When God sees this perverted state of affairs, He perverts it still more, as is written in Psalm xviii[34], "With the perverse thou wilt be perverted" [Ps. 18:26]; and He brings it to pass that they make themselves and their brotherhoods a mockery and a disgrace, and He casts them out from the common brotherhood of saints, which they oppose and do not make common cause with, into their brotherhood of gluttony, drunkenness and unchastity, so that they, who have neither sought nor thought of anything more than their own, may find their own; and then He blinds them that they do not recognize it as an abomination and disgrace, but adorn their unseemliness with the names of saints, as though they were doing right; beyond this He lets some fall into so deep an abyss that they openly boast and say whoever is in their brotherhood cannot be condemned, as though baptism and the sacrament, instituted by God Himself, were of less worth and were less certain than that which they have thought out with their darkened minds. Therefore their God will dishonor and blind those who, with their mad conduct and the swinish practices of their brotherhoods, mock and blaspheme His easts, His name, and His saints, to the injury of the common Christian brotherhood, which flowed from the wounds of Christ.

4. Therefore, for the right understanding and use of the brotherhoods, one must learn to distinguish rightly between brotherhoods. The first is the divine, the heavenly, the noblest, which surpasses all others, as gold surpasses copper or lead--the fellowship of all saints, of which we spoke above[35]. In this we are all brothers and sisters, so closely united that a closer relationship cannot be conceived, for here we have one baptism, one Christ, one sacrament, one food, one Gospel, one faith, one Spirit, one spiritual body, and each is a member of the other; no other brotherhood is so close. For natural brothers are, to be sure, brothers of one flesh and blood, of one heritage and home, but they must separate and join themselves to others' blood and heritage[36]. Organized brotherhoods have one roll, one mass, one kind of good works, one festival day, one treasury, and, as things are now, their common beer, common feast and common debauch, but none of these binds men so closely together as to produce one spirit, for that is done by Christ's brotherhood alone.
