The apostolic letters. The New Testament contains twenty-one in all. They are divided into two classes. (1.) Paul's Epistles, fourteen in number, including Hebrews. These are not arranged in the New Testament in the order of time as to their composition, but rather according to the rank of the cities or places to which they were sent. Who arranged them after this manner is unknown. Paul's letters were, as a rule, dictated to an amanuensis, a fact which accounts for some of their peculiarities. He authenticated them, however, by adding a few words in his own hand at the close. (See GALATIANS, EPISTLE TO.)
