Subjunctive Protasis and Aorist Indicative Apodosis

Question

ἐὰν μή τις μένῃ ἐν ἐμοί, ἐβλήθη ἔξω ὡς τὸ κλῆμα ... (John 15:6)

μένῃ is present subjunctive and ἐβλήθη is aorist indicative. In many grammar books, there are two types of conditional sentence which begin with a subjunctive verb:

(1)

PRESENT GENERAL CONDITIONAL SENTENCE

Protasis: ἐὰν + subjunctive

Apodosis: present indicative

(2)

FUTURE MORE VIVID CONDITIONAL SENTENCE

Protasis: ἐὰν + subjunctive

Apodosis: future indicative

In John 15:6, the apodosis is aorist indicative. To which type of conditional sentence does this structure belong?

Answer 1

It's still a present general conditional. You might have noticed in some grammars that they will say for the present general apodosis, it takes the "present indicative or an equivalent." The aorist is the equivalent here, and functions as a gnomic aorist.

See Smyth § 2338:

2338. The gnomic aorist is equivalent to the present indicative in apodosis.
      ἢν δέ τις τούτων τι παραβαίνῃ, ζημίαν αὐτοῖς ἐπέθεσαν but if any one ever transgresses any one of these regulations, they always impose punishment upon them (him) X. C. 1.2.2.

You can do the same for John 15.6:

If anyone does not remain in me, they are cast out like a twig.
