Christ. From Fritzsche in Fritzschiorum opuscc., p. 20ff; (in Ignatius ad Philad. 9 [ET] Christ is called ἡ θύρα τοῦ πατρός, δἰ ἧς ἐισερχονται Ἀβραάμ ... καί οἱ προφῆται; cf. Harnack on Clement of Rome, 1 Cor. 48, 3f [ET]). β. 'an open door' is used of the opportunity of doing something: τῆς πίστεως, of getting faith, Acts 14:27; open to a teacher, i. e. the opportunity of teaching others, 2 Corinthians 2:12; Colossians 4:3; by a bold combination of metaphor and literal language, the phrase θύρα μεγάλη καί ἐνεργής (A. V. a great door and effectual) is used of a large opportunity of teaching a great multitude the way of salvation, and one encouraging the hope of the most successful results: 1 Corinthians 16:9. γ. the door of the kingdom of heaven (likened to a palace) denotes the conditions which must be complied with in order to be received into the kingdom of God: Luke 13:24 (for Rec. πύλης); power of entering, access into, God's eternal kingdom, Revelation 3:8 cf. Revelation 3:7 (but others besides; add here Revelation 4:1). δ. he whose advent is just at hand is said ἐπί θύραις εἶναι, Matthew 24:33; Mark 13:29, and πρό θυρῶν ἑστηκεναι, James 5:9. ε. ἑστηκώς ἐπί τήν θύραν καί κρούων is said of Christ seeking entrance into souls, and they who comply with his entreaty are said ἀνοίγειν τήν θύραν, Revelation 3:20.
