John 8:19

8:19 Then they began asking ¹  him, “Who is your father?” Jesus answered, “You do not know either me or my Father. If you knew me you would know my Father too.” ² 

John 14:7

14:7 If you have known me, you will know my Father too. ³  And from now on you do know him and have seen him.”

[8:19]  ¹ tn Grk “Then they were saying to him.” The imperfect verb has been translated with ingressive force here because of the introduction of a new line of questioning by the Pharisees. Jesus had just claimed his Father as a second witness; now his opponents want to know who his father is.

[8:19]  ² sn If you knew me you would know my Father too. Jesus’ reply is based on his identity with the Father (see also John 1:18; 14:9).

[14:7]  ³ tc There is a difficult textual problem here: The statement reads either “If you have known (ἐγνώκατε, egnwkate) me, you will know (γνώσεσθε, gnwsesqe) my Father” or “If you had really known (ἐγνώκειτε, egnwkeite) me, you would have known (ἐγνώκειτε ἄν or ἂν ἤδειτε [egnwkeite an or an hdeite]) my Father.” The division of the external evidence is difficult, but can be laid out as follows: The mss that have the perfect ἐγνώκατε in the protasis (Ì⁶⁶ [א D* W] 579 pc it) also have, for the most part, the future indicative γνώσεσθε in the apodosis (Ì⁶⁶ א D W [579] pc sa bo), rendering Jesus’ statement as a first-class condition. The mss that have the pluperfect ἐγνώκειτε in the protasis (A B C D¹ L Θ Ψ Ë^1,13 33 Ï) also have, for the most part, a pluperfect in the apodosis (either ἂν ἤδειτε in B C* [L] Q Ψ 1 33 565 al, or ἐγνώκειτε ἄν in A C³ Θ Ë¹³ Ï), rendering Jesus’ statement a contrary-to-fact second-class condition. The external evidence slightly favors the first-class condition, since there is an Alexandrian-Western alliance supported by Ì⁶⁶. As well, the fact that the readings with a second-class condition utilize two different verbs with ἄν in different positions suggests that these readings are secondary. However, it could be argued that the second-class conditions are harder readings in that they speak negatively of the apostles (so K. Aland in TCGNT 207); in this case, the ἐγνώκειτε…ἐγνώκειτε ἄν reading should be given preference. Although a decision is difficult, the first-class condition is to be slightly preferred. In this case Jesus promises the disciples that, assuming they have known him, they will know the Father. Contextually this fits better with the following phrase (v. 7b) which asserts that “from the present time you know him and have seen him” (cf. John 1:18).
