Until now I have only used books and sermons to wean the hearts of people from their godless regard for ceremonial… For I have been hesitant and fearful, partly because of the weak in faith, who cannot suddenly exchange an old and accustomed order of worship for a new and unusual one, and more so because of the fickle and fastidious spirits who rush in like unclean swine without faith or reason, and who delight only in novelty and tire of it as quickly, when it has worn off. Such people are a nuisance even in other affairs, but in spiritual matters, they are absolutely unbearable. Nonetheless, at the risk of bursting with anger, I must bear with them, unless I want to let the gospel itself be denied to the people.
