Look again at the sayings given above. In none of them is there any hint that Jesus is talking about himself when he refers to the Son of Man coming in judgment on the earth. Readers naturally assume that he is talking about himself either because they believe that Jesus is the Son of Man or because they know that elsewhere the Gospels identify him as the Son of Man. But nothing in these sayings would lead someone to make the identification. These sayings are not phrased the way early Christians would have been likely to invent if they, rather than Jesus, had come up with them.
Or consider another saying, from Mark 8:38. Pay close attention to the wording: “Whoever is ashamed of me and of my words in this adulterous and sinful generation, of that one will the Son of Man be ashamed when he comes in the glory of his Father with the holy angels.” Now, anyone who already thinks that Jesus is the Son of Man may casually assume that here he is talking about himself—whoever is ashamed of Jesus, Jesus will be ashamed of him (that is, he will judge him) when he comes from heaven. But that’s not actually what the saying says. Instead, it says that if anyone is ashamed of Jesus, of that person the Son of Man will be ashamed when he comes from heaven. Nothing in this saying makes you think that Jesus is talking about himself. A reader who thinks Jesus is talking about himself as the Son of Man has brought that understanding to the text, not taken it from the text.
This is probably not the way an early Christian would have made up a saying about the Son of Man. You can imagine someone inventing a saying in which it is crystal clear that Jesus is talking about himself: “If you do this to me, then I, the Son of Man, will do that to you.” But it is less likely that a Christian would make up a saying that seems to differentiate between Jesus and the Son of Man. This means the saying is more likely authentic.
My second example is from one of my favorite passages of the entire Bible, the story of the last judgment of the sheep and the goats (Matt. 25:31–46; this is from M). We are told that the Son of Man has come in judgment on the earth, in the presence of the angels, and he sits on his throne. He gathers all people before him and separates them “as a shepherd separates the sheep from the goats” (25:32). The “sheep” are on his right side and the “goats” on his left. He speaks first to the sheep and welcomes them to the kingdom of God that has been prepared especially for them. And why are they allowed to enter this glorious kingdom? “Because I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me” (25:35–36). The righteous are taken aback and don’t understand: they have never done these things for him—in fact they have never even seen him before. The judge tells them, “Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me” (25:40). He then speaks to the “goats” and sends them away to the “eternal fire prepared for the devil and his angels” (25:41), and he tells them why. They didn’t feed him when he was hungry, give him a drink when he was thirsty, welcome him as a stranger, clothe him when he was naked, visit him when he was sick and in prison. They too don’t understand—they have never seen him before either, so how could they have refused to help him? And to them he says, “Truly, I say, to you, as you did it not to one of the least of these, you did it not to me” (25:45). And so we are told that the sinners go off to eternal punishment and the righteous off to eternal life.
It is a spectacular passage. And it almost certainly is something very close to what Jesus actually said. And why? Because it is not at all what the early Christians thought about how a person gains eternal life. The early Christian church taught that a person is rewarded with salvation by believing in the death and resurrection of Jesus. The Apostle Paul, for example, was quite adamant that people could not earn their salvation by doing the things the law required them to do, or in fact by doing anything at all. If that were possible, there would have been no reason for Christ to have died (see, for example, Gal. 2:15–16, 21). Even in Matthew’s Gospel the focus of attention is on the salvation that Jesus brings by his death and resurrection. In this saying of Jesus, however, people gain eternal life not because they have believed in Christ (they have never even seen or heard of the Son of Man), but because they have done good things for people in need. This is not a saying that early Christians invented. It embodies the views of Jesus. The Son of Man will judge the earth, and those who have helped others in need will be the ones who will be rewarded with eternal life.
My third example of a saying that almost certainly passes the criterion of dissimilarity is an apocalyptic saying that will be important for our discussion later in this chapter. In a saying preserved for us in Q, Jesus tells his twelve disciples that in the “age to come, when the Son of Man is seated upon his glorious throne, you also will sit upon twelve thrones judging the twelve tribes of Israel” (Matt. 19:28; see Luke 22:30). It doesn’t take much reflection to see why this is something that Jesus is likely to have said—that it was not put on his lips by his later followers after his death. After Jesus died, everyone knew that he had been betrayed by one of his own followers, Judas Iscariot. (That really did happen: it is independently attested all over the map, and it passes the criterion of dissimilarity. Who would make up a story that Jesus had such little influence over his own followers?) But to whom is Jesus speaking in this saying? To all the Twelve (meaning the twelve disciples). Including Judas Iscariot. He is telling them that they all, Judas included, will be rulers in the future kingdom of God. No Christian would make up a saying that indicated that the betrayer of Jesus, Judas Iscariot himself, would be enthroned as a ruler in the future kingdom. Since a Christian would not have made the saying up, it almost certainly goes back to the historical Jesus.
The Beginning and End as the Keys to the Middle
The combination of all these arguments I have mustered have persuaded the majority of critical scholars of the New Testament for more than a century that Jesus is best understood to have proclaimed an apocalyptic message. The final argument that I give now is, in my judgment, the most convincing of them all. It is so good that I wish I had come up with it myself.7 The argument is that we know with relative certainty how Jesus began his ministry, and we know with equal certainty what happened in its aftermath. The only thing connecting the beginning and the end is the middle—the ministry and proclamation of Jesus himself.
Let me explain. I earlier pointed out that we have good evidence—independent attestation and dissimilarity—of how Jesus began his public life—by being baptized by John the Baptist. And who was John the Baptist? A fiery, apocalyptic preacher proclaiming that the end of the age was coming very soon and that people needed to repent in preparation for it. John’s words are best recorded for us in a statement found in the Q document, delivered to the crowds: “Who warned you to flee from the wrath to come? Bear fruits worthy of repentance. . . . Even now the ax is lying at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire” (Luke 3:7–9). This is a thoroughly apocalyptic message. Wrath is coming. People need to prepare (by “bearing good fruit”). And if they don’t? They will be cut down like a tree and tossed into the fire. When will this happen? It is ready to start at any moment: the ax is already at the root of the tree, and the chopping is ready to begin.
