Sunday School Lesson: The Holy Council of Nicaea (325 AD)

Objective: To understand the importance of the Council of Nicaea in defending the divinity of our Lord Jesus Christ and the formation of the Orthodox Creed.

I. Introduction: The Need for the Council

After the era of martyrdom ended with the Edict of Milan, the Church faced a new kind of danger: heresy. A priest from Libya named Arius began teaching a false doctrine in Alexandria. He claimed that there was a time when the Son of God did not exist and that He was a created being, not equal to God the Father.

This was a direct attack on the core of our salvation. If Jesus Christ is not God, He cannot save us.

II. The Gathering of the 318

In 325 AD, Emperor Constantine the Great called for a general council in the city of Nicaea. Traditionally, 318 bishops gathered from all over the world.

• The Confessors: Many of these bishops carried the physical scars of Roman persecution. Some were missing eyes, and others had burned hands, yet they remained "trained servants of the Most High," full of Apostolic gifts and the power of the Holy Spirit.
• The Key Figures:
• Pope Alexander: The 19th Pope of Alexandria, who first stood against Arius.
• St. Athanasius the Apostolic: At the time, he was only a young deacon serving Pope Alexander. He was the true hero of the council, using his profound theological wisdom to refute Arius's logic.
• St. Macarius of Jerusalem: Known for his many miracles.

III. The Theological Conflict

Arius tried to use philosophical logic and twisted interpretations of Scripture to prove the Son was inferior to the Father. However, St. Athanasius and the Holy Fathers explained that the Son is Consubstantial (of one essence) with the Father.

In Coptic, we describe the Trinity as The Consubstantial Trinity. We believe in one God: the Father, the Son, and the Holy Spirit.

IV. The Result: The Orthodox Creed

The Council condemned Arius as a heretic and excommunicated him. To ensure the Truth would be preserved forever, the 318 Fathers drafted the first part of the Creed (from "We believe in one God..." to "...His kingdom shall have no end").

Key points of the Creed from Nicaea:

1. Jesus Christ is the Only-begotten Son of God.
2. He is Light of Light, true God of true God.
3. He is begotten, not created.
4. He is of one essence (Homoousios) with the Father.

V. The Coptic Orthodox Perspective

Our Church recognizes only three Ecumenical Councils as authoritative in matters of faith:

1. Nicaea (325 AD): Condemned Arius.
2. Constantinople (381 AD): Condemned Macedonius (who denied the divinity of the Holy Spirit).
3. Ephesus (431 AD): Condemned Nestorius.

We do not accept the Council of Chalcedon or any thereafter, as they strayed from the Miaphysite faith handed down by St. Cyril and St. Athanasius. We remain steadfast in the faith of the 318 Fathers.

VI. Class Discussion/Activity

1. Memory Verse: "In the beginning was the Word, and the Word was with God, and the Word was God." (John 1:1)
2. Question: Why was it important for St. Athanasius to be at the council even though he was just a deacon?

• Answer: Because the Truth does not depend on rank, but on the grace of the Holy Spirit and a correct understanding of the Nature of Christ.

1. Application: Every time we pray the Creed in the Liturgy or the Agpeya, we are reciting the victory of Nicaea. We should say it with focus and strength, remembering the sacrifices of the Fathers.

Conclusion:

The Council of Nicaea provided an "everlasting bulwark" between the Church and heresy. Because of the courage of the 318, we can confidently worship Jesus Christ as our True God and Savior.
