If a local body decides to pay a pastor a salary, then a large portion of the money taken in is already gone. A pastor's "package" may cost the church $50,000 per year (maybe more, maybe less). That means that the believers in that church have to give over 50 grand for any money to go toward anything else.
Of course, a local body that pays a pastor likely also has to pay for a large building. There goes the next massive chunk. So before any money can be spent on anything else, the pastor and the mortgage company must be paid.
The simple math is that if a church pays a pastor a salary, then it has far less money to give to those who truly need it: the poor and needy. When we look in the bible, we see numerous exhortations to care for those who are unable to care for themselves. We see in scripture the church give its money away to those who have little to no means of making money of any kind. The poor and needy can be those inside the church or outside.
The sick irony is that most pastors are, in fact, quite capable of working real jobs to support themselves and their families. They do not qualify as "the poor and needy." I quit as a professional pastor and have held down a regular job for four years. It is not, as they say, "rocket science."
Professional pastors ought to all resign immediately because they are keeping money from going to the poor and needy. It is as simple as that.
