I know this denomination and church appear to have their problems, but for a good Reformed pastor I don't think any salary is too high. I am grateful for all the pastors of my churches over the years. I know many of them live on meager income and give back a substantial portion of that - I would increase their salaries 10-fold if I could.
And $250,000 is reasonable by NYC standards, but not great. Sure, a crummy, tiny studio in the Village may be $1500 a month, but any decent lodging appropriate for a family will run at least $3500/month in Manhattan.
