Before I write anything else here, I want to familiarize (or re-familiarize) you with the term, a cappella. Just check out Webster's at m-w.com for the definition. We know in secular use it means vocal music without instrumental accompaniment, but it's originally a Latin term meaning, "in chapel style," or as the title of this post suggests, "church style." Now why would vocal only music be called church style?
Well, looking around at common practice in churches of today, it doesn't make any sense, but if you dip into church history you'll find out that church music was strictly vocal-only until well into the Middle Ages. Even then its introduction into Catholic Churches was a matter of great contention. When the Protestant Reformation began, the leaders quickly repudiated any kind of music other than the human voice in church, and this stance persisted throughout protestant denominations until the 19th Century. Again, it found its way into Protestantism with a great deal of controversy and division.
The vast majority of Churches of Christ do not allow any kind of music in worship other than the human voice. Why? I'll give you three reasons, and let you decide where you stand.
First, I see nothing in the Scriptures to lead me to believe God (now) wants instrumental music in worship. In key passages like Ephesians 5, and Colossians 3, there is only mention of singing. In disagreement, some immediately point to Psalm 150, and other passages relating to the animal-sacrificial worship system of pre-Christian Israel. I believe in the authority of the Old Testament (OT) Scriptures, but only as fulfilled and properly interpreted through Christ (Colossians 2:17). While its principles about worship are eternal and fully applicable to Christian life, its precepts, especially regarding Tabernacle and Temple worship are not (Ephesians 2:14-15; Hebrews 10:1-10). Without going into sermon-like or scholarly detail, the instrumental music in worship passages in the OT fall under this category, and do not authorize the use of instruments in Christian churches. Folks make several other arguments related to Ephesians 5 and Revelation, but it's not my purpose to delve into these in detail in this "short" post.
Second, instrumental music (IM) in worship is less purely spiritual that a cappella, and is less inclusive, or unified as far as joint-participation in worship is concerned. I say it's less purely spiritual, because it employs sounds that don't edify the hearers, but rather serve to stir them up emotionally, or entertain them. As such it borders on self-worship in that it makes the worship experience more about what suits my senses than about what pleases God and teaches my fellow man (Ephesians 5:19; Colossians 3:16; consider also portions of 1Corinthains 14). I say it is less inclusive in that it unnecessarily singles out those with "special" talents and exalts them in the worship. There are even those in Protestant churches long known to use IM who have recently been shifting away from it for these, and other, more significant reasons, and several groups, other than churches of Christ have never used them (see this article).
Finally, the term a cappella means "church style" for a reason. It was so well known and accepted that Christian worship in song was vocal-only that the ancients named the style of music after it. The early church under apostolic guidance, and during the centuries closest to the lifetimes of the apostles rejected instrumental music in worship. It wasn't that they just happened not to use instruments, or that they couldn't afford to. Do some homework in the writings of the Early Church Fathers before Nicaea and you'll see they actually opposed the use of them. For whatever the reason, if the apostles and those personally taught by them saw no need for instrumental music in worship, I see no need for it either.
God will judge those who worship with instruments, not me. As for me and my house, we'll worship without them, and I would urge every disciple of Jesus to make the same choice. I'm convinced it's the best and right choice!
Grace and peace,
