According to Paul, it was only Barnabas and himself who had to support themselves (v6). It would seem that the other Apostles did not need to support themselves. They even took their wives with them on their trips.
In 1 Cor 9, Paul makes it clear that the norm is that those in Christian ministry are paid, and do not have to support themselves (v7, v9, v14).
14 In the same way, the Lord has commanded that those who preach the gospel should receive their living from the gospel.
There is room for both, just as in NT times.
Here (England), Baptist ministers/pastors receive a stipend, not a salary. A salary is paid for the duties performed. A stipend is paid to enable someone to serve without needing to spend time working in a paid job. Subtle difference.
2Timoth2:15's experience might be typical of America (I hope not), but is far from my, albeit limited, experience in England. Those pastors and ministers that I know serve from a strong sense of calling. It is not 'just a job'. But in reality, that should apply to all of us, whether we are in 'full time secular' employment, or 'full time Christian' work. Or a mixture.
1 Corinthians 9 in context is not endorsing a full time paid pastor. Also, we know that mark and luke were in the same city more than once with Paul and we know they were still alive. Yes, all the apostles worked.
1 Thessalonians 2King James Version (KJV)
2 For yourselves, brethren, know our entrance in unto you, that it was not in vain:
2 But even after that we had suffered before, and were shamefully entreated, as ye know, at Philippi, we were bold in our God to speak unto you the gospel of God with much contention.
3 For our exhortation was not of deceit, nor of uncleanness, nor in guile:
4 But as we were allowed of God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, which trieth our hearts.
5 For neither at any time used we flattering words, as ye know, nor a cloke of covetousness; God is witness:
(they did not take salaries) not just Paul
6 Nor of men sought we glory, neither of you, nor yet of others, when we might have been burdensome, as the apostles of Christ.
7 But we were gentle among you, even as a nurse cherisheth her children:
8 So being affectionately desirous of you, we were willing to have imparted unto you, not the gospel of God only, but also our own souls, because ye were dear unto us.
9 For ye remember, brethren, our labour and travail: for labouring night and day, because we would not be chargeable unto any of you, we preached unto you the gospel of God.
They all were working to provide for themselves labouring night and day. Why so they would not be chargeable to ANY of you - meaning no one owed them a salary nor did they expect it.
How is it that there is SO much evidence of this in scripture, not just Paul not charging but all the Apostles yet it is totally ignored by the hirelings today who simply want to justify their salaries.
10 Ye are witnesses, and God also, how holily and justly and unblameably we behaved ourselves among you that believe:
1 Thessalonians 4
9 But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.
10 And indeed ye do it toward all the brethren which are in all Macedonia: but we beseech you, brethren, that ye increase more and more;
11 And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
Why is Paul telling them to work with their hands? Because this is the model, the model he is doing through example and what he expects. Why...verse 12 tells us.
12 That ye may walk honestly toward them that are without, and that ye may have lack of nothing.
Walking honestly = working and providing for yourself and others, just as Paul, Barnabas, Timothy, and Titus ALL did
2 Thessalonians 3
7 For yourselves know how ye ought to follow us: for we behaved not ourselves disorderly among you;
8 Neither did we eat any man's bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you:
9 Not because we have not power, but to make ourselves an ensample unto you to follow us.
10 For even when we were with you, this we commanded you, that if any would not work, neither should he eat.
There it is Paul was not just simply foregoing some false right to a salary he explains CLEARLY - all should work, including pastors.
