(Exodus 7:1-5, Nehemiah 9:9-21; Hebrews 5:11-6:12)
So a couple times now, the book of Hebrews has quoted Psalm 110 and the line, “You are a priest forever according to the order of Melchizedek.” You might be wondering what that’s all about. Most likely, so were the people to whom this book was addressed. As such, you might have expected the author to move on and explain himself, because the Melchizedek reference isn’t obvious by any means; it’s going to take some unpacking, and it’s clearly important to where the author is going. But he doesn’t do that; instead, he gives them another warning. This is the fourth so far, but it’s the first of the two big ones in this book, and it’s fairly complex in its argument, so we need to unpack it carefully; there’s a lot that it’s easy to miss.
The key thing to remember is what the author has just been arguing, in the passage we read last week: Christ has fulfilled the core purpose of the law, he has completed in full, once and for all, the work that the priests and the sacrificial system could only do partially and temporarily, and so he has replaced the priests and their sacrifices. He is the final and greatest high priest who has offered the final sacrifice; nothing else is necessary, and nothing else accomplishes anything. The priests can continue offering their sacrifices if they want to, but those sacrifices are empty, meaningless, unheeded by God and outside his will—as indeed any human religious activities that are not centered on Christ are empty, meaningless, unheeded by God and outside his will. That may be the way things always used to be done, but it’s all served its purpose, and has now outlived it; God is no longer in it, and to the extent that the old sacrificial system now stands opposed to the worship of his Son, he’s actively opposed to it, and to all who maintain it.
This is, of course, a hard thing to hear; after all, this is an epistle to the Hebrews, to Jewish Christians who surely loved and valued their heritage and everything that went along with it. No doubt they understood the author’s point, at least to some degree; the question was, were they willing to accept all its implications? Were they willing to move on from their heritage, to accept that the law had fulfilled its purpose and the sacrificial system was no longer necessary? And in particular, were they willing to do so if it meant standing up to those who refused to accept that fact?
It seems clear that they were not willing; hence the author’s complaint in the end of chapter 5. “You’re going to have a hard time understanding this,” he tells them, “because your minds have become sluggish. You ought to be teaching this to others yourselves, but instead you’re making me go over the basics all over again. You’re refusing to act your age, you’re refusing to be mature—you’re acting as if you don’t understand all this, as if you still need to be treated as spiritual babies.” It’s not that they hadn’t been taught, it’s not that they didn’t know enough to know what was right, or what they were supposed to be doing; but they were sluggish, they didn’t want to actually do it, because they didn’t like the next steps they were supposed to take. They didn’t want to take the risk of faith, they didn’t want their friends who were still Jews turning against them; they had faced some persecution for Christ in the past, but if they bought in completely to what Hebrews is saying, they’d have a lot more to deal with, and they didn’t want that.
That’s why the author wasn’t able to just start off talking about Jesus as our great high priest, and why he can’t just plow right on and teach them about Melchizedek; it’s why he had to build up to that point with his other arguments, and why at every stage of his argument—including this one—he’s felt the need to offer a warning, to make sure his audience is taking him seriously and listening closely to what he’s trying to tell them. Clearly, though, he’s had enough of laying the groundwork, enough of talking about the basics; and in fact, he says, therefore, let’s press on to talk about the high priesthood of Christ. Why therefore? Because the problem isn’t that these Jewish Christians don’t understand this stuff. They understand it just fine. They just think they can get away with not committing to it, not living it out; they think they can keep one foot in the gospel and one foot in their old world—which in their case happens to be the world of Judaism and the Jewish law—and they’ll be just fine. In response, Hebrews sets out to show them how wrong they are, and why.
Now, the biggest part of that is coming beginning in chapter 7, where the author does exactly what he says he’s going to do and teaches them in detail about the high-priestly work of Jesus; when we get there, we’ll take several weeks to explore that, because he’s not kidding when he says it’s hard to explain. We’ll get there, and it’s worth it, but it does take some effort. First, though, he reminds them what they’re called to—“repentance from dead works and faith in God”—and lays out the consequences of turning away from Christ and that calling. Those consequences are severe; nothing less than salvation is at stake. It’s easy to slip into the mindset represented by the German Romantic poet Heinrich Heine, who once wrote, “I love to sin. God loves to forgive sin. Really, this world is admirably arranged.” The truth is very different. It is not that God loves to forgive sin; rather, he loves us and so he paid a horrendous price in the sacrifice of his Son in order that we might be forgiven. To sin casually is to take his forgiveness lightly, and to do that is to take the sacrifice of Christ lightly; and that is profoundly serious, and profoundly wrong, and not something God will simply brush off.
Now, it’s important to recognize that Hebrews here isn’t just talking about sin. There have been those who have tried to argue from this passage that any sin after conversion is unforgivable, and that’s just not the point here; this passage won’t support that, nor would that square with the rest of the New Testament. Rather, we’re talking about a very specific thing, one which is quite unfashionable to talk about these days: the sin of apostasy. This is the sin of those who are a part of the church—who have heard the gospel, who have seen its goodness and experienced its power, who have participated in its communion—and then have wilfully turned their back on it and chosen another way. Such people, Hebrews says, have deliberately chosen to crucify Christ all over again and to put him to public shame, and so for them, any return to repentance is impossible.
Now, does that merely mean it’s humanly impossible, or is Hebrews saying this is even impossible for God? Honestly, I don’t know. On the one hand, Jesus says, “With God, all things are possible.” On the other, Jesus also calls blasphemy against the Holy Spirit the unforgivable sin. We’re in one of those areas where Scripture doesn’t really give us a nice neat conclusion tied up in a white satin ribbon. But the argument here is clear, and it does parallel Jesus’ statement about blasphemy against the Holy Spirit: if you reject the only means by which you may be saved, and the only way in which you can possibly repent, then you have nowhere else to go. Christ’s sacrifice was once for all, and nothing else is coming along to offer the same opportunity—if you decisively reject that, then you have locked yourself in a room with no windows and welded the door shut behind you, and there is no way out. There is no way but the One who is the Way, and if you turn your back on him, you have no way to go. Whatever else, this is certainly impossible by any sort of human effort or human choice.
There are those who have been arguing of late that our denomination is apostate; if you follow the news stories, you know why. For my part, I say it isn’t, for two reasons. One, I don’t believe a denomination, a bureaucratic and corporate structure, can be apostate, because it’s a thing. People are sinners, and commit sins, and we use many, many things to help us do so, but the things themselves are not guilty of sin. Two, it must also be said that what certain people, or certain collections of people, do is neither necessarily representative nor necessarily determinative of the denomination as a whole. General Assembly may well vote to reject the plain testimony of the word of God in any number of areas, but they aren’t the ones who decide; the presbyteries do, and so far, the presby-teries have swatted them down every time. What GA does gets the headlines, but it’s what the presbyteries do with it that matters, and that remains to be seen. So no, the Presbyterian Church (USA) isn’t apostate. But are we led by apostates? Are we led by people who have turned aside from the gospel to follow their own gods with their own laws? Ultimately, only God can judge that; but in some cases, there’s reason for concern. Which obviously means we must watch closely what they do and go carefully lest we be judged for following them, and believe me, we of the Session are doing exactly that.
The broader question that arises from this passage is, does Hebrews teach that you can lose your salvation? The answer is, if it does, it also teaches that you can only lose it once, and it’s gone forever—there’s no falling away and coming back and falling away and coming back—but I don’t believe that’s what’s in view here, because that isn’t where Hebrews goes with this. Rather, we see the author go on to express confidence that his readers haven’t fallen away from Christ, and aren’t going to, because God is faithful and their faith is real; like the field in verse 7, they have already produced real fruit. In Christ, they will escape the danger they face, the author has no doubt, because God won’t let go of them; but he still wants them to understand that danger and take it very seriously.
The truth is, we affirm the perseverance of the saints, that salvation is a work of God that we cannot undo, and that thus it’s impossible to “lose” our salvation; but nowhere does the Bible promise the perseverance of everyone we think is a Christian. Who are the saints? The saints are those who persevere. It’s why Paul stresses running to win, crossing the finish line, finishing well, fighting the fight all the way to the end; we can’t judge people’s hearts from the outside—we can barely judge our own. There are those who seem to run well for a while, but then they drop out, and in so doing, reveal that we misjudged them. It’s like Jesus says in the parable of the sower—it’s not just that the seed springs up that matters, it’s whether it can thrive despite the weeds, and whether the soil is deep enough to sustain the growth through the heat of the summer. And so Hebrews tells its audience, and us, not to get too impressed with ourselves, and not to take ourselves for granted; God is faithful, but we still need to keep running, to keep pressing on, to stay in the race, because we haven’t crossed the finish line yet.
The thing that makes this tricky is that it isn’t a matter of just working harder; this doesn’t boil down to “just grit your teeth and keep going.” That’s living by law; that is, ironically enough, one of the temptations we have to resist. In truth, I think it’s safe to say that a lot of folks who turn their backs on the church aren’t really turning their backs on the gospel, they’re turning their backs on that sort of “just do it” legalism; they aren’t rejecting Christ but a counterfeit, though that doesn’t necessarily make it any easier to get them to listen to the gospel. Following Christ, putting our faith in him alone, produces good works, but those good works are not the ultimate point, and our goal is not to get those good works by any means necessary; good works done in our own strength are like costume jewelry—they may glitter and sparkle on first appearance, but apply any pressure and they break. What God calls us to is, in truth, harder: to continue to live by faith, to continue to put our trust in the grace of God and the saving work of Christ, to continue to put to death our own egos and their demands for credit and attention, to continue to learn and accept humility and acknowledge that we are not enough, only Jesus is enough. It means setting aside the demands of our selves with our agendas and our plans, and letting ourselves be filled instead with the mind and the Spirit of Christ, that he would fill us and dwell in us, that he would mark out our way and direct our paths.
