This question stimulates intriguing
discussion among pastors and church leaders.
It has been said to me, “I am a teacher, not a preacher.” Interestingly, no one has ever said the
opposite! Some suggest that there is no
difference between the two. They say the
two terms as virtually synonymous. My
position is that there is a distinction, but not a radical division. It helps to state it this way:
You
can be a teacher and not a preacher; but
You
cannot be a preacher without being a teacher.
An important text of Scripture that gives
rise to this definition is found in 2 Timothy 4:1–2 (ESV):
“4 I charge you in the
presence of God and of Christ Jesus, who is to judge the living and the dead,
and by his appearing and his kingdom: 2 preach the word; be
ready in season and out of season; reprove, rebuke, and exhort, with complete
patience and teaching.”
Notice this important call to Paul’s
protégé, Timothy: “Preach the word . . . with patience and teaching.” The
imperative is to “preach”. The Greek
word is translated “herald” or “proclaim” and he is to do it with “teaching”
(with doctrine or instruction). To read
on in 2 Timothy we learn of a time when people will not welcome this “sound
teaching” v3. Sound teaching or sound
doctrine is the content of the word preached.
Exegetically we can discern that to preach includes the elements of
“reproving, rebuking and exhorting.” I
would argue that you can conduct instruction that conveys doctrinal
understanding to the hearer. Left in that alone it is defined as teaching. The preacher though takes the sound teaching
and in love and concern for the hearer brings reprimand, conviction of sin, a
stern warning, comfort and encouragement.
There is a Spirit endowed authority with true preaching. This diagram is a facsimile of my position [:

This emotion that is implied in Biblical
preaching is that blend of compassion and passion. Martyn Lloyd-Jones defined preaching this
way:
“What is preaching? Logic on fire!
Preaching is theology coming through a man who is on fire. A true understanding
and experience of the Truth must lead to this. I say again that a man who can
speak about these things dispassionately has no right whatsoever to be in a
pulpit; and should never be allowed to enter one.”
J.I. Packer presses in deeper by stating
that the “preacher” conveys the Word of God through His “commands, promises,
warnings, and assurances, with a view to winning the hearer or hearers…to a
positive response.”] My father had a book on his shelf entitled,
Preaching to Convince. There is a sense
where the preacher, more so than the teacher, is burning to be persuasive,
pressing the urgency of the doctrine onto the hearer and seeking the right
response through invitation.
It is no accident that the Greek word for
the preacher represents a herald, a town crier.
The herald is a representative of the king and has a message that the
subjects need to hear. Certainly, the
herald must represent the king’s message with precision, but he is also
endowed with a serious responsibility to ensure that people hear and respond to
the message. His job is not to provide facts and information. His job is to press the facts and information
on the minds and wills of the citizens.
Now what of a person who is preaching
(so-called) but is devoid of the essence of teaching? I have witnessed such things in the name of
preaching. I think of them as nothing
but circus clowns parading themselves back and forth across the stage, ranting
and railing, throwing out nothing but carefully designed memes, entertaining
their audience with their performance. Preaching
without teaching is not preaching.
There is a role for teachers in the
church. “Teaching, on the other hand, if
done well, is dialogical [a discussion with students. A conversation.] by
nature. The communication of content is driven by the teacher, but questions
from the hearers shape the conversation and interchange that happens in the
classroom. Good teaching is inherently dialogical.”1
So, there is a need for sound doctrinal,
albeit dialogical teachers in the Church. They provide insight into systematic
and Biblical theology. They instruct the
listeners in doctrine. Their goal is to
provide information that equips. Often, they are seen as discipling
believers. But the essential need for
the Church is for preachers. They are transformational
in their approach. They warn. They
correct. They bring Gospel comfort and encouragement in the Lord. They have a
fire within that cannot be quenched. As
prophets of old they come with a “burden”.
So yes, there are teachers that are not
preachers. But Biblical preachers —
preachers representing the King of kings approach their congregation with a
compassion driven passion to conform people to the likeness of Christ in
Christian maturity.
“Him we proclaim, warning everyone and
teaching everyone with all wisdom, that we may present everyone mature in
Christ.” - Colossians 1:28 (ESV)
