It will do no harm to iterate here that the two essentials to a successful hymn are spirituality and the power to express it so as to reach the understanding as well as the hearts of the people who are to sing. According to Paul, the first commandment in hymn writing and singing is: “I will sing with the spirit”; the second is like unto it: “I will sing with the understanding also.” _Chapter IV_ THE EMENDATION OF HYMNS I. THE CHANGES IN OUR HYMNS _Early Changes._ The question of changes made in hymns by others than their writers deserves consideration. The point is not that the individual preacher is supposed to air his critical skill, but that he should understand why changes have been made by hymnal editors and better appreciate the principles involved and the literary niceties that are to be observed. In the first compilations of hymnbooks, the rights of the authors of the individual hymns were entirely below the horizon. Many hymns were published without the names of their writers. To this day Charles Wesley’s claim to “Jesus, Lover of My Soul,” as against that of his brother John, depends wholly on considerations of style and form of stanza. There is not even a well-founded tradition. It was the adaptation of the hymn to immediate actual needs that counted, not the writer. There was no moral copyright, much less legal, to stay the hand of the mutilator. Watts did not hesitate to incorporate in his hymns lines and even whole stanzas from the hymns of others. John Wesley had no scruples in rewriting lines and stanzas and even whole hymns already in print. Toplady’s alterations were often quite radical, as, for example, his drastic revision of Charles Wesley’s “Blow ye the trumpet, blow”[1] to suit his intensely Calvinistic views. _The Abuse of the Editorial Revision._ Dr. Worcester, in this country, who issued several collections of psalms and hymns, chiefly by Watts, was lavish in his alterations, mostly for the worse—so much so that the New England churches revolted. Lord Selborne said of these mutilations by many hands, “There is just enough of Watts left here to remind one of Horace’s saying that ‘you may know the remains of a poet even when he is torn to pieces.’”
