In Calvin’s treatise called “God’s Eternal Predestination and Secret Providence” (an awesome piece of writing!) the Reformer continually calls his readers to stay within the limits of what God has revealed to us concerning predestination and providence. Here’s one of the more memorable lines (one of many):
“Those who seek to know more than God has revealed are madmen.”
He uses Augustine several times to reiterate the point. Here’s one quote of Augustine he used.
“When men ask us why God did this or that, our answer is to be, ‘Because it was his will.’ If they go on to inquire, Why did he so will it? our reply should be, ‘Now you ask what is greater and higher than the will of God itself. You ask what none can find out.’ Let human rashness, then, keep itself within bounds. Let it never seek after that which is not, lest it should not find that which is.”
One more by Calvin:
“Into this mirror [Christ] let the eye of our faith ever fixedly look. Let it not desire to penetrate where access to its sight is not given.”
I always love this emphasis by Augustine and Calvin. It is easy for knowledge-seekers to go where we should not go – we need constant reminders to stay within the limits of scripture, and stay humbly there. It really means staying at the feet of Jesus, the sum and substance of scripture. Wise Christians will not be afraid to say “I do not know” when asked certain deep questions. This is part of the epistemological humility that we should pray for and seek to exhibit.
