Revelation 1:1-3

The superscription. Ἀπ. Ἰωάννου is the ecclesiastical title (distinguishing it from the apocalypse of Peter, or of Paul, etc.) of what professes in reality to be an ἀπ. Ἰησοῦ Χριστοῦ (subjective genitive), i.e., a disclosure of the divine μυστήρια (Daniel 2:19; Daniel 2:22; Daniel 2:28, Theod.) in the immediate future (ἃ δεῖ γ. ἐν τάχει) which has been communicated (ἔδωκεν, cf. on Revelation 3:9) by God to Jesus (cf. Revelation 5:7) and which in turn is transmitted by Jesus (Galatians 1:12) to John as a member of the prophetic order.
