The only office of the Church that has the authority to preach is the pastor, therefore it is wrong for a lay person to preach the gospel.

"Are all apostles? are all prophets? are all teachers? are all workers of miracles?" (1 Corinthians 12:29)

"And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ" (Ephesians 4:11, 12)

"And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also" (2 Timothy 2:2).

An overseer must hold "fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers" (Titus 1:9)
