I’m going to say something that is at once the most obvious and most neglected truth about the

purpose of the church out there today; namely, that you cannot decide what the church ought to be
doing until there is fundamental clarity about what the church
is. But in my observation, there is anything but “clarity” about the purpose of the church. Everywhere you turn, in every book you read, someone is offering a new “bag of tricks” to save the church from extinction in a postmodern, post-Christian world. [I wish I had a nickel for every time over the past 2,000 years someone proclaimed the church “extinct!”] When you actually analyze them, however, they fall into two categories.
The first is what I would call “Church as the Vanguard of the Consumer Culture.” The mottos of the consumer culture are well known: “The customer’s always right” and “He who dies with the most toys wins.” Perhaps the best I’ve heard is the Chase Bank Card commercial in which a man lusts for a new flat-panel television and goes to a big box store to shop for one. It is not accidental that as he shops for his television in the big box store, the venue has a “sanctuary” feel about it, and a choir swells in the background with anthem-like strains: “I want it all; I want it all; I want it all; I want it now!” In such a consumer culture, some in the church have “gotten it” and have adapted their mission and strategy to the culture and its values and have re-invented “church” as sort of a “pious Wal-Mart” competing with the big box “superstore” down the street and giving the customer whatever the customer wants to keep him happy and attending. It actually can get kind of silly - if the customer wants a “low-impact aerobic worship service,” then of course we have to start one.
The second is what I call “Church as Harbinger of Human Hubris.” This is the idea that man, individually or collectively, has within his own resources the power to “fix” the world and turn it into the kingdom of heaven here and now. This is church as “Social Service Organization.” If we can just get people to cooperate and work together and vote the right way, we can bring about the kingdom of heaven right here, right now.
The problem with both of these approaches is that they deny the fundamentally
eschatological (read “other worldly”) character of the church as described by Jesus in the gospels; namely, that the church is not here to pander to the world on the one hand, or to “fix” it on the other. The church is rather the Vanguard of the Kingdom of God,
in the world, but not
of it. That is to say, the church of Jesus Christ is a community of people who’ve caught sight of and been captured by a vision of
another world he called “the kingdom of God,” a world that is not only different from this world in vision and values, but is in almost every way that matters
competitive with it (see John 17:14-16).
Now, of course, those who argue for the purpose of the church as capitulating to the culture will criticize this perspective as being too “escapist” and “other worldly,” but that criticism is bogus. Until either death or Christ’s return takes us out of this world, we’re
in the world; there is no “escaping” it. The question is not whether the church will be “in the world” or “out of the world;” the question is whether the church will be
the church “in the world,” or will it instead be some “knock off” masquerading as the church of Jesus Christ.
And so, if Jesus is to be our guide as to the nature and character of his church, then its purpose is clear: “Go into the world and
make disciples by baptizing them and teaching them,” is how he put it (Matt. 28:19-20). That the church has an essentially
eschatological character is seen in the promise that follows the purpose: “And I will be with you always,
even to the end of the age.”
But how do we get that kind of church in this kind of culture? It starts I think with pastors who are more motivated by a
biblical vision of church than the latest church growth gimmick or mandate from whatever ecclesiocracy they happen to serve. It takes courage these days to stand before a congregation and say: “We’re in the disciple-making business, and that’s measured more by lives changed and disciplines owned and values embraced than by buildings built or bucks banked or heads counted.” A retired pastor friend who speaks with both perspective and passion about the church says that the biggest challenge facing the church today is what he calls “undiscipled disciples,” people who
think they're disciples because they go to church or small group, but whose lives evince none of the
disciplines (intellectual, emotional, ethical, spiritual, financial, volitional) characteristic of a disciple of Jesus Christ. They are folk who have been “inoculated” with just enough Christianity to keep them from “taking” the real thing. But if you’re only interested in the short run, that’ll do! It takes tremendous courage for a pastor to plant his life in the middle of a congregation and say: “I won’t let you off; I won’t let you go until all of us attain the ‘measure of the stature of the fullness of Christ.’” If you don’t have a pastor like that, get one!
