Greek Fathers
Eastern Christian Teachers Who Defended and Explained the Faith
Who Were the Greek Fathers?
The Greek Fathers were early Christian writers, bishops, theologians, and saints who often wrote in Greek and were especially influential in the Eastern Church.
They helped explain the Trinity, defend the divinity of Christ, clarify the Incarnation, interpret Scripture, and guide Christian worship and doctrine.
