Of no New Testament book can it be said with certainty that the titles were given to them by their authors. The documents from which they are derived differ amongst themselves. Some give long, others short titles, the latter being generally the more ancient. Thus in the oldest copy, we have as the title of the fifth book, merely " Acts," which the " Vatican " (B) expands into " Acts of Apostles," but a scribe of the " Alexandrine " MS (A) in the subscription-which is all that remains-into " Acts of the Holy Apostles." The subscriptions of the following books are quite misleading: First Corinthians, Galatians, First and Second Thessalonians, First Timothy, and Titus, as Paley has shown.
