ἐπιφάνεια, -ας, ἡ, (ἐπιφανής), an appearing, appearance (Tertullian apparentia); often used by the Greeks of a glorious manifestation of the gods, and especially of their advent to help; in 2 Macc. of signal deeds and events betokening the presence and power of God as helper; cf. Grimm on Maccabees, p. 60f, 75, [but especially the thorough exposition by Prof. Abbot (on Titus 2:13 Note B) in the Journal of the Society for Biblical Literature and Exegesis, i., p. 16f (1882)]. In the N. T. the 'advent' of Christ — not only that which has already taken place and by which his presence and power appear in the saving light he has shed upon mankind, 2 Timothy 1:10 (note the word φωτίσαντος in this passage); but also that illustrious return from heaven to earth hereafter to occur: 1 Timothy 6:14; 2 Timothy 4:1, 8; Titus 2:13 [on which see especially Prof. Abbot as above]; ἡ ἐπιφάνεια (i. e. the breaking forth) τῆς παρουσίας αὐτοῦ, 2 Thessalonians 2:8.
