He also recognises the various grades of the hierarchy, priestly and episcopal Orders. “The Church is a general hospital for healing those who are spiritually sick”;[579] the rules which she gives to the clergy, the recital of the Divine Office for instance, must be obediently carried out.[580] She has a right to temporal possessions, only “at the present day almost all declare these to be spiritual things; they, the clergy, are masters in this ‘spiritual’ domain and are more careful about it than about their real spiritualities, or about their use of thunderbolts [excommunications] in the sentences pronounced by the Church.”[581] According to him, the prelates and the Church have a perfect right to condemn false teachers however much the latter may “utter their foolish cry of ‘we have the truth, we believe, we hear, we call upon God.’” “Just as though they must be of God because they seem to themselves to be of God. No, we have an authority which has been implanted in the Church, and the Roman Church has this authority in her hands. Therefore the preachers of the Church, unless they fall into error, preach with assurance [on account of their commission]. But false teachers are pleased with their own words, because they are according to their own ideas. They appear to demand the greatest piety, but are themselves governed by their own opinion, and their self-will.”[582] “Whoever declares that he is sent by God must either give proof of his mission by wonders and heavenly testimony, as the Apostles did, or he must be recognised and commissioned by an authority confirmed by Heaven. In the latter case, he must stand and teach in humble subjection to such authority, ever ready to submit to its judgment; he must speak what he is commissioned to speak and not what his own taste leads him to invent.... Anathema is the weapon,” he exclaims—unconscious of his own future—“which lays low the heretics.”[583]
