Mysterion μυστήριον

Mysterion (μυστήριον), thirty occurrences in the Naassene report and one of its organising terms.

Three words that are not synonyms

Refutatio 5.7.1 uses three in a single sentence, and an English translation that flattens them loses the report’s own distinctions:

• teletai — the rites, the ceremonies as instituted
• orgia — the ceremonies as performed
• mysteria — what is withheld within them

Hekhal keeps “rites”, “orgies” and “mysteries” distinct throughout for this reason. The charge the reporter is making depends on the distinction: he says the group gathers “the hidden and unspeakable mysteries of all the nations at once” and passes them off as Christian.

Rendering

“Sacrament” is a forbidden rendering. It imports a later Christian technical vocabulary into a text whose relation to mystery-cult practice is one of the disputed questions about it, and would let the reader assume an answer the passage does not give. “Secret” is forbidden as too thin: mysterion is withheld knowledge within an institution, not merely something concealed.

Cross-tradition resonance

• Arrhetos (gnostic-tradition) — the mysteries are characterised as unspeakable, and the two words travel together in this corpus.
