All religious organizations are agreed that music has a place in New Testament worship, but are not agreed as to whether it should be vocal or instrumental, or vocal accompanied by instrumental: even though the New Testament, encyclopedists, historians, and commentators make plain the teaching and practice of the New Testament church.

    Let's begin on page 180 in Chapter 24 of the above referenced book: to read the "Declarations of Religious Leaders".

1.  John Calvin, outstanding as one of the founders of the Presbyterian Church:  "Musical instruments in celebrating the praises of God would be no more suitable than the burning of incense, the lighting up of lamps, the restoration of the other shadows of the law.  The Papist, therefore, have foolishly borrowed this, as well as many other things, from the Jews."
-- John Calvin's Commentary, Thirty-third Psalm.

2.  Adam Clarke, the greatest commentator of all time among the Methodists:  "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."
-- Clarke's Commentary, Vol. IV., p. 686

3.  John Wesley, the reputed founder of the Methodist Church, is quoted by Adam Clarke to have said:  "I have no objection to instruments of music, in our chapels, provided they are neither heard nor seen." 
-- Clarke's Commentary, Vol. IV.l, p. 686.

4.  Martin Luther, a distinguished reformer, "called the organ an ensign of Baal"
-- McClintock & Strong's Encyclopedia, Music, Vol. VI., p. 762.

5.  Charles H. Spurgeon, recognized as the greatest Baptist preacher that ever lived, preached for twenty years to thousands of people weekly in the Metropolitan Baptist Tabernacle, London, England, did not have musical instruments in the worship.
-- M. C.Kurfees, Instrumental Music in the Worship, p. 196.

6.  Conybeare and Howson, famous scholars of the Church of England, in commentary on Eph 5:19, say, "Make melody with the music of your hearts, to the Lord......let your songs be, not the drinking of heathen feasts, but psalms and hymns; and their accompaniment not the music of the lyre, but the melody of the heart."
-- Life and Epistles of St. Paul, Vol. II, p. 408.

    The above religious leaders, not one of whom was a member of the church of Christ, have been quoted, not for the purpose of proving instrumental music in the worship wrong--the fact that Christ left it out proves that--but to show that they have been rejected by many religious leaders of the world.  If no one taught instrumental music in the worship is wrong, it would not change the New Testament teaching; but it is evident that others have occupied the same position and that we do not stand here alone by any means. Historians, encyclopedists and religious leaders are agreed that the music characteristic of the New Testament is the music characteristic of the churches of Christ.
