Singing & Teaching in Worship

May 2026 | J.A.O. Vergara

When studying the history of Christian worship, one must begin by conceding a well-documented historical fact: in the literal context of the first-century New Testament church, instrumental music is never explicitly mentioned in their gatherings. The early church, by all reliable historical accounts, sang a cappella.

For centuries, this historical reality has fueled a fierce theological debate regarding how modern Christians should sing in worship. Should churches strictly mandate unaccompanied vocal singing, or is there freedom to use mechanical instruments?

To answer this, one must look beyond the mere presence or absence of instruments and examine the method of interpretation being used. The divide ultimately comes down to how a person views the New Testament: Is it a book of detailed legal blueprints for a church service, or is it a framework of grace that gives believers freedom to express their praise culturally, provided it is orderly and edifying?

This friction becomes incredibly apparent when we examine the ten verses most commonly cited to support a strict a cappella mandate.

The Assembly Verses and the "Preaching Paradox"

Often, ten specific New Testament verses are grouped together to prove a rule for Sunday morning Assembly (Greek: ἐκκλησία, ekklesia — a gathered congregation) singing. However, of these commonly cited texts, only four actually refer to the gathered Assembly singing of the church: 1 Corinthians 14:15, Hebrews 2:12, Ephesians 5:19, and Colossians 3:16.

Before diving into the primary proof-texts of Ephesians and Colossians, it is important to briefly look at the first two:

Those who view the New Testament as a legal blueprint, however, lean most heavily on Ephesians 5 and Colossians 3, arguing that because Apostle Paul specifically commanded "singing" (Greek: ᾄδοντες, adontes — to use the voice in song), any other medium (like playing an instrument) is excluded.

However, applying this strict, exclusive blueprint reading creates a massive logical hurdle regarding teaching. Let us look closely at the phrasing:

If we argue that these verses are highly restrictive, exclusive laws meant to regulate exactly what mediums are allowed in a church service, then we must apply that restriction consistently. The text explicitly states that the medium for speaking, teaching, and admonishing is "psalms (Greek: ψαλμός, psalmos / Hebrew: מִזְמוֹר, mizmor — a melody historically sung to instrumental accompaniment), hymns (Greek: ὕμνος, hymnos — a sacred song of praise), and spiritual songs (Greek: ᾠδὴ πνευματική, ode pneumatike — a song pertaining to the breath or Spirit)."

If these verses strictly outlaw playing instruments because playing is not explicitly mentioned, then they logically outlaw spoken sermons and spoken teaching as well. Under a strict blueprint reading, it is a violation for a preacher or congregation to teach, speak, or admonish in any form other than through song.

Some defenders of the blueprint view might attempt to avoid this trap by arguing that the grammar in Colossians 3:16 separates the actions—claiming that "teaching" is one distinct command and "singing" is a separate one. However, this defense collapses when measured against the overwhelming consistency of the rest of Scripture, particularly Ephesians 5:19. In Ephesians, the grammar offers no such separation: "speaking to one another in psalms and hymns and spiritual songs." The action of speaking is inextricably tied to the musical medium. The paradox remains intact.

Furthermore, by these exact same strict standards, believers would be logically prohibited from singing any songs with lyrics not explicitly written in Scripture. If the blueprint law strictly limits acceptable worship materials, then composing uninspired human lyrics, adding extra words, or even paraphrasing Bible verses to fit a musical meter would constitute an unauthorized "addition" to the set standard.

Because practically no Christian tradition actually enforces this—recognizing that spoken preaching and human-composed hymns are obviously allowed and encouraged—it reveals a deep inconsistency. It proves that treating these specific verses as a rigid, restrictive legal code forces an unnatural rigidity onto the text.

NT verses on singing do not all point to Assembly singing

While the four verses above address the gathered church, a close look at the actual historical contexts of the remaining verses reveals that they have absolutely nothing to do with a gathered church service.

Using these specific verses to mandate a strict a cappella rule for the gathered church is theologically flawed for several reasons:

When a theological interpretation requires inventing loopholes—like separating "secular joy" from "sacred joy"—just to permit believers to attend a wedding or sing in the car without violating James 5:13, the interpretation itself poses more questions and triggers confusions.

The Psallo Debate and the Instrument of the Heart

Another crucial piece of the assembly debate centers around the Greek word psallo (ψάλλω), used in Ephesians 5:19 (translated as "making melody"). Historically, in classical Greek, psallo explicitly meant to pluck or twang the string of a musical instrument, such as a harp or lyre. However, proponents of strict a cappella worship often point out that by the first century, in Koine Greek, the word had evolved to simply mean "to sing."

Those who argue for strict a cappella worship also correctly point out a profound theological shift in the New Testament: the physical temple of the Old Covenant has been replaced. Believers themselves are now the temple of the Holy Spirit. Therefore, we cannot deny that the physical instruments of the Old Testament temple have been replaced by a new, spiritual instrument. Apostle Paul explicitly identifies this instrument in the verse itself: we are to make melody "in your heart" (Greek: καρδία, kardia — the center of spiritual and physical life).

This is a beautiful and entirely scriptural truth. The human heart is indeed the primary and essential instrument of New Testament worship. However, we must recognize that identifying the heart as the primary spiritual instrument—and even accepting the Koine Greek definition of psallo as purely vocal singing—does not logically necessitate a ban on physical accompaniment.

Just as a command to "preach from the heart" does not forbid the use of a microphone to amplify the voice, the command to "make melody in your heart" does not inherently forbid the use of a physical instrument to accompany the voice.

Some strict a cappella defenders understandably attempt to separate these through the theological framework of "expedients versus additions." They argue that a pitch pipe, a microphone, or a hymnal is merely an expedient—a lawful tool used to carry out the specific command to sing. Conversely, they argue that plucking a guitar or playing a piano is a separate physical act involving the hands, making it an unauthorized addition to the command to sing.

However, if we strictly apply this logic—that any separate physical act used to aid the music is an unauthorized addition—the argument destroys itself. By this standard, the church must immediately ban the pitch pipe and the hymn book. Blowing into a mechanical pitch pipe to establish a key is a separate, physical act using a mechanical device to produce an artificial musical note. Holding a hymn book, turning pages, and reading human-arranged four-part harmony (SATB) from a printed page are separate physical acts and cognitive additions never explicitly commanded in the New Testament.

Furthermore, the "addition" argument mischaracterizes how the instrument is actually functioning in the gathering. Even if we fully accept and respect the Koine Greek application of psallo as specifically meaning "to sing," using an instrument to accompany that singing does not mean the entire congregation is now commanded to play an instrument. Not everyone in the assembly is playing; only those who are leading the music are. The congregation itself is still fully executing the biblical command to sing. The instrumentalist is functioning in a leadership capacity, utilizing a mechanical tool for the express purpose of assisting all members to sing in tune and in unison.

Consider the universally accepted practice of a song leader directing the congregation with hand motions. The leader waves their hands to establish the tempo—sending visual waves through the air to synchronize the believers based on the rhythm already playing in their heart. If that same leader, knowing the tune by heart, uses a guitar or piano to establish that exact same rhythm and melody, they are simply sending a sound wave instead of a purely visual one. Both actions serve the exact same subordinate purpose: aiding believers to sing in sync and unison.

In this sense, an acoustic instrument functions exactly like the microphone. A microphone merely amplifies the voice of the person leading; if the leader sings off-key, the microphone amplifies the error. Similarly, if an instrumentalist does not know the tune, the guitar or piano simply amplifies their mistake. Therefore, all non-living mechanical devices—whether microphones, pitch pipes, or pianos—are mere amplifiers. They cannot produce worship on their own. They are not the "true instrument" of praise; they merely amplify and transmit the true music that is already being played on the strings of the human heart.

If a mechanical pitch pipe, a printed hymnal, or a waving hand can be justified as mere "subordinate aids" to help the congregation sing in tune and unison, then logically and hermeneutically, an acoustic guitar or piano functioning to keep the congregation in key and rhythm falls into the exact same category of an expedient, subordinate tool. If a believer plays a physical instrument but their heart is not engaged, it is nothing more than a noisy gong or a clanging cymbal (1 Corinthians 13:1). But if the strings of the heart are truly being plucked in devotion to Christ, the addition of an acoustic guitar or piano to aid the assembly does not negate the spiritual reality happening within. The physical tool does not invalidate the spiritual posture; it merely accompanies it.

The "Strange Fire" Defense

Another frequent objection raised against the use of instruments is the sobering Old Testament account of Nadab and Abihu (Leviticus 10). These two priests were struck down by God for offering "unauthorized" or "strange fire" before the Lord. Many strict a cappella advocates point to this passage—a concept often echoed in broader theological discussions regarding unauthorized worship, such as John MacArthur's book Strange Fire—to argue that God strictly regulates worship by silence. They claim that because God commanded singing, playing an instrument is an unauthorized addition, equivalent to offering "strange fire."

We must absolutely recognize the severity of Nadab and Abihu's actions. Treating God’s holy directives with a careless attitude is a dangerous thing. However, if we are going to apply this strict, Levitical standard of "unauthorized fire" to the New Testament church's worship, we must apply it equally and consistently.

If an entire congregation stopped singing entirely and instead only played mechanical instruments—completely replacing the human voice—one could reasonably argue they have abandoned the biblical command to sing. Replacing God's design would indeed parallel the error of substituting authorized fire with strange fire. But that is not what is happening when an instrument is used as a subordinate tool to accompany and guide the congregation's vocal praise.

Furthermore, if the "strange fire" standard dictates that any medium not explicitly mentioned in Ephesians 5:19 and Colossians 3:16 is a severe violation, then the strict blueprint logic circles back to create an unintended paradox for our brothers and sisters who hold this view. Because the texts explicitly command teaching and admonishing through psalms, hymns, and spiritual songs, a preacher who stands up and delivers a spoken, non-sung sermon would be guilty of offering "strange fire." The severe applicability of Nadab and Abihu's error falls equally upon the non-singing preacher as it would on a non-singing congregation. Using the terrifying judgment of Leviticus 10 to ban a subordinate musical instrument, while completely ignoring it to permit a spoken sermon, reveals a deeply inconsistent and selectively applied theology.

The Myth of the "Secular vs. Sacred" Divide

When confronted with the logical extreme of applying the blueprint reading to James 5:13 (which would effectively ban instrumental music at weddings, birthdays, or in the car), a common theological loophole is introduced: the separation of "secular joy" from "sacred joy." Proponents will argue that James 5:13 only applies to official "worship," allowing believers to enjoy instrumental music in the "secular" parts of their lives.

However, this loophole is deeply problematic and entirely unscriptural. Nowhere in the Bible are God's people given two distinct identities—a secular life versus a sacred life. To a Christian, all of life belongs to God. This truth is explicitly stated in two powerful verses:

These verses dismantle the "secular joy" excuse. Apostle Paul explicitly states that whatsoever a believer does—even mundane things like eating and drinking—must be done for the glory of God and in the name of Jesus. Therefore, a Christian does not possess a "secular" identity.

If a person believes James 5:13 is a strict, exclusive law that bans instruments when expressing joy, they cannot use a "secular event" excuse to bypass it. Because every moment of a Christian's life is sacred and lived unto God, the strict blueprint reading logically demands a total ban on all instrumental music in all areas of life. Since enforcing a total ban on all instrumental music in daily life is clearly not the intent of the New Testament, it proves the initial interpretation of James 5:13—treating it as a rigid regulatory law—was flawed from the start.

The "Framework of Grace" View

The alternative approach reads the New Testament not as a modernized book of Leviticus detailing the exact step-by-step rules of temple rituals, but as a framework of grace.

Under this view, Apostle Paul’s letters to Ephesus and Colossae are pastoral encouragements highlighting that singing is a profoundly effective, community-building way to let the word of Christ dwell in a congregation. He is emphasizing the vocal and communal nature of the teaching, but he is not drafting a regulatory boundary designed to ban acoustic accompaniment.

This framework recognizes that while the first-century church did not use instruments, their reasons were largely circumstantial. Early Christians were poor, frequently persecuted, met secretly in small homes, and sought to distance themselves from pagan Roman theater. Their silence on instruments reflected their historical reality, not an eternal theological prohibition.

Furthermore, the Psalms—the very songs Apostle Paul commands the church to sing in these verses—are bursting with explicit commands to praise God with stringed instruments, trumpets, and cymbals (Psalm 150). It is highly unlikely that the New Testament writers intended to legally ban the very instruments celebrated in the songbook they were commanding the church to sing.

Additionally, the Book of Revelation explicitly describes heavenly worship as including "harps" (Revelation 5:8, 14:2). If the eternal, perfected throne room of God echoes with the sound of stringed instruments, it strongly reinforces the conviction that a strict earthly ban on those same instruments is theologically unsound. Why would God strictly forbid on earth what He explicitly includes in heaven?

Conclusion

The debate over instrumental music in worship is, at its core, a debate about the nature of the New Covenant.

If the New Testament is a rigid legal blueprint, then verses like James 5:13 criminalize a guitar string in joyous moments, and Colossians 3:16 accidentally criminalizes the spoken sermon on a Sunday. But if the New Testament is a framework of grace, the lack of instruments in the first-century church is a biblical historical account that must be kept as a reminder and encouragement of how worthy God is to be worshipped.

Ultimately, whether there was a specific prohibition or promotion of mechanical instruments in the biblical times of the New Testament, it does not bear the weight of a fundamental, fellowship-breaking issue. We must remember the wisdom of Apostle James and the first Council of Jerusalem (Acts 15), who determined not to burden the Gentile believers with rigid, unnecessary laws. Elevating the circumstantial absence of instruments into a strict, exclusionary mandate places an unwarranted legalistic burden on the church today.

God’s primary concern has always been the condition of the worshipper's heart. Whether singing a cappella or with mechanical aid, whether engaging in gathered Assembly singing or private praise, or even while navigating the mundane moments of everyday life, the true biblical mandate is a heart postured toward the Creator. If a Christian does not have a heart that glorifies God in whatever and whenever they are doing, that is the true and direct violation of Scripture.

On a personal level, I deeply cherish a cappella singing. When pouring out my heart in the presence of God, I often prefer the raw, unhindered sound of the human voice, allowing no mechanical means to distract me. There are times I set down all instruments to ensure I am playing nothing other than my own heart. In my deepest moments of communion with God, I naturally shut out the noise of the outside world; the clamor of my workplace cannot invade my prayer, and at home, my family sometimes has to physically touch me to get my attention.

Yet, despite my profound personal love for undistracted vocal praise, I recognize the pastoral grace of instruments. When I refer to "babies in the faith," it is not to separate levels of spiritual maturity, but rather to emphasize the loving accountability of leadership. When newly born-again brothers and sisters are not yet able to follow the tune of church music, the leaders take on the responsibility of helping them learn the songs as soon as possible. I will gladly use an instrument as a pastoral tool to guide them. Ultimately, my goal is not to primarily promote the use of mechanical aids, but I am firmly against a total ban on them—whether in Assembly singing or in ordinary daily living. At the same time, this freedom must be stewarded carefully. If needs be, I would readily admonish any brother or sister who plays instruments in a manner that causes disorder within the assembly, or whose act of playing fails to glorify God at all. The grace of the New Covenant provides the freedom to express praise culturally and musically, so long as it remains orderly, edifying, and—above all—done in ways that gives Glory to God and for God alone.

I recognize that the thoughts shared in this essay may cause internal wrestling or discomfort for some readers, especially for the dear brothers and sisters in Christ whom I hold close, but who hold a different perspective than my own. It is never my intention to cause distress or offense. My sincere hope and prayer is that these reflections will not become a reason for division, severed fellowship, or what the world calls "cancelation," but rather an open door for a gentle, loving discussion when time permits. We are bound together by the blood of Christ, which is infinitely stronger than our disagreements over the mechanics of worship.
