We ourselves, too, are prophets or sons and pupils of the prophets. Nor is it necessary that future events be revealed to us. For the office of a prophet it is enough that we understand Scripture and are able to teach others and also to help one another with prayers. For he who is not a prophet is unable to teach, pray, and do any good work.
Therefore the name “prophet” belongs equally to all Christians, and he who denies this also denies that he has been baptized and has been instructed through the Word.
