meaning different from Pastor and Minister?

Pastor中文是牧師
而Minister中文是傳道人
那麼牧師和傳道人有甚麼分別呢？
其實兩者都是從事牧養教會信徒的工作，但牧師是要經過一個按牧的儀式後，才成為牧師；傳道人則毋須經過這儀式。
至於工作方面，有些教會兩者是沒有分別的；但有些教會有些禮儀就必須牧師主持，如聖餐、浸禮和喪禮等。
希望這樣簡單的解釋你會明白！

A pastor is an Elder of a Christian church The word itself is derived from the Latin word pastor which means shepherd. Pastor, shepherd and elder are the same, but are not synonymous with preacher or minister.

Minister can mean several things:
Minister (government), a politician who heads a government ministry.
Minister (Christianity), a Christian who ministers in some way.
Minister (diplomacy), the rank of diplomat directly below ambassador

In general. Pastor is used more often in Christian church while minister could be a non- christian.

I hope it helps.
