Rudiment #3: Content of the Worship Service

This point is particularly addressed to ministers and ruling elders in the church—but it is also good for all the faithful laity, too.

The divine worship service, held on the Lord’s Day (Sunday), by the church, called by the elders, and under the authority of the Word of God, ought to include the following elements, (though not all, necessarily, in every service):

A Call to Worship (from the Bible—usually from the Psalms).*
An Invocation, (where God’s special covenantal presence is implored).*
The singing of hymns and psalms.*
The reading of the Holy Scriptures, (both from the Old Testament, and the New).*
Some kind of Confessional statement, (either a Creed, or the Westminster Confession [for example]).
Corporate Covenant Prayer (where often there is confession of sin, and the giving and receiving of absolution, [viz. assurance of pardon—to the true saints]).*
An Offering, where the believers worship God through the giving of their tithes and offerings.
The Preaching of the Sermon.*
The Administration of the Sacraments: Baptism and the Lord’s Supper.
The taking of Covenant (church membership), and Office (elder and deacon) Vows.
And the proclamation of the Benediction.*

These practices are all found in the Word of God; and the desire to limit the church’s worship to the Bible’s instruction (a practice referred to as the “Regulative Principle”), is healthy and good. This aids in deterring “entertainment,” and man-centered activities.

PS: Those points denoted with an asterisk ("*"), *should* be found in every Lord's Day worship service.
