By revelation (kata apokaluyin). Not essentially different from di apokaluyewv (Galatians 1:12). This was Paul's qualification for preaching "the mystery" (to musthrion. See Ephesians 1:9).
As I wrote afore (kaqwv proegraya). First aorist active indicative of prografw as in Romans 15:4, not picture forth as Galatians 3:1. But when and where? Epistolary aorist for this Epistle? That is possible. A previous and lost Epistle as in I Corinthians 5:9? That also is abstractly possible. To the preceding discussion of the Gentiles? Possible and also probable.
In few words (en oligw). Not = pro oligou, shortly before, but as in Acts 26:28 "in brief space or time" = suntonwv (Acts 24:4), "briefly."
