Wonderful, let you and I debate. First, where in the Bible is there an "office" of a pastor? Can you show me anywhere in the Bible where the word ποιμένας is used for anything other than a herder of sheep (other than the Great Shepherd)? IF the Holy Spirit appointed Elders and gave them the work of shepherding and overseeing the Church then where are they today? Why have they been replaced with someone called a "pastor?" We will start with these questions. Thank you for offering a debate.
Well, the elders of the churches in Paul's time are dead today. Secondly, where did you get the idea that the Holy Spirit appointed elders of the local churches? Acts 14:23 states that Paul and Barnabas appointed elders.
God has used one person throughout the Bible to lead his people such as Moses, David, Joshua, etc. When Paul writes Timothy, he writes to him alone, not to the collection of elders. That means Timothy was charged with leading the church.
1 Timothy 5:17 and 1 Cor 9:6-14 talks about elders that were paid. One way or another, the New Testament contemplates some leaders who are set aside by the church to be paid to do the work of preaching and teaching.
Finally, common sense dictates that if there is a group of elders or pastors, one will emerge as the leader. If you have ever been on jury duty, it becomes apparent who the leader is very quickly.
The final point is, the way you have debated with others over such a minor issue proves nothing. The bottom line is, each local church decides for itself the form of government.
