Elders
Elders must watch diligently over the flock committed to their charge, that no corruption of doctrine or of morals enter therein. They must exercise government and discipline, and take oversight…of the spiritual interests of the…church. 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. (PCA Book of Church Order, paragraph 8-3.)
Deacons
Deacons minister to those 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. (PCA Book of Church Order, paragraph 9-2.)
