All ministers are not called to the pastorate; and it is sometimes the
duty of those who were once called to that position to leave it and
enter a different department of ministerial work. In the ministry which
the ascended Christ gives His church, besides pastors, there are
"evangelists" and "teachers"--terms designating important classes of
ministers permanently existing in the kingdom of God. A brief
characterization of these, and of the functions with which they are
charged, may properly be presented here.
