This word primarily means an older man, one of age, wisdom and spiritual maturity. This word means an overseer. The pastors of the church, as shepherds, care for the souls of the congregation, the sheep of God's pasture, in the same way that shepherds care for their flocks. So these terms tell us who these men are, what they do and how they do it. They see that Christ's laws are carried out.
Elders have a great work and a great responsibility.
Nevertheless, it is possible for elders to make a decision that would violate the teaching of the Lord. In that case the Lord must always be obeyed, and it would not be wrong to go against the decision of the elders. The widespread digression that came to the church many years ago would not have occurred if the elders of the churches had remained true to the Bible, and united in carrying out their responsibilities according to God's Word. The same is true today. As a rule, as the leadership goes, so goes the church.
