Many words are used in the New Testament to describe spiritual leaders in the church. Bishop, or overseer (episkipos); elder (presbuteros); pastor; minister (diakonos); evangelist; prophet; teacher; apostle (one sent out). All of these, except perhaps the last, are used interchangeably and appear to be but different functions or gifts of the same office.
An overseer watches for the spiritual well-being of the members of the church. Pastor, or shepherd, is identical in meaning. Elder means much the same, but also implies experienced, but not necessarily aged. A prophet is someone who speaks for God, a preacher. An evangelist is one who brings good news. A teacher gives instruction in the ways of God and the duties of His people. None of these titles should be interpreted to establish a person as a lord over the church.
Apostle is used sparingly in the New Testament, first of all to describe the twelve who were the inner circle of Jesus’ followers. It is also used of Jesus Himself, and of Paul, Barnabas, Timothy and Silas, but does not seem appropriate for any modern day servant of Jesus Christ.
No academic or seminary training is needed to become a minister of the gospel. Indeed, such training is more apt to be a hindrance, introducing psychological and doctrinal concepts that are not in accord with the Bible.
Neither should a minister expect to earn his living by preaching the gospel. A congregation has a duty to support a minister where needed, when he incurs expenses related to the work of the ministry. The congregation also has a duty to the minister’s family when he is absent in the work of the ministry. But he should have an income that does leave him dependent on cultivating the approval of others for his livelihood.
Hundreds of years ago Menno Simons wrote: O my faithful reader, ponder this. As long as the world distributes splendid houses and such large incomes to their preachers, the false prophets and deceivers will be there by droves; and: Therefore this is my brief conclusion and Christian admonition to all preachers and teachers. Brethren, humble yourselves and become unblamable disciples, that you may hereafter become called ministers. Try your spirit, love, and life before you commence to shepherd and to teach. Do not so on your own account, but wait until you are called of the Lord’s church; I say, of the Lord’s church, of the Spirit of God, and are constrained by urging love. If this takes place, brethren, then pastor diligently, preach and teach valiantly, cast from you all filthy lucre and booty; rent a farm, milk cows, learn a trade if possible, do manual labour as did Paul, and all that which you then fall short of will doubtlessly be given and provided you by pious brethren, by the grace of God, not in superfluity, but as necessity requires.
Here then are the qualifications for a minister given by the Apostle Paul in chapter 3 of 1 Timothy.
1. Blameless (above reproach, not derelict in any Christian duty)
2 The husband of one wife (He should be married, but to only one wife at a time. It is certainly permitted for a minister to marry again if his first wife dies, but he must not have any marital entanglement that will be a reproach to his message.)
3. Vigilant (watchful)
4. Sober (prudent)
5. Of good behaviour (orderly and decent)
6. Given to hospitality(literally, a lover of strangers, that is, ready to welcome visitors into his home)
7. Apt to teach (not only wise, but able to make wisdom appealing to others)
8. Not given to wine (does not drink wine to excess, is not domineering or abusive)
9. No striker (not quarrelsome, not a persecutor of those who disagree with him)
10. Not greedy of filthy lucre (not using dishonourable means to increase his income)
11. Patient (gentle)
12. Not a brawler (not contentious)
13. Not covetous (does not seek to be a minister in the hope of material gain)
14. One that ruleth well his own house (has an orderly and respectful family, but not by severity or tyranny)
15. Not a novice (not newly converted but has been a Christian long enough for others to discern the qualities listed here)
16. Have a good report of them which are without (has given no cause for offense or scandal to those outside the church).
One who meets all these qualifications and is called to the ministry by God and the church, is worthy of the respect and support of his fellow believers as he endeavours to serve God in the ministry.
