I am now engaged on the refutation of Luther's book, which refutation you will see about September 1st. I am indeed wholly averse to this kind of fighting; but what do they think is to be done by him who is attacked with edge and point? Do not all believe that in repelling an enemy he is to be kept away, and if this is to be accomplished in no other way, he is to be cut down? And must we not oppose engines to those battering-rams which caus enot theology but faith adn truth to be overthrown, friendship to perish, and whatever is sacred and in moderation to be held in contempt among mortals? That book of Luther's, what else is it than an example of denying what you a little while ago? or a fog through which you cannot see rightly the mystery of Christ? I shall put forth nothing wild against Luther - a thing hehimself ought not to have done. Since he has done it I shall remember piety and Christian decorum.
