I know, you don’t believe me. But here it is. Look it up for yourself. Calvin wrote the letter which contains these lines on 14 October, 1543-
I understand very well the difficulty in which you are placed if you look to the world, and those considerations which may keep you back. But you will need to come to a settled conclusion, to cast aside everything which shall come in the way to cross you in your purpose. One ought not, it is true, to take such a step at random, that is to say, without foundation, and without knowing why or wherefore. But when you have your conscience assured by a testimony which is better and stronger than all the world could give you, you ought to acquiesce therein out and out, and deem besides, that all the obstacles which interpose to divert or turn you aside, are scandals which Satan lays before you to block up the way. Howbeit, to my thinking, there is no great need to allege many reasons to shew you what to do according to the word of God. I take it for granted, that you are already clear upon that point.
— John Calvin
