Well I’m not a Calvinist and you guys have the freedom to believe what you want to believe.
Calvinism teaches something like this: everything we do is predetermined, including having faith in God. This means we have no free will to choose faith.
Mainstream Christianity supports the existence of free will.
Back to the discussion. Pence, like Christians in general, knows he needs to enter not into temptation. So the right conclusion is that his practice of not being alone with women shows he is among the most trustworthy.
