I had just started in a youth pastorate in Montana. My senior pastor and mentor was talking about taking one other young guy, myself, and he to breakfast once a month for mentoring and study. He chose to have us read Calvin's Institutes. The Battle's translation. A big, two-volume behemoth. The tome cost me over $50 dollars. "I know it is expensive," he said, "but you have to do it." So I did.
