It is the duty of the deacons to minister to those who are 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 oversee the finances of the church. They shall have the care of the property of the congregation, both real and personal, and shall keep in proper repair the church building and other buildings belonging to the congregation.
