I hope you're not suggesting that this is what I'm suggesting.
If I may explain, the fact is that there are more people who need to be ministered to by the gospel than the current number of good gospel-preaching churches today. I live in San Diego and attend a PCA church. It is a large, metropolitan area which needs good churches throughout the area.
Our strategy is to plant as many churches in the area as possible. We don't want to set up one big church downtown and have everyone commute to it, as is the mega-church model. Many churches within the surrounding neighborhoods is a better way to reach people for the gospel. It is NOT about, as I think you are suggesting, giving people what they want. It is NOT a seeker-sensitive model.
So far, our church has planted eight locations in the county, but our church recognizes that the PCA does not have enough resources to effectively reach all of San Diego county. Therefore, we support and partner with other like-minded gospel-centered churches that are not in the PCA.
Others may think that having one perfectly WCF-complaint, exclusive-Psalter church in a major city is enough for God's word to reach people, but I don't think so.
No, that's not what I'm suggesting, I was just using the example to make a couple of points. First, although the model I was suggesting might be successful, it presupposes that issues like polity, worship, and doctrine are more the result of tradition and preference than anything else, and that it doesn't really matter what we practice in regards to these things, as long as the gospel is being preached. It presumes that the Bible doesn't teach things about them and that God doesn't really care much about them at all. They may be important to us, but they aren't important to Him. If I believed that, I'd cease to be a Presbyterian immediately, because I'm not Presbyterian because I was born into it, or I happen to like it's traditions. I'm a Presbyterian because of my conviction that it is the best expression of the theology taught in the Bible - and yeah as irritating as we are to the world I'm a Puritan, not a Latitudinarian, when it comes to theology.
As it so happens, I believe many Pentecostal and even Anglican churches preach the gospel, but I also believe that their worship is unbiblical and produces a harvest of bad fruit. Frankly I don't want to use the resources that the Lord provides to us to teach people Dispensationalism, Arminianism, Pentecostalism , and so on, even if a gospel presentation is tacked on. I don't want to have started churches where there are no elders, or where the Minister is appointed by a Bishop, or where there is no Confessional statement by which the Minister is held accountable, or a constitution that protects the rights of members and provides them the ability to receive a fair trial and even an appeal. I don't want to start a church whose governing body has no higher court keeping them accountable via review and control, and so on.
To put it quite simply, if I were able to plant churches of any stripe, I would be forced to say that the 2000 Puritan ministers who chose to be kicked out of the Ministry in 1662 because of their refusal to accept the Act of Uniformity were wrong, and I don't, or that Jenny Gedes should have bit her tongue and stayed on her stool. They said that things like church government, worship, Christian liberty and so on are not things we should compromise on in order to see that the gospel gets preached.
Now before someone misunderstands me, I have had wonderful fellowship with more Pentecostal, Baptists, Independent Fundamentalists etc. brothers and sisters in Christ than I can count, and I'm sure I'll see them in heaven, but while there is much we agree on, I have no desire to spread abroad their theological distinctives, some of which, I consider downright dangerous (Pentecostalism in particular). And lets face it, how could I in all seriousness say that I subscribed to the idea that as WCF 28.5 says "Although it be a great sin to contemn or neglect this ordinance" and then plant churches that do exactly that.
Now I'm not saying I want just one Presbyterian church in every city, I'd like to see many planted. I want to see as many solid OSP churches planted as we can.
I am very late on this thread but I appreciate this post. I feel the same way about Reformed Baptist churches, but I appreciate your willingness to stand for doctrine and praxis.
