The first century church needed some guidance on the qualifications of elders, as we see in Paul’s letters to Timothy and Titus. When a new elder is being sought, these qualifications are very important to the selection of that man or those men.
1 Timothy 3:1-7 (NKJV)
1 This is a faithful saying: If a man desires the position of a bishop, he desires a good work.
2 A bishop then must be blameless, the husband of one wife, temperate, sober-minded, of good behavior, hospitable, able to teach;
3 not given to wine, not violent, not greedy for money, but gentle, not quarrelsome, not covetous;
4 one who rules his own house well, having his children in submission with all reverence
5 (for if a man does not know how to rule his own house, how will he take care of the church of God?);
6 not a novice, lest being puffed up with pride he fall into the same condemnation as the devil.
7 Moreover he must have a good testimony among those who are outside, lest he fall into reproach and the snare of the devil.
Titus 1:5-9 (NKJV)
5 For this reason I left you in Crete, that you should set in order the things that are lacking, and appoint elders in every city as I commanded you--
6 if a man is blameless, the husband of one wife, having faithful children not accused of dissipation or insubordination.
7 For a bishop must be blameless, as a steward of God, not self-willed, not quick-tempered, not given to wine, not violent, not greedy for money,
8 but hospitable, a lover of what is good, sober-minded, just, holy, self-controlled,
9 holding fast the faithful word as he has been taught, that he may be able, by sound doctrine, both to exhort and convict those who contradict.
