Are there bishops in the Bible?

1. Bishops and Elders are the same thing. In the KJV,  the Greek word "episkopos" is translated bishop (AV 1 Timothy 3:1, Philippians 1:1) or overseer (Acts 20:28) and the word "presbyteros" is translated elder (Acts 15:2; 20:17, Titus 1:5, 1 Peter 5:1 etc).  A look at Titus 1:5-7 and Acts 20:17 & 28 shows that both words refer to the same thing. 1 Peter 5:2 shows that the elders took the "oversight" (Greek: epikopountes). The idea of elders would have been familiar to Jewish Christians as the synagogues were already governed by a body of elders and the Old Testament often refers to elders. The name overseer is more descriptive of the work of elders and would perhaps convey more to Gentile readers. We can conclude that Biblical bishops were not a higher office with authority over several local churches and their officers, though the term is used in that hierarchical sense today.

2. All elders are pastors or shepherds. The elders are to "feed" or to "shepherd" the flock of God (Acts 20:28, 1 Peter 5:2). They are to care for the flock as those acting under Christ, the Chief Shepherd and Bishop (or Overseer) of our souls (1 Peter 2:5 and 5:4).

3. Every congregation should have bishops/elders. Elders existed in Jerusalem, Philippi, Ephesus and Crete (Acts 15:2, 20:17, Phlippians 1:1, Titus 1:5). Their presence was the norm and there was more than one in each congregation.

4. Some Elders are Ministers of the Word. Paul tells Timothy "let the elders that rule well be counted worthy of double honour especially they that labour in the word and doctrine" (1 Timothy 5;17). This indicates that some elders as well as ruling and governing the church along with the others, also have the particular task of preaching the word of God. So Romans 12:7-8 distinguishes between "teaching" and "ruling". The gifts mentioned in 1 Corinthians 12:28 include "teachers" and "governments". In Ephesians 4:11 there are those who are pastors and teachers (ie shepherds/elders and also teachers of the word).The word "minister" is applied in the New Testament to various kinds of service including the ministry of the word (Ephesians 3:7, Colossians 1:7, 1 Thessalonians 3:2, 1 Timothy 4:6). With the discontinuation of the foundational teaching of offices of apostles and prophets, the general term is usually applied to the teaching elders. Nevertheless, apart from the ministry of the word all the elders are equally responsible to "watch for souls" (Hebrews 13:17) and accountable for their stewardship.
