Just my thoughts from study of this from several points of view. The position of a Pastor as we have today is not scriptural period. Pastors were gifting's given to the church as per
Ephesians 4 This is the only place pastor is found in all the NT. And they were only part of a four fold gifting to the church to equip the saints to do the work of ministry.
Deacons and Elders were not pastors, and they were chosen by others based upon their life that was proven beforehand that they were qualified to be in said positions.
