Salvation has something to say not only to the individual man but also to the culture. Christianity is individual in the sense that each man must be born again, one at a time. But it is not individualistic. The distinction is important. As God made man, He also made an Eve so that there could be finite, horizontal relationships between two people. Death in the City (Downers Grove, InterVarsity Press: 1969) 86

The communion of the saints means, not a series of loosely related cliques, but an all-embracing and self-abnegating fellowship.

One hundred religious persons knit into a unity by careful organization do no constitute a church any more than eleven dead men make a football team. The first requisite is life, always.

Has it ever occurred to you that one hundred pianos all tuned to the same fork are automatically tuned to each other? They are of one accord by being tuned, not to each other, but to another standard to which each one must individually bow. So one hundred worshippers meeting together, each one looking away to Christ, are in heart nearer to each other than they could possibly be were they to become "unity" conscious and turn their eyes away from God to strive for closer fellowship. Social religion is perfected when private religion is purified.
