The following was originally posted at the Old Light Covenanter blog here. George goes on to list good arguments against the objections against the Psalms.
Lectures in Pastoral Theology, Third Series
Objections to the Book of Psalms
“If the argument presented in the preceding lectures be accepted, then no form of objection that can be raised against the book can set it aside. Since God has provided the psalter by His Holy Spirit, and commanded it to be used; and since He has provided no other, nor promised His aid to any effort to prepare another, it is evident that, in this matter, He has left nothing to the judgment of men. Objections to the psalms, and the praise of hymns as superior to God’s book can have no weight as against the single fact that the psalms are divinely authorized and the hymns are not.”
