Reading about the Origen homilies discovered last Holy Thursday, it turned out that Origen talked about “parresia,” which Perrone defined informally as “freedom of speech.” (Remember all those times when you read about various Biblical figures speaking out boldly? That’s “parresia.” It also implies being candid, not holding things back that people need to hear. There’s an alternate spelling, “parrhesia.”)
Anyway, Perrone talked about how Origen talked about how the imperative (command form of a verb) being directed to God in the “Our Father” was a consequence of the freedom of speech (parresia) accorded to the righteous as adopted children of God. Those who obey God are commanded by God to command Him, in a way. (Video of the lecture. Copy of the paper.)
Pope Francis mentioned parresia back on St. George’s Day.
It would seem that a lot of Christians do speak in a reserved or frightened or politically correct way, instead of using parresia.
