Here is an interesting and very old quote about the church. All I know about this quote is that it was supposedly written or spoken by William Law (1686-1761). Please let me know if you know something more about this.
It is very observable that there is not one command in all the Gospel for public worship; and perhaps it is a duty that is least insisted upon in Scripture of any other. The frequent attendance as it is never so much as mentioned in all the New Testament, whereas that religion or devotion which is to govern the ordinary actions of our life is to be found in almost every verse of Scripture. Our blessed Savior and His Apostles are wholly taken up in doctrines that relate to common life.
Update: Apparently this quote is from chapter 1 of A Serious Call To A Devout And Holy Life written by William Law in 1728. I am not familiar with this book, but I may try to read some of it, since it is online.
