Those who preach the gospel are sometimes called ministers, evangelists, or preachers. Such names describe aspects of what such men do. The term "preach" means to proclaim. "Evangelist" means a messenger with good news. When a person combines those two ideas they have a messenger proclaiming a good message. A "minister" is anyone who serves others, which is what these men do as they serve the congregation by proclaiming the gospel of Christ.
The New Testament provides to us the gospel of Jesus Christ. "Gospel" means good news. The good message that is proclaimed by preachers is the good news of the death, burial, and resurrection of our Lord and Savior Jesus Christ. Paul makes clear to the young preacher Timothy what the responsibility of a preacher is when he commanded, "...preach the word; be ready in season and out of season; reprove, rebuke, exhort, with great patience and instruction" (2 Timothy 4:2). The word that is to be preached is the inspired word of God found in the Bible (2 Timothy 3:16-17).
Preaching the good news of Jesus requires that such men lovingly serve or minister to the spiritual needs of people with that good news in order that they may grow closer to Jesus Christ.
The preachers/ministers/evangelists of the Chase Park Church of Christ are first and foremost dedicated to the word of God and teaching it in order to bring the lost to Jesus and to strengthen those already saved in Jesus Christ. These men are not the leaders of this congregation, and so they do not have any special title. They are simply servant teachers that love people and want every person to know the love of Jesus Christ.
