Definitions: In Latin, the word for shepherd is "pastor". In English, "pastor" is generally used to mean a clergyman or preacher. However in the scriptures it refers exclusively to the shepherds (elders) of a congregation, not the preachers or evangelists.

There are four Greek words rendered by seven English words. Here are the Greek, English, Strong's reference, and scripture examples
Comment: In the above table, the Greek/English equivalents are given. Some translators, instead of the simpler English, use the words in brackets. Personally, I think the bracketed words (bishop, pastor, presbyter) are less suitable for general use in the church, because they need too much explaining and can be misleading because of denominational usage.
