Why We Worship This Way: A Guide To the Liturgy of the PCA

Call to Worship

Many think worship begins when we decide to sing or pray. But in Scripture, worship begins with God calling His people to “come into His presence…” (Psalm 95:1-6; Psalm 100:1-5). God always speaks first! ​He draws near to us, gathers us, and invites us to receive His grace. History shows the earliest Christian gatherings beginning with such a divine summons. Continuing this pattern, we begin our services with a Call to Worship, encouraging the body of Christ to respond to His invitation with joy, humility, and hope.

Confession of Sin

The modern church leaves little room for the mention of sin during worship. But when we enter God’s presence, His holiness should invoke a response like the prophet Isaiah – “Woe is me … a man of unclean lips” (6:5). When Israel gathered “they stood and confessed their sins…” (Neh. 9:2). The church was commanded to do the same, both in scripture (Jas. 5:16) and in early church tradition (Didache 4:14, 14:1). Continuing this pattern, we confess our sins corporately, sincerely, and humbly – but also with hope, for the Lord is merciful and ready to forgive.

Assurance of Pardon

After confessing our sins, many are tempted to remain weighed down by guilt or wonder if God truly forgives. But Scripture declares that “if we confess our sins, he is faithful and just to forgive us…” (1 Jn. 1:9). In Christ, God does not merely overlook sin – He fully pardons all who repent and believe. From the 2nd-century rites of public reconciliation, through the Reformation’s corporate  assurance of pardon, ministers have always proclaimed God’s promises of forgiveness to comfort repentant sinners with the gospel. Continuing this pattern, we hear an Assurance of Pardon each Lord’s Day after our corporate confession of sin, resting in the joy and peace of Christ’s finished work.

Singing

Many people hesitate to sing in church because they feel shy, untalented, or think singing is only for the musically gifted. But Scripture commands the whole congregation to sing: “addressing one another in psalms and hymns and spiritual songs…” (Eph. 5:19). In worship, God calls every believer to lift their voice together. From Christ singing hymns with His disciples (Mt. 26:30), to the early church “singing a hymn to Christ as to a god” (per Pliny the Younger, c. AD 112), to the majestic Genevan Psalter, the church has always been a singing people. Continuing this pattern, we corporately sing the inspired Psalms, alongside faithful hymns and gospel-rich spiritual songs. We come ready, not merely to listen, but to join the saints in making a joyful noise to the Lord (Psa. 95:1).

Kingdom Prayer

Too often, corporate prayer can feel like a transition moment – something to fill time during stage transitions. But Scripture presents prayer as a central element of corporate worship. The church is urged to offer “supplications, prayers, intercessions, and thanksgivings… for all people” (1 Tim. 2:1-2). From the first Christians who “devoted themselves” to prayer (Acts 2:42), to the prayer forms preserved in the 2nd-century Didache, to the Reformation’s Book of Common Prayer, believers have always prayed together, seeking the spread of Christ’s kingdom and the will of God on earth (Matt. 6:9-10). Continuing this pattern, we join together in a Kingdom Prayer each Lord’s Day, praying with faith, trusting that God moves in power.

Confession of Faith

Many think doctrine is dry, divisive, or best left to pastors and scholars. But Scripture calls us to “hold fast our confession” of faith and proclaim it together, “teaching and admonishing one another” (Heb 4:14, Col. 3:16). From the earliest creeds embedded in the New Testament itself (like 1 Cor. 15:3–5), to the 4th-century Nicene creed, to the rich catechisms of the Reformation, Christians have publicly confessed the faith to guard sound doctrine, unite the church, and pass the truth on to the next generation. Continuing this pattern, we regularly confess our faith together using historic creeds and catechisms rooted in Scripture. We come ready, not only to declare what we believe, but to encourage and strengthen one another in the truth of the gospel.

Giving

Many today are suspicious of church giving, assuming churches are profit-driven. But Scripture presents giving as an act of worship and thanksgiving to God, not a fundraising scheme of man (2 Cor 9:7, Php 4:18). It instructs us to set aside our offerings “on the first day of every week” (1 Cor. 16:2), recognizing that all we have comes from Him. From the tithes and offerings of Israel through the weekly collections “within the Sunday assembly” (Justin Martyr, First Apology, 155 A.D.), God’s people have always supported the work of ministry and mercy through joyful generosity. Continuing this pattern, we present our tithes and offerings each Lord’s Day. We come ready to give cheerfully (2 Cor. 9:7), trusting the God who has first given so richly to us.

The Lord’s Supper

Many today view the Lord’s Supper as a purely symbolic memorial – meaningful, perhaps, but not important enough to celebrate often. But Scripture describes this meal as a “participation” in Christ (1 Cor. 10:16-17), commanded by our Lord for the strengthening of His people (Lk. 22:19-20). The first Christians devoted themselves regularly to “the breaking of bread” (Acts 2:46), and early writers like Justin Martyr testify to the church’s weekly celebration of the Lord’s Supper as a means of grace (First Apology, 155 A.D.). Following this pattern, we celebrate this sacrament each Lord’s Day. We come hungry to feed by faith upon Christ, the “true Bread from Heaven” (Jn. 6:32).

Scripture Reading

In a world of short attention spans, many expect only a few scattered Bible verses to support the preacher’s sermon topic. But God commands us to devote ourselves “to the public reading of Scripture,” for “faith comes from hearing, and hearing through the word of Christ” (1 Tim. 4:13; Rom. 10:17). From Joshua reading the Book of the Law “before all the assembly of Israel” (Josh. 8:35), to the early church gathering “on the day called Sunday” to read “the memoirs of the apostles and the writings of the prophets” (Justin Martyr, First Apology), to the Reformers’ restoration of consecutive Scripture reading in corporate worship, God’s people have always gathered to hear His Word publicly proclaimed. Continuing this pattern, we corporately read God’s Word together each Lord’s Day. We come ready not merely to hear the words of man, but to receive the living and abiding Word of God.

Children’s Sermon

Children are often viewed as distractions in worship or as too young to benefit from the teaching of God’s Word. But Jesus commands, “Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven.” (Matt. 19:14). Scripture repeatedly calls parents and the covenant community to teach God’s truth diligently to the next generation (Deut. 6:6-7; Eph. 6:4). Throughout church history, Christian worship has included the instruction of children as members of the visible covenant community. Continuing this pattern, we take time each Lord’s Day to speak directly to our children from God’s Word. Our children come ready to learn, and our church family comes ready to encourage them in the faith.

Sermon

Many today see preaching as little more than a motivational talk or practical self-help message delivered by a dynamic public speaker. But Scripture describes preaching not as “enticing words of man’s wisdom” (1 Cor. 2:4), but as the proclamation of the Word of God (2 Tim. 4:2), centered on “Christ crucified” (1 Cor. 1:23). From Peter preaching Christ to the crowds at Pentecost, to the Reformers’ recovery of expository preaching, God has always advanced His church through the faithful preaching of His Word. Continuing this pattern, we devote ourselves to the preaching of God’s Word each Lord’s Day. We come ready not merely to hear from man, but to hear and respond to the voice of God in Scripture.

Benediction

Many people think the closing of a worship service is simply housekeeping – a final prayer, a few announcements, and a dismissal to head home. But in Scripture, God sends His people out with a spoken blessing: “The Lord bless you and keep you…” (Num. 6:24). A benediction is not merely a wish for good things, but God’s Word of blessing pronounced over His covenant people as they go back into the world. From Aaron’s blessing declared over Israel, to the closing words of grace and peace in the epistles, to the benediction in Calvin’s Genevan liturgy, God’s people have long departed worship under His declared favor. Continuing this pattern, we end our services with a benediction. We depart with joy, peace, and God’s blessing.
