And although I know, dearest brother, from the mutual love which we owe and manifest one towards another, that you always read my letters to the very distinguished clergy who preside with you there, 1 and to your very holy and large congregation, 2 yet now I both warn and ask you to do by my request what at other times you do of your own accord and courtesy; that so, by the reading of this my letter, if any contagion of envenomed speech and of pestilent propagation has crept in there, it may be all purged out of the ears and of the hearts of the brethren, and the sound and sincere affection of the good may be cleansed anew from all the filth of heretical disparagement.
