The term "Church Fathers" refers to influential early Christian theologians and leaders who shaped the beliefs and practices of the Christian Church. They lived from the late first century to the eighth century and played a crucial role in interpreting scripture, defending the faith, and establishing church doctrine. Their writings laid the foundation for many core Christian teachings. Some well-known Church Fathers include St. Augustine, St. Jerome, and St. Athanasius. They addressed various theological issues, such as the nature of God, the role of Jesus Christ, and the importance of the Holy Spirit. Their contributions continue to be studied and respected in Christian communities today.
