It seems to me that the core problem is less with “the organized churches” than with “the Christianity.” It would send a rather strange message to say, “We’re taking our religion to the streets because it hasn’t worked very well in the churches.”
At least in America, the churches always mirror the secular society around them. Long before the present time, we have had pretty much the same situation Kierkegaard was complaining about in the Denmark of his day and Tolstoy was complaining about in the Russia of his – a cheap, superficial “Christianity” that really isn’t Christianity at all, but rather just a branch of the secular society that conforms and blends in as nicely as any other branch.
Since the secular society has pretty much reached the Last Days stage that 2 Timothy 3:1-5 describes, I see no reason to be optimistic “Christianity” will likewise not continue “having a form of godliness, but denying the power thereof.”
I’ve often said that if I were advising atheists, I think the single strongest argument against Christianity would be: “You say that only you have the transforming power of the Holy Spirit. Why is there not more evidence of this – in your individual lives, in your churches and denominations, in your religion as a whole?”
Is there truly anything that distinguishes “Christians” from Buddhists, Hindus, Atheists and New Agers except in their own self-congratulatory minds? Where is the evidence of a Holy Spirit within Christendom that is any different from the “transforming power” of Buddhism, Hinduism, Humanism or any other religious or moral system?
The fact that these are at least legitimate questions without easy answers ought to be very troubling. Is there something radically, fundamentally wrong with our “Christianity”? This to me seems the more pertinent question.
“And do not be conformed to this world, ....” Romans 12:2 (NASB). “’I have given them Your word; and the world has hated them, because they are not of the world, even as I am not of the world. I do not ask You to take them out of the world, but to keep them from the evil one. They are not of the world, even as I am not of the world.’” John 17:14-16 (NASB).
It seems to me that “Christianity” is about as “of the world” as it could get. “Christianity” is marketed the same way Apple markets iPhones and McDonald’s markets hamburgers, and the results are measured the same way. "Christianity" attempts to conform itself to the world to the maximum extent possible.
The Christianity that Jesus was talking about would be observably different from the society around it. It would be hated by many because it stood in opposition to the society around it, not for the superficial reasons it is hated today. It would be appealing to those with ears to hear precisely because it was different. It would inevitably be smaller, at least for a long time, than “Christianity.”
So I don’t see abandoning the organized churches, or taking Christianity to the streets, or reforming Christianity in any other way as being productive until you have confronted the core question, “What is wrong with ‘Christianity’ and why is any random group of 500 ‘Christians’ pretty much indistinguishable from any random group of 500 Buddhists, Hindus, Atheists or New Agers in terms of the fruits described in Galatians 5:22-23, good deeds, successful marriages, miracles, scandals or any other measure that really matters?” An atheist would say, "Because Christianity isn't real." I don’t have all the answers, but as a Christian my guess would be, “Because ‘Christianity’ hasn’t tapped into the power of the Holy Spirit at all” (which brings to mind Chesterton's famous quip that "Christianity has not been tried and found wanting; it has been found difficult and not tried").
Thus ends the Sunday sermon of Pastor Runner of The Church of What Runner Believes, which is the only one I've attended for many years. (I did visit my wife's Baptist church in Minsk, Belarus, a Soviet-style dictatorship where the Orthodox church is the only officially tolerated one. You do not attend a Baptist church in Minsk for any reason other than a sincere belief in the Gospel; attendance is going to put you at odds with your government and the society around you and is not going to benefit your secular life in any way. I truly felt as though I was in a Christian church for the first time in my wife. My wife's pastor, who had been to America, urged her not to come here because the "Christianity" she would encounter would not be the Christianity she had known.)
