Our context...
Is there a Biblical precedence for vocational pastors who take a salary from their congregations? I'm kind of noticing how paid pastors tend to be the lynchpin that hold the entire institutionalized, corporate/business model church system together.
Given this, I will tell you from the NT how they did it and what scripture says about the roles and how this is better than the way churchianity does it and the problems the one-man system leads to. My implicit bias is I think the apostles did things a certain way for a reason and I've seen plenty in history to believe that is true.
That is not to say I'm condemning you to hell for doing it differently, I'm just sharing the Biblical model. Whether it is wrong or sinful to do it a different way is an entirely different question outside the bounds of this discussion (its just too complex to go into here and I don't have a definitive answer to give). 'Its not sinful to do it different' isn't really a defense on the question of how the first apostles and their churches did it.
But I will tell you, in light of history, the scriptures and what we know about gifting and personalities. that it is very unwise to do it differently.
Nor is this just an unprofitable debate over words. I'm not insisting on any certain title. I could care less what title folks use. For example, most denominations have apostles still, they just call them missionaries or church planters. Whatever. But I do use the scriptural titles for clarity and specificity when talking about the roles and gifts lined out in scripture and how those contrast with common practice today.
There is great spiritual and practical utility in understanding how the first Christians did things; especially when one is coming together in a new fellowship and wondering how to go about things. Words mean things and the scriptures were given for a reason. Many of the problems we see today are a direct result of doing things differently than they were done by the first Christians. Whatever path you take should be entered into with eyes wide open in light of all that we know and not just because 'that is how it is always done'.
Be wary of putting new wine in old wineskins; I've seen that destroy new fellowships.
But neither is this the most important thing in a new fellowship. For that, go read the concluding chapters of John where Jesus talks about loving one another.
