"Musical instruments in celebrating the praises of God would be no more suitable than the burning of incense, the lighting up of lamps, and the restoration of the other shadows of the law. The papists, therefore, have foolishly borrowed this, as well as many other things, from the Jews. Men who are fond of outward pomp may delight in that noise; but the simplicity which God recommends to us by the apostle is far more pleasing to Him" - John Calvin, Presbyterian founder (Commentary on Psalms 33 and on I Samuel 18: 1-9). (See Ephesians 5: 19, dm.)
"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 like the human voice" -Charles Spurgeon whom some believed to have been the greatest Baptist preacher (Commentary on Psalms 42).
"I am an old man, and an old minister; and I here declare that I never knew them productive of any good in the worship of God; and have had reason to believe that they were productive of much evil. Music, as a science, I esteem and admire: but instruments of music in the house of God I abominate and abhor. This is the abuse of music; and here I register my protest against all such corruptions in the worship of the Author of Christianity. The late and venerable and most eminent John Wesley, who was a lover of music, and an elegant poet, when asked his opinion on instruments of music being introduced into the chapels of the Methodists, said in his terse and powerful manner, 'I have no objections to instruments of music in our chapels, provided they are neither heard nor seen' I say the same" -Adam Clarke, acclaimed Methodist Commentator (Clarke's Commentary, Vol. 4, pg. 684).
"Although Josephus tells of the wonderful effects produced in the Temple by the use of instruments, the first Christians were of too spiritual a fiber 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. 652).
"Pope Vitalian is related to have first introduced organs into some of the churches of western Europe about 670; but the earliest trustworthy account is that of the one sent as a present by the Greek Emporer Constantine Copronymos, to Pepin, King of the Franks, in 775 (A.D., dm.)" -American Encyclopedia, Vol. 12, 688).
