19. αὕτη δέ ἐς. ἡ κρ. But the judgment is this; this is what it consists in. We have precisely the same construction 1Jn 1:5; 1Jn 5:11; 1Jn 5:14; and almost the same (ἵνα for ὅτι) Joh 15:12, Joh 17:3.
τὸ φῶς. This is not only S. John’s term (Joh 1:4-9) but Christ’s (Joh 8:12, Joh 9:5, Joh 12:46). On ἐλήλ. εἰς τ. κ. see on Joh 11:27.
καὶ ἠγαπ. The tragic tone again (see on Joh 1:5). Men loved the darkness rather than the Light. Litotes or meiosis (Joh 6:37, Joh 8:40); they hated the Light. Gravis malae conscientiae lux, Seneca, Ep. 122. No allusion to Nicodemus coming by night: he chose darkness to conceal not an evil work but a good one.
