I don't particularly remember coming across this document - "The Statement on Social Justice and the Gospel" - at the time. I am not intending to comment on it as a whole. I do want to comment upon section 8, "The Church":
WE AFFIRM that the primary role of the church is to worship God through the preaching of his word, teaching sound doctrine, observing baptism and the Lord’s Supper, refuting those who contradict, equipping the saints, and evangelizing the lost. We affirm that when the primacy of the gospel is maintained that this often has a positive effect on the culture in which various societal ills are mollified. We affirm that, under the lordship of Christ, we are to obey the governing authorities established by God and pray for civil leaders.
WE DENY that political or social activism should be viewed as integral components of the gospel or primary to the mission of the church. Though believers can and should utilize all lawful means that God has providentially established to have some effect on the laws of a society, we deny that these activities are either evidence of saving faith or constitute a central part of the church’s mission given to her by Jesus Christ, her head. We deny that laws or regulations possess any inherent power to change sinful hearts.
These paragraphs reflect the concern of conservative evangelicals to guard against "the social gospel". In terms of the concerns that conservative evangelicals had/have, the social gospel would be seen as defining the mission of the church in terms of proclaiming Christ's love and advancing his kingdom by fighting against injustices in society. It is seen as the on-the-ground program of theological liberalism: the activities that churches give themselves to as their defining mission when the stop having the gospel of Christ incarnate, crucified, risen, ascended and returning, and all the consequences (such as the necessity of preaching this gospel, calling upon people to repent and believe upon him to receive salvation) at the heart of their life.
As always, there is the possibility of over-reaction. Christ commands his people to be zealous for good works. We are to demonstrate his love and compassion in action, and not only as a way of testifying to the gospel, but because the love of Christ dwells in us too and God's love is to be made known to the nations. A church that has no concern for good works does not reflect the Scriptures of either the Old or New Testament, which consistently testify to God's special concern for the suffering, the abandoned, the needy, in society.... and also consistently testify to his wrath against complacent religious people whose lifestyles proclaim that they do not particularly care.
I read the above section, its affirmations and denials, seeking to understand how the statement (i.e. its authors and endorsers) see these things.
Having read it, I'm still not sure, which is a curious thing.... because such statements are intended to remove ambiguity, to clarify, to advance understanding by being specific.
Why do I say this?
Firstly, the statement leaves an awful lot unsaid. The "primary" role of the church is spoken of. Does the church have secondary (or tertiary) roles? If so, what are they? Or is "primary role" a synonym for "only role" or "only required role", or something else? We're not told. The importance of maintaining the "primacy" of the gospel is maintained, which sounds good and something I am likely to agree with; but unfortunately it too is not explained. What things threaten the primacy of the gospel has to be inferred from the surrounding context, but there's multiple ways in which that could be done, so, we are left to give our best effort.
The church upholding the "primacy" of the gospel is said to "often" have a positive effect on society, by mollifying (Britannica dictionary: "to make (someone) less angry : to calm (someone) down"; Collins dictionary: "If you mollify someone, you do or say something to make them less upset or angry. ... Synonyms: pacify, quiet, calm, compose") societal ills; I wonder what that is intended to mean? Presumably in some way to reduce or remove, to a limited extent, those ills? To what end(s)?
So, having read the affirmations, a lot is unclear - but one of the good things about denials is that these can add a lot of clarity. Unfortunately....
... again, with the denials, the language is very ambiguous. Political or social activism (which are not defined, presumably have considerable overlap), are not to be viewed as "integral components" of the gospel. What would that mean? An earlier section defines the gospel as follows: "WE AFFIRM that the gospel is the divinely-revealed message concerning the person and work of Jesus
Christ". If the gospel is (which I agree with!) a divinely revealed message of good news about Jesus, then what would it mean for societal activism to be an "integral component"? Does it mean to deny that the doing of the good works is not itself part of the gospel? Or that proclaiming their necessity is not? Or something else? Since the gospel, by definition, is the proclamation of Christ, then the proclaiming of the importance of the church doing good works cannot be any "component" of the gospel; so what is the purpose of the word "integral" in the denial?
"Or primary to the mission of the church" - again, that word primary. What is the concern here? Something might be compulsory, essential, obligatory, required - and yet not be "primary". For example, I am obliged to all sorts of things, though my primary duty as a human being is to love God with all my being, and to love my neighbour as myself. What would it mean if I denied that all the things I'm required to do were "primary" - what is the importance of making this distinction? No doubt it has one, and that's not something I'm contradicting; but it's not explained. Is the church required to be conspicuous in good works? Are we intended to achieve this whilst avoiding that particular local churches should be conspicuous in particular good works? Is it being said that the church, as the church, officially and outwardly, must keep quiet about good works, but merely enable and encourage individual believers to perform them in a private capacity, so as to not cause misunderstanding about the church's "primary" mission? What is, and what isn't, being said here?
As noted above, what social and political activism are isn't defined, but, in the denials as in the affirmations, the emphasis in what is said falls upon improving the nation's legal code. Here, what comes immediately next, is "Though believers can and should utilize all lawful means that God has providentially established to have some effect on the laws of a society". That's an interesting flow/development of the statement; I wonder what the exact thinking is here? Are believers not meant also to utilise lawful means to alleviate the suffering of God's image-bearers, and to allow the love of God which is in their hearts by the Holy Spirit to be expressed to those in need? I do presume and believe that the authors of the statement think so.... but why is it not discussed?
The statement goes on to deny that the non-primary activity of attempting to change laws (as I say, I don't know why that is specially emphasised) is evidence of saving faith. Did anyone ever suggest otherwise? That sounds truly bizarre. Neither (the denial continues), does it constitute a "a central part of the church’s mission". Again, that word, "central". Does it constitute a required part of the mission? We're not told. This seems to be a non-denial denial. Are there really people who think that specifically changing laws is the central part of the church's mission? If there are, they must dwell a long, long, long way from the orbit of your average conservative evangelical church.
Does the church's duty, given by Christ, include good works? What can be affirmed or denied about that? How do those works related to the church's proclamation that Christ is Lord, and that in him God's love to the nations is declared? The statement appears to have nothing to say on this subject. It's not that I agree or disagree with it; it merely hasn't spoken.
Now I find that profoundly odd, and curious. I could, of course, do some more research. Presumably it was discussed at the time. I can't help noticing it, though. In fact, I looked through the statement specifically to see what it said about these questions, because it is an area I have concerns about. When outsiders say that evangelicals are far too concerned about laying down the strict confines of orthodoxy and it'd be great if they demonstrated more energy in condescending to help suffering people in their very messy, practical situations, it might well be because, ever since evangelicals made it a priority to clarify that they do not believe "the social gospel", we don't seem to have made it the same priority to so clearly, and conspicuously, make it clear that our lives are handed over to showing love to people in need. If something is not quite right with us, then would it not lead to statements like the above being written. Is it just me? Does it not strike you as odd that the statement has the ambiguities, and the omissions, that it does? Where does that come from, and how does that happen? Does the above statement strike you like paragraphs written by people who are busy getting their hands dirty, sleeves rolled up, sharing the love of Christ with people in deep need?
If we read the rest of the statement, the specific concerns of the authors in relation to society and culture in writing the statement are clearly to do with refuting sexual immorality, feminism, identity politics, "Black Lives Matter"-adjacent-type ideology (though remember this is 2018, not 2020). One line that repeats the ideas of section 8 is "And we emphatically deny that lectures on social issues (or activism aimed at reshaping the wider culture) are as vital to the life and health of the church as the preaching of the gospel and the exposition of Scripture." I again find myself wondering whether there has really been anyone of any note in, around or adjacent to Bible churches who has said that lectures on social issues are "as vital to the life and health of the church as the preaching of the gospel". But the next sentence is interesting: "Historically, such things tend to become distractions that inevitably lead to departures from the gospel." What are the "things" here? The only thing that seems to work grammatically is to say that it's the lectures and activism themselves, aiming to reshape the wider culture. i.e. They're positively dangerous. Does this only mean lectures/activism that are simply wrong (e.g. campaigning to redefine marriage) in themselves? Presumably not, since that's not a "distraction", that's just an evil. Evangelicals wouldn't speak of proclaiming false doctrine and denying God's creation order (things that are the concern of other parts of the statement) as merely a "distraction". The sentence comes in section 14, on racism. So does it mean that if the church speaks out or campaigns excessively about racism, then that is what tends to become a distraction and leads people away from the gospel? What in history is being referred to here? Must we actually, if we see actual (rather than pseudo-)racism prefer to keep quiet and do nothing because the defence of the gospel requires it? This sounds an extraordinary doctrine.... but it's outlined so briefly that it's really impossible to know.
Again, as I say, I could do more research and look more into this; as a statement from 2018, presumably there was debate about it at the time. For now, it's filed away in my head. But I must say that if this statement was intended to perform the normal function of such a statement, i.e. to clarify things and advance the state of understanding of one's position, by carefully distinguishing things that differ with accuracy and precision, so that the truth shines more brightly, then at least in the areas that I looked at it for, it badly failed.
