The Apocalypse of Simeon Kepha is an apocalyptic text attributed to Peter the Apostle.
[2] Its main characteristic is lamentation over the deterioration of Christian faith in general and allusions to bribed judges initiating persecutions and martyrdoms.
[5] The codex contains a variety of documents such as letters by Jacob of Edessa, an excerpt by Severus of Antioch, a variety of apostolic canons, discussions of individuals who recant their heresy, and an investigation of heavenly entities.
[3] The Apocalypse of Simeon Kepha makes an assessment on Orthodoxy; it's being isolated as a minority and diminishing from the world because many falsify their allegiance to Christ, speak in an unacceptable manner, and create division amongst Christians.
Now the Nestorians who claim to be more knowledgeable about Jesus, will gain tribute, pillage, and create many evils that will cause destruction everywhere.
