Him we proclaim, warning everyone and teaching everyone with all wisdom, that we may present everyone mature in Christ. (Colossians 1:28 ESV)
And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ. (Ephesians 4:11-13 ESV)
Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world. (James 1:27 ESV)
The saying is trustworthy: If anyone aspires to the office of overseer, he desires a noble task. Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach, not a drunkard, not violent but gentle, not quarrelsome, not a lover of money. He must manage his own household well, with all dignity keeping his children submissive, for if someone does not know how to manage his own household, how will he care for God’s church? He must not be a recent convert, or he may become puffed up with conceit and fall into the condemnation of the devil. Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace, into a snare of the devil. Deacons likewise must be dignified, not double-tongued, not addicted to much wine, not greedy for dishonest gain. They must hold the mystery of the faith with a clear conscience. And let them also be tested first; then let them serve as deacons if they prove themselves blameless. Their wives likewise must be dignified, not slanderers, but sober-minded, faithful in all things. Let deacons each be the husband of one wife, managing their children and their own households well. 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. (1 Timothy 3:1-13 ESV)
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– 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. 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, but hospitable, a lover of good, self-controlled, upright, holy, and disciplined. 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. (Titus 1:5-9 ESV)
