Will wonders never cease? Calvinists who act like Jesuits!?
Seriously, if you are fundamentally convinced that
a) Calvinism is Truth and Arminianism is Error,
and that
b) local churches need to be brought out of Error into Truth
and that
c) God has not only elected you to salvation but called you to the task
and that
d) there's no way this lapsed church would hire you if you told them the Truth up front
then how on earth are you supposed to act? Didn't God bless Jacob (and diss Esau) for tricking his dad?
