Since the authority of civil law is relevant here, and is so relevant that this is immediately apparent rather than requiring some hidden reasoning, a few things must also be said about it. Knowledge of law and legislation is undoubtedly a sound discipline of morals and life. Philosophy is the law and rule of life; therefore those skilled in civil law must be considered philosophers, if they profess what he calls true philosophy. The first argument that civil law can in no way help theologians is that priests, and even monks, are forbidden to study such laws. That discipline, which canonical law prescribes clerics to shun, therefore conflicts with theology. Further, theology concerns divine things, while civil law deals with the administration of human and temporal things; it is scarcely conceivable what use the knowledge of temporal administration could provide a theologian discussing eternal matters. Cyprian admits that pontiffs use imperial laws, but only in the course of temporal affairs. Therefore, when ecclesiastical men wish to treat theological—that is, divine and everlasting—matters, they ought not to use imperial laws. The enactments of emperors, which make up civil law, sometimes also oppose God’s laws. A theologian therefore will not receive from them any suitable argument to establish theological conclusions.
