Deacon
8 Deacons, likewise, should be worthy of respect, not hypocritical, not drinking a lot of wine, not greedy for money, 9 holding the mystery of the faith with a clear conscience. 10 And they must also be tested first; if they prove blameless, then they can serve as deacons.
1 Timothy 3:8-10 NLT
Deacons are required to be mature Christians. These verses list attributes of a mature Christian (not just deacons); and not being greedy for money is one of them.
