John 15 - Cornerstone Biblical Commentary

15:1-6 It is common to interpret the vine mashal (see note on 10:6) in a sacramental way as eucharistic (so Brown, Barrett), due to its setting in the Last Supper scene and the use of “vine” in the Synoptic Last Supper accounts (“I will not drink again of the fruit of the vine until that day . . .” [NIV]). But it is far more likely that the vine symbol represents Israel, and Christ is showing that the new community, the true Israel, must be found in him (as discussed in the commentary below).

15:1-17 There are almost as many outlines of this section as there are scholars. Bruce, Schnackenburg, and Witherington see it as 15:1-11, 12-17; Bultmann, Michaels, Carson, and Ridderbos as 15:1-8, 9-16 (17); Brown and Whitacre as 15:1-6, 7-17; Burge as 15:1-8, 9-11, 12-17. One key decision is whether 15:7-8 belongs with the illustration or as part of the explanation. It seems to me that the themes of remaining and bearing fruit begin the interpretation and belong with the latter category. Also, 15:9-17 breaks naturally into two parts and with the inclusion of 15:7-8, we have a three-part explanation of the extended metaphor—15:1-8, 9-11, 12-17. This seems to be the most natural breakdown of the passage.

15:2-3 cuts off . . . prunes . . . purified. There is a strong play on words in the Gr., in which the heavenly Gardener “cuts off” (airei [TG142, ZG149]) the dead branches and “prunes” (kathairei [TG2508, ZG2748]) the fruitful ones, while the disciples are already “purified” (katharoi [TG2513, ZG2754]) (cf. Bruce, Carson). Note the similar sound of the final two syllables of each word. The emphasis is on the contrast between the removal of dead branches/disciples and the pruning/purification of the faithful disciples. The purification process is not explained here but probably would be the trials of life that God uses to help the believer grow in faith (cf. Heb 12:6-11; Jas 1:2-4; 1 Pet 1:6-7).

15:4 Remain in me. There may be a slight conditional force in this (“if you remain . . . I will remain”). This is represented in the NLT (“Remain in me, and I will remain in you”). In this sense, the disciples’ perseverance in Jesus would be “the occasional cause, not the ultimate cause, of Jesus remaining in the believer (Cf. 8:31-32; 15:9-11)” (Carson 1991:516).

15:7-17 Some scholars (Brown, Whitacre) think this passage is a chiasm, with teaching (15:7, 17) and answered prayer (15:7, 16) framing the section, and joy (15:11) in the center. Some of the parallels are difficult to maintain, however, and the threefold outline here seems better.

15:13 lay down one’s life for one’s friends. Some critics have called this a lesser passage than Rom 5:8, for surely dying for one’s enemies is greater than dying for one’s friends. Yet that is hardly the point. As Morris says (1995:599), “He is in the midst of friends and is speaking only of friends. With respect to them he is saying that one cannot have greater love than to die for them.”

15:20 if they had listened to me, they would listen to you. This can be interpreted two ways: negatively—“if they had listened to me (which they haven’t), they would listen to you (which they won’t)” (so Brown, Whitacre, Burge, Köstenberger); or positively—“if they listened to me (some did), they will listen to you (some will)” (so Barrett, Schnackenburg, Comfort, Carson). The question is the relationship between the negative “since they persecuted me” statement to the parallel “if they had listened” statement. A case can be made for the positive as providing the two sides of ministry: persecution and positive response to the Gospel. This would be favored by Jesus’ prayer for “all who will ever believe in me through their message” (17:20). The immediate context (15:18-25), however, is completely negative and thus this statement would fit parallels in Isa 6:10 (where Isaiah is told to “harden the hearts of these people . . . plug their ears and shut their eyes”) and Ezek 3:7 (“the people of Israel won’t listen to you any more than they listen to me”). The disciples would be persecuted, and their message would be rejected, just as Jesus was.

15:26 the Spirit of truth. The emphasis here is on the Spirit as a person, seen in the masculine “he” (ekeinos [TG1565, ZG1697]) following “Spirit.” Carson (1991:528-529) speaks of the “procession” of the Spirit from the Father and of the Trinitarian basis of this passage. The Spirit comes from the Father and is sent by the Son on his mission; the Godhead is acting together in unity in responding to the world’s opposition.

15:27 you have been with me from the beginning of my ministry. This verse has its primary application with the historical disciples (so Carson, Whitacre). Since they were eyewitnesses from the start (cf. Luke 1:2; Acts 1:21-22; 2 Pet 1:16), they were the divinely chosen witnesses. For the early church, historical proof of the accounts was extremely critical. Moreover, this concern for verifiable history on the part of the early church is important to us in an age when many critical scholars are dismissing the verifiability of the Gospel accounts. Still, it is also valid for us to contextualize this as a promise that the Spirit will continue to empower our witness today.
