This is the source of the problem -- "the pastor". Most evangelical and fundamental churches ignore the actual New Testament teaching on pastor/elder/bishops. There was always a PLURALITY OF ELDERS in all the NT churches.
For this cause left I thee in Crete, that thou shouldest set in order the things that are wanting, and ordain elders [PLURAL] in every city, as I had appointed thee: (Tit 1:5)
God never intended one man to shoulder the responsibility of shepherding a flock of Christians, just as Moses was encouraged to appoint elders to shoulder that responsibility in Israel. And it is in this context that Paul writes about giving *double honour* to those elders who LABOR in the Word and doctrine. So some elders would earn their own living while others would devote their full time to the ministry of the Word. But they would not be seminary graduates, but mature Christian men from within the assembly (as we see in Titus 1:5). Therefore compensation to preachers and evangelists is according to Scripture, for those who preach the Gospel must also live off the Gospel.
But here is what this OP is focused on -- "not for filthy lucre (money)": Feed the flock of God which is among you, taking the oversight thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind (1 Pet 5:2) [Note: Money is not filthy per see, but when it is associated with greed, it becomes filthy]
So God already warned pastors that their ministry was NOT TO BECOME WEALTHY but to feed the flock with spiritual food, and tend the sheep on a personal basis by "taking the oversight thereof". And oversight refers to elders (presbuteros) being bishops or overseers (episkopos). Thus pastors were elders and elders were bishops, but it was always a group of men, not one man trying to do everything (as generally found today).
