Another fine selection from the Reformed Covenanter website:
“We have always thought that the serious imperfections that are justly chargeable upon the most favourite uninspired hymns furnish a powerful argument against employing them in the Psalmody of the Church. The Inspired Psalms, as being the dictates of the Spirit of truth, are entirely free from error, and although, in some cases, we may be unable to discover the application of the figures, or the full import of the expressions, we cannot hesitate for a moment to declare, that in arrangement, expression, and design, the psalms are absolutely perfect. To say otherwise, as some modern hymn-makers have done, is to charge the Author of inspiration with imperfection, and to cast contempt on his best gift to our world. No such declaration, however, can, with propriety, be used in relation to those merely human compositions which have been introduced to rank with the Psalms of David, or, in many cases, to supplant them, in the praises of the Church. Select the most esteemed of them, and they will be found, either in matter, or style, or arrangement, to betray evident marks of human imperfection: in some instances, noxious error it diffused under the embellishments of poetry; in others, the style is turgid, abounding in puerile conceits or unnatural images, and forced expressions; while, in almost all, there is a wide departure from the unadorned simplicity and dignified gravity of the Words of the Holy One of Israel.” Rev. Thomas Houston
