Patristics is the study of the early Christian writers known as the Church Fathers. These theologians and scholars lived from the late first century to the eighth century and played a crucial role in shaping Christian doctrine and practice. Their writings include letters, sermons, and theological treatises that address various aspects of faith, morality, and church governance. The field of Patristics examines the historical context, literary style, and theological contributions of these figures. Key figures in Patristics include St. Augustine, St. Jerome, and St. Athanasius, whose works continue to influence Christian thought and are studied for their insights into early Christianity.
