs about the nature of God, Jesus, and the Holy Spirit. These creeds serve as a unifying framework for believers, helping to maintain doctrinal consistency across different communities. They are often recited in worship services and play a significant role in teaching and affirming faith within various denominations, including Catholicism and Protestantism.
