I have not sent these prophets, yet they ran: I have not
spoken to them, yet they prophesied. (Jer. 23:21)
We hence learn also that our ears ought not to be open to
impostors, who boldly pretend the name of God, but that we ought to distinguish
between true and false teachers; for Jeremiah does not here speak to a few men,
but he addresses the whole people. And what he designed to shew was, that they
in vain sought to escape under the pretense of ignorance, who were not
attentive to sound doctrine; for except they designedly neglected God and his
word, they might have known whom to believe. It hence follows that frivolous is
the excuse which many consider at this day to be as it were their sacred
asylum; for they plead in their own behalf they have been deceived by false
teachers. But we ought to see and to inquire whether God has sent them, and
whether they teach as coming from his school, and bring anything but what they
have received from his mouth.
I shall not here speak at large of God's call; but if any
one wishes for a very short definition, let him take the following: There is a
twofold call; one is internal and the other belongs to order, and may,
therefore, be called external or ecclesiastical. But the external call is never
legitimate, except it be preceded by the internal; for it does not belong to us
to create prophets, or apostles, or pastors, as this is the special work of the
Holy Spirit. Though then one be called and chosen by men a hundred times, he
cannot yet be deemed a legitimate minister, except he has been called by God;
for there are peculiar endowments required for the prophetic, the apostolic,
and the pastoral office, which are not in the power or at the will of men. We
hence see that the hidden call of God is ever necessary, in order that any one
may become a prophet, or an apostle, or a pastor. (Commentaries)
