So, we believe in the material sufficiency of the Gospel?

To be precise, the Coptic Orthodox Church affirms that the Holy Scriptures contain the essential "material" of our faith, but we do not subscribe to the Protestant interpretation of sufficiency that excludes the Church's authority or Holy Tradition.

In Coptic theology, the relationship between the Gospel and the Church can be understood through these points:

1. Material vs. Formal Sufficiency

• Material Sufficiency: We believe that the Holy Scriptures contain all the fundamental truths necessary for our salvation. There is no "new" revelation outside of what is contained in the deposit of faith.
• Formal Sufficiency: We reject the idea that the Bible is "formally sufficient"—meaning we reject the claim that the Bible is so clear that any individual can interpret it correctly without the guidance of the Church. Heretics throughout history, such as Arius or Nestorius, quoted the Bible extensively; their error was not a lack of Scripture, but a lack of the "mind of the Church".

2. The Gospel Was Entrusted to the Church

The Gospel existed in the Church as an oral Tradition before it was ever written down. The Church was the authority that defined the Canon. Therefore, the Bible is a product of the Church’s Tradition. St. Athanasius the Apostolic, in his 39th Festal Letter, listed the books of the New Testament exactly as we have them today to protect the faithful from the "secret" books of the heretics. For a Coptic Orthodox Christian, the Bible is sufficient because it is the written Record of the Tradition.

3. The Role of the Holy Fathers

We believe that the Holy Spirit, who inspired the writers of the Gospel, also inspires the Holy Fathers and the Councils to interpret that Gospel. St. John Chrysostom and St. Cyril of Alexandria are vital because they provide the correct "key" to unlocking the material found in the Scriptures. Without this key, people (like the Jews or various heretics) read the Material but fail to find the Truth.

4. The Biblical "Material" Requires the Sacraments

The Gospel itself points away from a "text-only" faith. The material in the Gospel tells us to:

• Be born of water and Spirit.
• Eat the Flesh and drink the Blood of the Son of Man (The Eucharist - - pi-mysterion).
• Confess our sins to one another (Repentance and Confession).

If one claims the Gospel is sufficient but rejects the Priesthood or the Real Presence of Christ in the Eucharist, they are actually contradicting the very "material" they claim to follow.

Summary

Yes, the Material is all there in the Holy Scriptures, but it is Holy Tradition that provides the correct interpretation, and the Sacraments that allow us to participate in the life described by that Material. We do not say "The Bible is enough"; we say "The Bible is the inspired written word of God, understood and lived within His Holy Church."
