should church fit in with society or?

the following is summarised from and prompted by nick baines' post, and comments on it, about the wrong question

others often struggle with the question of how christianity is struggling for survival in modern society, especially with fewer people attending church.

and often express the idea that the solution is to leave behind the institution of the church.

but this approach seems to ignore a history of which the church should be proud in terms of what it  has already inspired others to in terms of - for example -  art, music or championing the cause of the weak or poor

nor indeed the tremendous contribution the church makes to local communities up and down the land in terms of continued service, facilities, clubs and hours of voluntary work 

all undergirded by a desire to help people connect with the good news that is jesus
