"Deacons likewise must be dignified, not double-tongued, not addicted to much wine, not greedy for dishonest gain. They must hold the mystery of the faith with a clear conscience.  And let them also be tested first; then let them serve as deacons if they prove themselves blameless.  Their wives likewise must be dignified, not slanderers, but sober-minded, faithful in all things.  Let deacons each be the husband of one wife, managing their children and their own households well.  For those who serve well as deacons gain a good standing for themselves and also great confidence in the faith that is in Christ Jesus."
1 Timothy 3:8-13
