In the epistle to the Colossians the title for a "Pastor", is "Minister". No need of others proofs, is evident
Colossians 1:7 As ye also learned of Epaphras our dear fellowservant, who is for you a faithful minister of Christ;
Therefore Epaphras was the "Minister" of the Colosse Church.
A Minister is teaching and is pastoring the church but we cannot call him a rabbi, prophet or master. In the same way we cannot call him a pastor, father or a priest. There are no pastor or priest in the New Testament.
To be a Minister, a Servant of God what a biblical blessed name.
If we identify the church as a flock, the believers are the sheep and the Lord is the Shepherd, the Pastor.
There are only one Pastor that give is life for the sheep.
