As has been said, God's ordering for the Kingdom life of His People relies on elders. Nevertheless, in the oversight of God's work, they need assistance with certain areas .
For that purpose Paul confirms the ministry of Servants that was brought into being earlier (Acts 6'1-6).
In his letter to the Philippian Believers he describes the order of a local Kingdom Ekklesia:
"... all the Saints in Christ Jesus ... in Philippi with ... Elders and Servants".
(For more go to Kingdom Servants on the Menu).
Significantly, before going on to talk about appointing Elders, in Titus 1'1 Paul refers to his own ministry concerning the ...
"... acknowledgment of the truth which accords with godliness".
This is where Elders are to be. Their thinking is to be in harmony with the truth of the Lord Jesus the word of Christ.
Titus and Timothy had that disposition and they were charged with the job of appointing elders.
To Titus Paul said:
“… if a man is blameless, the husband of one wife, having faithful children not accused of dissipation or insubordination.
For an overseer must be blameless, as a steward of God, not self-willed, not quick-tempered, not given to wine, not violent, not greedy for money,
but hospitable, a lover of what is good, sober-minded, just, holy, self-controlled,
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,” Titus 1’6-9.
To Timothy Paul said:
"This is a faithful saying: If a man desires to be an overseer, he desires a good work.
An overseer then must be blameless, the husband of one wife, temperate, sober-minded, of good behaviour, hospitable, able to teach;
not given to wine, not violent, not greedy for money, but gentle, not quarrelsome, not covetous;one who rules his own house well, having his children in submission with all reverence
(for if a man does not know how to rule his own house, how will he take care of the People ofGod?);
not a novice, lest being puffed up with pride he fall into the same condemnation as the devil.
Moreover he must have a good testimony among those who are outside, lest he fall into reproach and the snare of the devil," 1 Timothy 3'1-7.
This is the godliness that marks out the Believer who can be trusted with the shepherding and overseeing of the Flock of God.
