Communication is indeed “nearly always tricky,” but McLaren’s argument leads to interpretive nihilism. Can we really not know what the Gospel is? If this is true, the church is left with no coherent message at all. All of our attempts to define the right form of the Gospel are just human interpretations, he insists, and we must avoid “excessive confidence” in any telling of the Gospel story. McLaren warns that we must avoid “a naive and excessive confidence,” but that we can retain a “humble confidence.” But his argument leaves us with very little idea of how this “humble confidence” is to be found, since “no articulation of the gospel today can presume to be exactly identical to the original meaning Christ and the apostles proclaimed.”
That statement leaves us with only approximations of the Gospel — some presumably better, some worse. And we would in fact be left with nothing more precise or authoritative than that but for one thing — we have the Bible. We are absolutely dependent upon the New Testament way of telling the Gospel of Christ, and the apostles were determined to pass along the Gospel as a clear and understandable message to others. This is why Paul instructed Timothy to “follow the pattern of the sound words that you have heard from me, in the faith and love that are in Christ Jesus” and to “guard the good deposit entrusted to you.” [2 Timothy 1:13-14]
If we cannot know what the Gospel is, then there is no such thing as the faith “once for all delivered to the saints.” [Jude 3] If so, we have nothing definitive to say.
