1 Timothy 3:1-13 (ESV)
The saying is trustworthy: If anyone aspires to the office of overseer, he desires a noble task. 2 Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach, 3 not a drunkard, not violent but gentle, not quarrelsome, not a lover of money. 4 He must manage his own household well, with all dignity keeping his children submissive,5 for if someone does not know how to manage his own household, how will he care for God's church? 6 He must not be a recent convert, or he may become puffed up with conceit and fall into the condemnation of the devil. 7 Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace, into a snare of the devil.
8 Deacons likewise must be dignified, not double-tongued, not addicted to much wine, not greedy for dishonest gain. 9 They must hold the mystery of the faith with a clear conscience. 10 And let them also be tested first; then let them serve as deacons if they prove themselves blameless. 11 Their wives likewise must be dignified, not slanderers, but sober-minded, faithful in all things. 12 Let deacons each be the husband of one wife, managing their children and their own households well. 13 For those who serve well as deacons gain a good standing for themselves and also great confidence in the faith that is in Christ Jesus.
Titus 1:5-9 (ESV)
5 This is why I left you in Crete, so that you might put what remained into order, and appoint elders in every town as I directed you-- 6 if anyone is above reproach, the husband of one wife, and his children are believers and not open to the charge of debauchery or insubordination. 7 For an overseer, as God's steward, must be above reproach. He must not be arrogant or quick-tempered or a drunkard or violent or greedy for gain, 8 but hospitable, a lover of good, self-controlled, upright, holy, and disciplined. 9 He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it.
Book of Church order
8-1. This office is one of dignity and usefulness. The man who fills it has in Scripture different titles expressive of his various duties. As he has the oversight of the flock of Christ, he is termed bishop or pastor. As it is his duty to be grave and prudent, an example to the flock, and to govern well in the house and Kingdom of Christ, he is termed presbyter or elder. As he expounds the Word, and by sound doctrine both exhorts and convinces the gainsayer, he is termed teacher. These titles do not indicate different grades of office, but all describe one and the same office.
8-2. He that fills this office should possess a competency of human learning and be blameless in life, sound in the faith and apt to teach. He should exhibit a sobriety and holiness of life becoming the Gospel. He should rule his own house well and should have a good report of them that are outside the Church.
8-3. It belongs to those in the office of elder, both severally and jointly, to watch diligently over the flock committed to his charge, that no corruption of doctrine or of morals enter therein. They must exercise government and discipline, and take oversight not only of the spiritual interests of the particular church, but also the Church generally when called thereunto. They should visit the people at their homes, especially the sick. They should instruct the ignorant, comfort the mourner, nourish and guard the children of the Church. They should set a worthy example to the flock entrusted to their care by their zeal to evangelize the unconverted and make disciples. All those duties which private Christians are bound to discharge by the law of love are especially incumbent upon them by divine vocation, and are to be discharged as official duties. They should pray with and for the people, being careful and diligent in seeking the fruit of the preached Word among the flock.
8-4. As the Lord has given different gifts to men and has committed to some special gifts and callings, the Church is authorized to call and appoint some to labor as teaching elders in such works as may be needful to the Church. When a teaching elder is called to such needful work, it shall be incumbent upon him to make full proof of his ministry by disseminating the Gospel for the edification of the Church. He shall make a report to the Presbytery at least once each year.
8-5. When a man is called to labor as a teaching elder, it belongs to his order, in addition to those functions he shares with all other elders, to feed the flock by reading, expounding and preaching the Word of God and to administer the Sacraments. As he is sent to declare the will of God to sinners, and to beseech them to be reconciled to God through Christ, he is termed ambassador. As he bears glad tidings of salvation to the ignorant and perishing, he is termed evangelist. As he stands to proclaim the Gospel, he is termed preacher. As he dispenses the manifold grace of God, and the ordinances instituted by Christ, he is termed steward of the mysteries of God.
8-6. When a teaching elder is appointed to the work of an evangelist in foreign countries or where there are no other PCA churches within a reasonable distance, he is commissioned for a renewable term of twelve months to preach the Word, to administer the Sacraments, to receive and dismiss members of mission churches, and to train potential officers. By separate actions the Presbytery may in extraordinary situations commission him to examine, ordain and install ruling elders and deacons and organize churches.
8-7. A Presbytery may, at its discretion, approve the call of a teaching elder to work with an organization outside the jurisdiction of the Presbyterian Church in America, provided that he be engaged in preaching and teaching the Word, that the Presbytery be assured he will have full freedom to maintain and teach the doctrine of our Church, and that he report at least annually on his work. As far as possible, such a teaching elder shall be a member of the Presbytery within whose bounds he labors. (See BCO 20-1.)
8-8. As there were in the Church under the law, elders of the people for the government thereof, so in the Gospel Church, Christ has furnished others besides ministers of the Word with gifts and commission to govern when called thereunto, who are called ruling elders.
8-9. Elders being of one class of office, ruling elders possess the same authority and eligibility to office in the courts of the Church as teaching elders. They should, moreover, cultivate zealously their own aptness to teach the Bible and should improve every opportunity of doing so.
9-1. The office of deacon is set forth in the Scriptures as ordinary and perpetual in the Church. The office is one of sympathy and service, after the example of the Lord Jesus; it expresses also the communion of saints, especially in their helping one another in time of need.
9-2. It is the duty of the deacons to minister to those who are in need, to the sick, to the friendless, and to any who may be in distress. It is their duty also to develop the grace of liberality in the members of the church, to devise effective methods of collecting the gifts of the people, and to distribute these gifts among the objects to which they are contributed. They shall have the care of the property of the congregation, both real and personal, and shall keep in proper repair the church edifice and other buildings belonging to the congregation. In matters of special importance affecting the property of the church, they cannot take final action without the approval of the Session and consent of the congregation. In the discharge of their duties the deacons are under the supervision and authority of the Session. In a church in which it is impossible for any reason to secure deacons, the duties of the office shall devolve upon the ruling elders.
9-3. To the office of deacon, which is spiritual in nature, shall be chosen men of spiritual character, honest repute, exemplary lives, brotherly spirit, warm sympathies, and sound judgment.
9-4. The deacons of a particular church shall be organized as a Board, of which the pastor shall be an advisory member. The Board shall elect a chairman and a secretary from their number and a treasurer to whom shall be entrusted the funds for the current expenses of the church. It shall meet separately at least once a quarter, and whenever requested by the Session. The Board of each church shall determine the number necessary for a quorum. The Board shall keep a record of its proceedings, and of all funds and their distribution, and shall submit its minutes to the Session regularly, and at other times upon request of the Session. It is desirable that the Session and the Board of Deacons meet in joint session once a quarter to confer on matters of common interest.
9-5. Deacons may properly be appointed by the higher courts to serve on committees, especially as treasurers. It is suitable also that they be appointed trustees of any fund held by any of the Church courts. It may also be helpful for the Church courts, when devising plans of church finance, to invite wise and consecrated deacons to their councils.
9-6. The deacons may, with much advantage, hold conference from time to time for the discussion of the interests committed to them. Such conferences may include representatives of churches covering areas of smaller or larger extent. Any actions taken by these conferences shall have only an advisory character.
9-7. It is often expedient that the Session of a church should select and appoint godly men and women of the congregation to assist the deacons in caring for the sick, the widows, the orphans, the prisoners, and others who may be in any distress or need. These assistants to the deacons are not officers of the church (BCO 7-2) and, as such, are not subjects for ordination (BCO 17).
