[DIGEST: What we have now as chapter 47 was not part of either the Proposed Book of Church Order (1973) or the Book of Church Order as adopted by the first General Assembly later that same year. Rather, this chapter, with its nine paragraphs, dates to 1975 when this text was presented by the Constitutional Documents Committee, as part of its proposed revision of the Directory. [M3GA, 3-15, pp. 55-56] This chapter, originally numbered as chapter 48, presents entirely new text not previously part of any prior Presbyterian Book of Church Order. The chapter was renumbered as chapter 47 when the original chapters 8 and 9 were merged in 1980. No changes to paragraph 47-3 have been made since adoption in 1975, other than the editorial addition of the Scripture reference at the end of the verse.

ANTECEDENT TEXTS:
1975, 48-3, [M14GA, p. 339]
The end of public worship is the glory of God. His people should engage in all its several parts with an eye single to His glory. Public worship has as its aim the building of Christ’s Church by the perfecting of the saints and the addition to its membership of such as are being saved — all to the glory of God. Through public worship on the Lord’s day Christians should learn to serve God all the days of the week in their every activity, remembering, whether they eat or drink, or whatever they do, to do all to the glory of God.

COMMENTARY:
Morton H. Smith, Commentary on the Book of Church Order, 6th edition, 2007, p. 397.
The first part of this paragraph speaks of the end or goal of public worship. It must always be "the glory of God." All too often this goal is lost. The modern church has too often made the goal of the worship service evangelism or instruction of the believers, without keeping central the idea of glorifying God. On the basis of the book of Acts, the addition of those who are being saved is a result of worship, so also is the edification of those who have been saved. The idea of being entertained is foreign to the Biblical concept of worship. It
should be observed, that though a congregation participating in true godly worship has the experience of Christian fellowship, this is not named in the paragraph as one of the aims of worship. This is a byproduct
of worship, not its goal.
The last sentence indicates one of the benefits of worship on the Lord's day. It is the fact that the Christian becomes informed as to how he is to live all of his days to the glory of God. Some have suggested that everything that the Christian does is to be done as an act of worship. This sentence suggests better language regarding the everyday activity of the Christian. It is the Biblical language of doing all to the glory of God. The term "worship" is restricted to the direct meeting with God, either in public or private acts of worship. To use the term "worship" universally of all acts of service to God, makes the idea of a regulative principle for worship meaningless.
