No reader of the New Testament can doubt that the Apostles were prophets; but as a prophet does not always speak by revelation, but only, at rare intervals, as we showed at the end of Chap. I., we may fairly inquire whether the Apostles wrote their Epistles as prophets, by revelation and express mandate, as Moses, Jeremiah, and others did, or whether only as private individuals or teachers, especially as Paul, in Corinthians xiv:6, mentions two sorts of preaching.
