Calvinists and non-Calvinists here, methinks, should be this (taken from the preface in "Against Calvinism")
"At the end of the day, Roger (Olson, Arminian) and
I (Michael Horton, Calvinist) share the most important agreement: namely, that the crucial questions involved in this or any other debate must be brought to the bar of
scripture. We both believe that scripture is clear and sufficient, even if
we are confused and weak. We are all pilgrims on the way, not yet those
who have arrived at our glorious destination. Only by endeavoring more
and more to talk to each other as coheirs with Christ instead of about
each other and past each other as adversaries can we engage with serious
disagreements—and with the hope that we may also be surprised by
felicitous agreements along the way."
