The office of deacons was established in the early church (Acts 6:1-7), since there was a need to attend those in need as the church grew.
The ministry of deacon as set forth in Scripture is one of compassion, witness, and service, sharing in the redeeming love of Jesus Christ for the poor, the hungry, the sick, the lost, the friendless, the oppressed, those burdened by unjust policies or structures, or anyone in distress. Persons of spiritual character, honest repute, exemplary lives, brotherly and sisterly love, sincere compassion, and sound judgment should be chosen for this ministry.
(The Presbyterian Church (U.S.A.) Book of Order)
And do not forget to do good and to share with others,
for with such sacrifices God is pleased
Each of you should look not only to your own interests,
but also to the interests of others.
