Faith is always coveted most and needed most urgently where will is lacking; for will, as the affect of command, is the decisive sign of sovereignty and strength. In other words, the less one knows how to command, the more urgently one covets someone who commands, who commands severely—a god, prince, class, physician, father confessor, dogma, or party conscience. From this one might perhaps gather that the two world religions, Buddhism and Christianity, may have owed their origin and above all their sudden spread to a tremendous collapse and disease of the will. And that is what actually happened: both religions encountered a situation in which the will had become diseased, giving rise to a demand that had become utterly desperate for some "thou shalt." Both religions taught fanaticism in ages in which the will had become exhausted, and thus they offered innumerable people some support, a new possibility of willing, some delight in willing. For fanaticism is the only "strength of the will" that even the weak and insecure can be brought to attain, being a sort of hypnotism of the whole system of the senses and the intellect for the benefit of an excessive nourishment (hypertrophy) of a single point of view and feeling that henceforth becomes dominant— which the Christian calls his faith. Once a human being reaches the fundamental conviction that he must be commanded, he becomes "a believer."Conversely, one could conceive of such a pleasure and power of self-determination, such a freedom of the will [ This conception of "freedom of the will" ( alias, autonomy) does not involve any belief in what Nietzsche called "the superstition of free will" in section 345 ( alias, the exemption of human actions from an otherwise universal determinism).] that the spirit would take leave of all faith and every wish for certainty, being practiced in maintaining himself on insubstantial ropes and possibilities and dancing even near abysses. Such a spirit would be the free spirit par excellence.
There are some who are still weak in faith, who ought to be instructed, and who would gladly believe as we do. But their ignorance prevents them...we must bear patiently with these people and not use our liberty; since it brings to peril or harm to body or soul...but if we use our liberty unnecessarily, and deliberately cause offense to our neighbor, we drive away the very one who in time would come to our faith. Thus St. Paul circumcised Timothy (Acts 16:3) because simple minded Jews had taken offense; he thought: what harm can it do, since they are offended because of ignorance? But when, in Antioch, they insisted that he out and must circumcise Titus (Gal. 2:3) Paul withstood them all and to spite them refused to have Titus circumcised... He did the same when St. Peter...it happened in this way: when Peter was with the Gentiles he ate pork and sausages with them, but when the Jews came in, he abstained from this food and did not eat as he did before. Then the Gentiles who had become Christians though: Alas! we, too, must be like the Jews, eat no pork, and live according to the law of Moses. But when Paul learned that they were acting to the injury of evangelical freedom, he reproved Peter publicly and read him an apostolic lecture, saying: "If you, though a Jew, live like a Gentile, how can you compel the Gentiles to live like Jews?" (Gal. 2:14). Thus we, too, should order our lives and use our liberty at the proper time, so that Christian liberty may suffer no injury, and no offense be given to our weak brothers and sisters who are still without the knowledge of this liberty.
