Elements of Worship
Section 5 sets forth the ordinary elements of public worship: reading of Scripture (having its own importance in worship apart from preaching); preaching and hearing the Word; singing of psalms; administration of the sacraments of baptism and the Lord's supper. To understand in more detail what the Assembly believed about each of these, see the Directory for Publick Worship.
The Assembly advocated the exclusive use of the biblical Psalms in praise. With this as the only approved manual for praise, the assembly produced a metrical Psalter containing only the 150 Psalms. The Assembly's Psalter was later revised in Scotland and became the Scottish Psalter of 1650.
