Professor Girardeau begins with general arguments from scripture. From there, he moves into specific arguments from the Old Testament, then the New Testament. Even though a staunch Presbyterian himself, he uses this book as a last stand, appealing to Presbyterians worldwide to maintain their purity of worship without a musical instrument at a time when most in his denomination have already purchased an organ or piano and have no intention of going back to the old ordinary ways. In fairness, he gives all the arguments in favor of keeping instruments to back up their worship singing. On his final page after warning other worshipers that it will eventually end in the decline of true personal spirituality and Christianity, the reader can almost see him penning his last words in tears: "In the name of the framers of our venerable standards, in the name of the reformers, divines, and martyrs of the Presbyterian Church, in the name of Christ's true witness in the centuries of the past, in the name of our glorious King and Head, we erect our solemn PROTEST."
