29 What shall I answer hereafter, if it be discovered that, by authority given from this place, Christians have been slain by the sword, or by clubs, or thongs knotted with lead? How shall I explain such a fact? How shall I excuse it to those bishops, who now mourn bitterly because some, who have discharged the office of the priesthood for thirty and many more years, or other ministers of the Church, are withdrawn from their sacred office, and set to discharge municipal duties? For if they who war for you serve for a stated time of service, how much more ought you to consider those who war for God. How, I say, shall I excuse this to the bishops, who make complaint concerning the clergy, and write that the Churches are wasted by a serious attack upon them?
