AQUINAS "Our church does not use musical instruments, as harps and psalteries, to praise God withal, that she may not seem to Judaize." (Thomas Aquinas, Bingham's Antiquities, Vol. 3, page 137)AUGUSTINE "musical instruments were not used. The pipe, tabret, and harp here associate so intimately with the sensual heathen cults, as well as with the wild revelries and shameless performances of the degenerate theater and circus, it is easy to understand the prejudices against their use in the worship." (Augustine 354 A.D., describing the singing at Alexandria under Athanasius)CHRYSOSTOM "David formerly sang songs, also today we sing hymns. He had a lyre with lifeless strings, the church has a lyre with living strings. Our tongues are the strings of the lyre with a different tone indeed but much more in accordance with piety. Here there is no need for the cithara, or for stretched strings, or for the plectrum, or for art, or for any instrument; but, if you like, you may yourself become a cithara, mortifying the members of the flesh and making a full harmony of mind and body. For when the flesh no longer lusts against the Spirit, but has submitted to its orders and has been led at length into the best and most admirable path, then will you create a spiritual melody." (Chrysostom, 347-407, Exposition of Psalms 41, (381-398 A.D.) Source Readings in Music History, ed. O. Strunk, W. W. Norton and Co.: New York, 1950, pg. 70.)CLEMENT "Moreover, King David the harpist, whom we mentioned just above, urged us toward the truth and away from idols. So far was he from singing the praises of daemons that they were put to flight by him with the true music; and when Saul was Possessed, David healed him merely by playing the harp. The Lord fashioned man a beautiful, breathing instrument, after His own imaged and assuredly He Himself is an all-harmonious instrument of God, melodious and holy, the wisdom that is above this world, the heavenly Word." … "He who sprang from David and yet was before him, the Word of God, scorned those lifeless instruments of lyre and cithara. By the power of the Holy Spirit He arranged in harmonious order this great world, yes, and the little world of man too, body and soul together; and on this many-voiced instruments of the universe He makes music to God, and sings to the human instrument. "For thou art my harp and my pipe and my temple"(Clement of Alexandria, 185AD, Readings p. 62)EUSEBIUS "Of old at the time those of the circumcision were worshipping with symbols and types it was not inappropriate to send up hymns to God with the psalterion and cithara and to do this on Sabbath days... We render our hymn with a living psalterion and a living cithara with spiritual songs. The unison voices of Christians would be more acceptable to God than any musical instrument. Accordingly in all the churches of God, united in soul and attitude, with one mind and in agreement of faith and piety we send up a unison melody in the words of the Psalms." (commentary on Psalms 91:2-3)CLARKE "But were it even evident, which it is not, either from this or any other place in the sacred writings, that instruments of music were prescribed by divine authority under the law, could this be adduced with any semblance of reason, that they ought to be used in Christian worship? No; the whole spirit, soul, and genius of the Christian religion are against this; and those who know the Church of God best, and what constitutes its genuine spiritual state, know that these things have been introduced as a substitute for the life and power of religion; and that where they prevail most, there is least of the power of Christianity. Away with such portentous baubles from the worship of that infinite Spirit who requires His followers to worship Him in spirit and truth, for to no such worship are these instruments friendly." (Adam Clarke (Methodist), Clarke's Commentary, Methodist, Vol. II, pp. 690-691.)SCHAFF "In the Greek church the organ never came into use. But after the 8th century it became more and more common in the Latin church; not without opposition from the side of the monks." (Schaff-Herzogg Encyclopedia, Vol 10, p. 657-658)
SHAFF (new) "The custom of organ accompaniment did not become general among Protestants until the eighteenth century." (The New Shaff-Herzogg Encyclopedia, 1953, Vol 10, p. 257)SPURGEON "David appears to have had a peculiarly tender remembrance of the singing of the pilgrims, and assuredly it is the most delightful part of worship and that which comes nearest to the adoration of heaven. What a degradation to supplant the intelligent song of the whole congregation by the theatrical prettiness of a quartet, bellows, and pipes. We might as well pray by machinery as praise by it...'Praise the Lord with harp.' Israel was at school, and used childish things to help her to learn; but in these days when Jesus gives us spiritual food, one can make melody without strings and pipes... We do not need them. That would hinder rather than help our praise. Sing unto him. This is the sweetest and best music. No instrument is like the human voice." (Charles Spurgeon (Baptist), Commentary on Psalm 42.)WESLEY 'I have no objection to instruments of music in our worship, provided they are neither seen nor heard." (John Wesley, founder of Methodism, quoted in Adam Clarke's Commentary, Vol. 4, p. 685)CATHOLIC "Although Josephus tells of the wonderful effects produced in the Temple by the use of instruments, the first Christians were of too spiritual a fibre to substitute lifeless instruments for or to use them to accompany the human voice. Clement of Alexandria severely condemns the use of instruments even at Christian banquets. St. Chrysostum sharply contrasts the customs of the Christians when they had full freedom with those of the Jews of the Old Testament." (Catholic Encyclopedia, Vol. 10, pg. 648-652.)I don’t know specifically how things developed on your side of the pond, but I do know that if we were magically transported to North America as late as the 1820s and entered various houses of evangelical worship, be they Methodist, Baptist, Presbyterian or Congregational, at that time, the probability of us hearing praises sung without instruments was probably about 65-70%.PRESBYTERIAN "Question 6. Is there any authority for instrumental music in the worship of God under the present dispensation? Answer. Not the least, only the singing of psalms and hymns and spiritual songs was appointed by the apostles; not a syllable is said in the New Testament in favor of instrumental music nor was it ever introduced into the Church until after the eighth century, after the Catholics had corrupted the simplicity of the gospel by their carnal inventions. It was not allowed in the Synagogues, the parish churches of the Jews, but was confined to the Temple service and was abolished with the rites of that dispensation." (Questions on the Confession of Faith and Form of Government of The Presbyterian Church in the United States of America, published by the Presbyterian Board of Publications, Philadelphia, Pennsylvania, 1842, pg. 55.)
It is simply a fact that for almost the first 700 years the Church sang without instrumental accompaniment, by conviction. At that time there was 1 organ. Organ accompaniment did not develop to any significant level until 1100-1200. All other instrumentation accompaniment came subsequent to this.
As far as I am aware all Eastern Orthodox Church (The only UnReformed Church) refrain from using instrument to this day.
As for Protestant worship, as Schaff says above instruments weren’t used much at all until the 18th Century and did not gain prevalence until much later. Instruments accompaniment in the public worship of God as the norm, or as the prevailing practice has only about a 150 year history. Those are just the facts at least here in the US.
I don’t know what hymnal you use, but the one I am familiar with from my Naz years is Sing to the Lord. Check all the hymns written by the Wesleys, you note that not one “tune” is attributed to either Wesley brother. Why? Because they were written in Metre, to be sung to various tunes with the human voice, sans instrumental accompaniment, just as most hymns were at that time and even much later.
Here in the US, if I ask ‘what tune is this?’; and start humming a certain tune, virtually everyone over the age of 20, believer or unbeliever is going to answer, ‘Amazing Grace!.’ That answer would be wrong! The tune is New Britian which is a 19th Century American melody, arranged by Edwin O. Excell. Newton published Amazing Grace in 1779!
Here is the Campbellite link from which I culled the few quotes above. You can see there are plenty more.
If you are seriously interested in the History I recommend:
Instrumental Music in the Public Worship of the Church by John Lafayette Girardeau from 1888. This is the classic work on the subject. (I linked to achive.org above but here it is at Google Books if you prefer.)
A great, outstanding even, contemporary treatment can be found in:
Old Light on New Worship: Musical Instruments and the Worship of God, a Theological, Historical and Psychological Study by John Price.
The author is a Baptist from Rochester NY, and is not an exclusive psalmist. It is a very well researched book but quite easy to read for anyone.
Online you can read:
Musical Instruments in the Public Worship of God by Brian Schwertley
This is more of a polemic, and written from the Presbyterian RPW perspective but the research is solid. (It is a bit long in for computer reading IMO. But, you know how to save it as a mobi or a txt for your Kindle )
If you break the Christian Church down by time and preponderance of use when it comes to instruments in worship; in very, very round numbers you get about 1800 years of intentional acappella worship and slightly lest then 200 years of instrumental accompaniment.
You are certainly entitled to you opinion, but there is a significant Historical cloud of witnesses that have a differing opinion.
