1 Timothy 3:8-10, 12, 13

For the men who minister in a fine manner are acquiring for themselves a fine standing and great freeness of speech in the faith in connection with Christ Jesus.”

We can see here that no minimum age for appointment as a ministerial servant is stipulated. So when the elders meet to discuss the qualifications of males in the congregation, they can bear in mind that there is no Biblical basis for requiring that a Christian man be 20, 25, or 30 years of age before he can be recommended and serve. The Bible refers to those who hold this office as being “men who minister,” so we would hardly expect them to be in their early or middle teenage years. Bearing this out, the Bible says that such ministerial servants might be married and have children themselves.
