"Among the numerous and highly interesting predictions with regard to the future glory of Zion, it is foretold, that her 'watchmen shall lift up the voice; with the voice together shall they sing; for they shall see eye to eye, when the Lord shall bring again the captivity of Zion.'

For the arrival of this period of joy and unanimity among the watchmen of Zion, the church has for ages been employed in making prayer and supplication before God. It still remains true, however, to some extent, that diversity of opinion prevails among the watchmen of Zion; and in some parts of religious worship, they cannot 'lift up the voice together.' And in no part of religious worship does this diversity more unhappily appear, than in the delightful exercise of celebrating God's praise.

Some believe, that in this part of divine worship, we have no authority to use any other 'psalms, and hymns, and spiritual songs,' than those which God has furnished in his word; while others maintain that we are at liberty to use those which have been composed by uninspired men, that matter of which they have collected out of the Scriptures.

It is easy to see, that such a difference in principle must exert a powerful influence in perpetuating division, and in preventing union in the church of God. To endeavor, in the use of all proper means, to remove this cause of division among brethren supposes that there is a fault somewhere, it should be the concern of every one to ascertain whether his principles and practice on this subject are conformable to the word of God. For on those who forsake, and not on those who hold fast the 'law and the testimony,' must the fault or division lie" states the author.

This book, of 180 pages, endeavors to correct this division by defending the position of Apostolic church -- which was exclusive Psalmody.

This is the second edition, "enlarged by two additional chapters, embracing a critical analysis of Col. 3:16-17 and the modern history (from the apostolic age to the author's day--RB) of Psalmody."
