And yet in many congregations, ministers have the best compensation package. I would love to see a fuller conversation of compensation and financial wellness for all who work in churches. Yes, as a religious educator, I've got an interest here. But it's also about our music directors, administrative staff, sextons--whatever positions make up each congregation.
Sure, many (but not all) of these folks haven't been to seminary, but that doesn't mean that they aren't carrying student loans, or that they don't have their own formation expenses which may or may not have been covered by a congregation. And with no faith requirement in most of these positions*, we cannot be expecting a vow of poverty.
Theologically, economic justice needs to be practiced in our houses of worship.
The Unitarian Universalist Association's Office of Church Staff Finances has done considerable work. Fair compensation guidelines including not just salary, but parity of benefits, and a full listing of best practices.
It's a pretty strong list, and the office has different levels of recognition for congregations to strive toward.
*My experience is with Unitarian Universalist congregations. Other churches/denominations may have a faith statement.
