It's this in Warfield's multivolume Works?
I believe this is an early monograph that didn't make it into the collected works.
Hi Phil, I published a thread on this work on 02-20-17 (LINK).The contribution first appeared as a booklet in 1891, and an expanded edition of it was published in 1897 in the book titled, Two Studies in the History of Doctrine.Wipf and Stock Publishers reprinted the 1897 edition in 2001, but it is not found any of the collected editions that I am aware of—e.g. the 10 volume, "Works of B. B. Warfield", Oxford 1829/Baker 1981; the 4 volume Presbyterian and Reformed set; the 2 volume, "Selected Shorter Writings" also by Presbyterian and Reformed.Grace and peace,David
