[IMGL]http://i39.tinypic.com/v3j0hx.jpg[/IMGL]John T. Pressly was professor of Systematic Theology at Western Theological Seminary (a precursor institution to Pittsburgh Theological Seminary) and a minister in the Associate Reformed Presbyterian Church. This work was one of several he wrote defending the ARP position on Psalmody (which the ARP has not held since 1946). What is unique about this particular book is that it was written as a lengthy review of a treatise defending the use of uninspired hymnody and in doing so it deals with a lot of the common objections to the EP position. It is about 150 pages and I recommend it for your perusal. “Review of Ralston’s Inquiry into the propriety of using an evangelical Psalmody in the worship of God. 2nd ed. (1848)” A couple quotations can be found here and here.
