Athanasius: Defending the Faith against Heresy
Athanasius, a prominent figure in the fourth century, fought diligently against heresy and played a crucial role in preserving the Christian faith. Born around AD 298 in Alexandria, Egypt, Athanasius lived in a time when Christianity transitioned from being a persecuted religion to an officially sanctioned one under Emperor Constantine's Edict of Milan in AD 313.
One of the significant challenges Athanasius faced was the spread of Arianism, a heretical belief propagated by Arius of Alexandria. Arius taught that Jesus, being begotten by God, did not exist eternally and was a created being rather than the eternal Son of God. As a newly ordained deacon and secretary to Bishop Alexander of Alexandria, Athanasius immediately refuted Arius' teachings, emphasizing the eternal relationship between the Father and Son.
Arius, however, gained support and moved to Nicomedia in Asia Minor, where he continued promoting his heretical views through letters to church bishops worldwide. The disagreement over Christ's divinity led Emperor Constantine to convene the Council of Nicaea in AD 325. Athanasius attended as a lead spokesman for the orthodox view that the Son is fully God and co-equal and co-eternal with the Father.
At the council, the majority agreed on Athanasius' view. To express this consensus, the council sought to formulate a creedal statement based on Scripture. However, the Arians managed to interpret these drafts in line with their own beliefs. Eventually, the term "homoousious," meaning "of the same substance or nature," was introduced to prevent further distortion of the orthodox position. Despite initial reluctance from some bishops due to its absence from Scripture, they recognized that clarity on Christ's true nature was essential. This led to the adoption of what is now known as the Nicene Creed, affirming the Son as "begotten, not made, being of one substance with the Father."
Unfortunately, not all accepted the council's decision. The Arians continued to reject it, and various compromises and variations of the Nicene Creed were proposed. In 328, Athanasius succeeded Bishop Alexander as the leader of Alexandria. He refused to compromise on such a crucial matter and declined negotiations with the Arians. Athanasius believed that prioritizing common ground over sound doctrine would lead to the loss of truth.
Athanasius' unwavering dedication to defending the full deity of Christ against opposition from emperors and theologians earned him the reputation of being a troublemaker. He was banished multiple times from his city and church. Despite facing severe opposition, Athanasius remained steadfast in his defense of biblical truth, earning him the phrase "Athanasius against the world."
Over time, Christians who upheld Christ's deity realized that abandoning the Nicene Creed would diminish the Son's role to that of a high-ranking angel. The careful wording of the creed accurately expressed biblical truth. In 381, at the Council of Constantinople, the Nicene Creed was reaffirmed, marking a final triumph that Athanasius did not witness before his death in 373.
Athanasius made significant contributions beyond defending the faith. As the bishop of Alexandria, he was responsible for providing the correct date for Easter to other bishops each year. His annual letters contained additional material, including a well-known Easter letter that listed books suitable for devotional reading and outlined which books should be considered part of the canon of Scripture.
In Athanasius' list for the New Testament, he included all 27 books recognized today. For the Old Testament, his list aligned with that used by most Protestants but omitted Esther while including Baruch. Additionally, Athanasius included a supplementary list of devotional books, such as Wisdom, Sirach, Tobias, Judith, and Esther.
Athanasius lived during a tumultuous period in church history, and his insights, courage, and steadfastness deserve our gratitude. With his profound knowledge of Scripture, Athanasius discerned the wolves in sheep's clothing infiltrating the church. Through his commitment to biblical truth, he stood firm against their attacks. We can learn from his example and appreciate the importance of defending and preserving the faith entrusted to us.
Why This Matters
Athanasius' fight against heresy highlights the significance of contending for the faith. As Christians, we are called to defend biblical truth amidst challenges and false teachings that may arise. Athanasius' unwavering commitment encourages us to stand firm, even when faced with opposition or persecution. His determination to preserve the full deity of Christ serves as a reminder of the foundational truths of our faith that must not be compromised.
Think About It
Consider the impact that Arius' heretical teaching would have had on Christianity if left unchallenged. What would it mean for our faith if Jesus were merely a created being rather than the eternal Son of God? Reflect on the importance of understanding and upholding the biblical truth about Christ's nature and its implications for our salvation. How can we learn from Athanasius' example in defending essential doctrines of our faith in today's context?
