When we think of lost gospels, the Gospel of Thomas or Mary Magdalene often come to mind. But there is one text so explosive, so dangerous to the medieval church’s authority, that it was hunted down and nearly erased from history: The Secret Supper, also known as the Interrogatio Johannis (The Interrogation of John).

This was no ordinary apocryphal text. To the Cathars, the medieval dualist movement of southern France, it was a sacred scripture. To the Catholic Church, it was a cosmic threat—one that undermined the very foundation of Christianity as they taught it.

What Is The Secret Supper?

The Interrogatio Johannis is a dialogue between Jesus and John the Apostle, where John asks about the origin of the world, the nature of evil, and the true God.

But the answers Jesus gives flip the biblical story upside down:

• The creator of this world is not the true God but the Demiurge—Satan disguised as the creator.
• Humanity was trapped in flesh by this false god. Birth itself is a prison for the soul.
• The Bible’s Old Testament laws and sacrifices are exposed as deceptions crafted by Satan to keep humanity enslaved.
• Even Moses on Mount Sinai did not meet the God of Light but the prince of darkness masquerading as God.

For the Cathars, this was the key to understanding reality: this world is hell in disguise, and Jesus was sent by the true God of Light to wake us up and show us the way back to the spiritual realm.

Why Was It Dangerous?

Rome could not allow this text to circulate because it directly attacked their theology:

1. It denied the authority of the Old Testament god.
   If Moses spoke to Satan, then the law was never divine.
2. It rejected material sacraments.
   Baptism, marriage, the Eucharist—if matter is evil, then rituals tied to flesh are meaningless.
3. It empowered individuals over institutions.
   Salvation came through awakening and gnosis (knowledge), not through church rituals or priests.

For these reasons, the Secret Supper was placed on the Index of Forbidden Books and targeted by the Inquisition. To possess a copy was to risk death.

Where Was It Found?

Ironically, copies of the Interrogatio Johannis survived in the very halls of the Inquisition itself. Medieval inquisitors kept it as evidence of heresy during trials against the Cathars. From these preserved manuscripts, modern scholars have been able to reconstruct the text.

Today, fragments and translations can be found in academic collections and Gnostic text libraries. The Gnostic Society Library and various scholarly publications offer English translations.

Core Teachings of the Secret Supper

1. The True God vs. The False God
   Jesus reveals that the God of Light is beyond creation, pure spirit, while the god of this world is the devil.
2. The Trap of Flesh
   Birth into this world is not a blessing but a prison. Souls are lured into flesh by deception.
3. The False Law
   The Ten Commandments and sacrifices of the Old Testament were not divine gifts but satanic tools of control.
4. Jesus’s True Mission
   He did not come to die for sins but to expose the lie—that the god worshipped by Israel and the church was actually the Adversary.

Why It Matters Today

The message of the Interrogatio Johannis feels shockingly modern:

• Don’t trust appearances. The systems claiming to represent God may serve the opposite.
• The true divine spark is within. We don’t need priests, popes, or corporate religions to find God.
• This world is not our home. Matter is a trap, and awakening is the only way out.

The Cathars died for believing this. Their crusade was not against armies but against the biggest lie in human history: that the god of this world is the God of all.
