A preacher has something to announce before he has something to invent. Paul identifies that message as Christ crucified. The apparent weakness of the subject does not authorize replacing it with whatever seems more impressive.
The Word
κηρύσσω (kēryssō) means to proclaim or preach. It is a verb associated with making a message publicly known. The related noun Kerygma names proclamation or what is proclaimed.
The verb does not specify a single speaking style, volume, or length. Nor does it make every public announcement a sermon. The speaker’s commission and the content proclaimed distinguish its Christian use.
Range of Meaning
Mark uses the verb for John the Baptist’s preaching and for Jesus’ proclamation of God’s kingdom. Romans 10 connects preaching with sending, hearing, and believing. Second Timothy 4:2 commands Timothy to preach the Word amid resistance to sound teaching.
The same broad language can also describe publicizing events. We should not make the dictionary definition itself carry the whole doctrine of the ministry. The calling and message emerge from the passages in which the verb appears.
Where You’ll Meet It
Paul writes:
“we preach about a crucified Christ” (1 Corinthians 1:23, NET)
First Corinthians 1:18–25 contrasts the message of the cross with the demands for impressive wisdom or signs. Paul does not apologize for Christ’s death as an unfortunate preliminary to a more marketable subject. He identifies God’s saving power within the message that appears foolish.
Romans 10:14–17 then asks how people will hear without someone preaching and how preachers will preach unless sent. Faith comes through hearing the message concerning Christ. The messenger serves a Word received from another.
What Confessional Lutherans Hear
Augsburg Confession V confesses that God instituted the office of preaching and gave the gospel and sacraments so that faith might be obtained. Through these means the Holy Spirit works in those who hear the gospel.
That is a strong reason to take preaching seriously without making the preacher a spiritual celebrity. The effectiveness belongs to God’s Word and Spirit. Eloquence can aid understanding, but it cannot replace the message or manufacture conversion.
The distinction between law and gospel also matters. God’s law names and condemns sin; the gospel announces Christ’s saving gift for sinners. A sermon that never gives that gift may offer accurate advice while failing to deliver the consolation the conscience needs.
Where People Get It Wrong
A vivid delivery can conceal an absent gospel. Conversely, a modest delivery does not make Christ’s promise weak. The proper question concerns the message being preached and its faithful application.
It is also possible to mention the cross without proclaiming what it gives. A reference to Jesus used only to reinforce a demand for better behavior leaves the hearer carrying the burden the gospel addresses.
So What
Listen for what Christ has done and what he promises to you. Receive faithful admonition, but do not mistake your improved behavior for the foundation of God’s mercy.
Pray for those called to preach, and support their work. The Church needs messengers who can speak clearly because they have first listened carefully.
