Pastor"A pastor is the leader of a Christian congregation who also gives advice and counsel to people from the community or congregation. In Protestantism, pastor may be ordained or not (even a layperson may serve in this capacity) while in the Catholic Church and Orthodox Churches, the pastor is always an ordained priest. Pastors are to act like shepherds by caring for the flock, and this care includes teaching. The New Testament typically uses the words “bishops” (Acts 20:28) and “presbyter” (1 Peter 5:1) to indicate the ordained leadership in early Christianity. Likewise, Peter instructs these particular servants to “act like shepherds” as they “oversee” the flock of God (1 Pet. 5:2). The words “bishop” and “presbyter” were sometimes used in an interchangeable way, such as in Titus 1:5-6. However, there is ongoing dispute between branches of Christianity over whether there is two ordained classes (presbyters and deacons) or three (bishops, priests, and deacons). In traditional Christianity (the Catholic Church, Orthodox Church, and Oriental Orthodox Church) bishops, priests and deacons are recognised who have been ordained with apostolic lineage. In most Protestant denominations, in contrast, bishops are rejected, as well as the doctrine of apostolic succession." - (en.wikipedia.org 01.03.2020) Geistlicher
