§3 The Credibility of the Gospel Paul Proclaims (Gal. 1:11–12)
1:11–12 / Paul continues his self-defense by focusing on the gospel itself. This is Paul’s usual way of underscoring his authority and credibility. For instance, at the beginning of Romans—a letter in which Paul wishes, among other things, to encourage the Roman believers to accept his apostolic authority—Paul highlights his understanding of and commitment to the gospel (Rom. 1:1–6). At the start of Galatians Paul also turns his hearers’ attention to the gospel. Paul was so thoroughly identified with the gospel he preached, both in his own mind and in the minds of others, that the most direct way to establish his credibility was to argue for the truth of the gospel he proclaimed. This focus explains why he now uses the first person singular “I” when talking about the preaching of the gospel, whereas before he had used the first person plural “we” (vv. 8–9). The issue he wishes to address for the sake of his hearers is the connection between his own trustworthiness and that of the gospel he preached to them. Furthermore, the way the semantic rhythm and rhetorical intention of verses 11–12 echo verse 1 suggests again that to Paul the issue of his apostolic credibility is one with the issue of the credibility of the gospel.
Paul affirms that the gospel he preached is not something that man made up, as proven by the fact that he did not receive it from a human being but rather by revelation from Jesus Christ. His gospel is therefore above criticism, and so it cannot be changed or added to, even by an angel from heaven. This is also why Paul himself, as the preacher of the gospel, should be trusted.
1:12 / I received it by revelation from Jesus Christ: In v. 17 the apostle says he “returned to Damascus,” which would suggest that this experience of God revealing God’s Son to Paul took place in Damascus (cf. Acts 9). The Greek for the phrase “by revelation from Jesus Christ” can mean either that Jesus Christ is the content of the revelation or that he is the bringer of the revelation. In connection with v. 16a it might seem most reasonable to opt for the former reading—that the substance of the revelation was Jesus Christ (so F. F. Bruce, The Epistle to the Galatians [The New International Greek Testament Commentary; Grand Rapids: Eerdmans, 1982], p. 89). In connection with v. 1, with which vv. 11–12 have semantic resonances, it seems appropriate to understand Jesus Christ as the means by which the revelation was given to Paul (so Longenecker, Galatians, p. 24). Perhaps the phrase should be understood in both ways at once: Jesus Christ is the content and the bringer of the gospel. Paul’s apostleship came through Jesus Christ (v. 1), and the gospel revealed to him was about Jesus Christ (v. 16). The revelation he speaks of in v. 12, then, concerns both content and means.
