not a drinker, not violent, not greedy for money, but gentle, not quarrelsome, not covetous;
These two Greek words refer to the same office and people. For example (in the words of the RSV), in Acts 20:17 Paul sent for the elders (presbuteroi) of the Ephesian church, but in verse 28 he called them guardians (episkopoi). Likewise in Titus 1:5 he told Titus to appoint elders (presbuteroi), then in verse 7 he called them bishops (episkopoi). Elders were like shepherds over the flock. Their responsibility was to lead, rule, guide, teach and care for the church (Acts 20:28; 1 Timothy 3:5; 1 Timothy 3:5; 1 Timothy 5:17; Hebrews 13:17; 1 Peter 5:1-3; 1 Peter 5:1-3).
