Opening the mouth and uttering mystery belong to the scriptural motto that begins Part Four. The speaker will speak in a parable and disclose what is hidden from the world’s beginning. This authorizes the section’s mode of explanation through figurative speech; it is not a promise that every word will be literal or technically explicit.

The combined Psalm 78 and Matthew 13 heading is part of the supplied framing and should not be replaced with a single silently standardized citation.
