Phoebe: Minister of the Word

What did Paul mean when he used the word for โ€œdeaconโ€ and the word for โ€œbenefactorโ€ but also โ€œchurch officialโ€ (in the Septuagint) in association with Phoebeโ€™s service to Paul and to the Body of Christ? What was Paul assuming his readers would already know and understand, so it went without being said?

Phoebe

Paul introduced her as โ€œour sister,โ€ and later one of the saints. Phoebe was deacon of the church at Cenchreae, and she was to be warmly welcomed. Anything she required, the assemblies in Rome were to provide for her. Why? Because she was, in fact, a benefactor of many, including Paul himself.
