Quintus Septimius Florens Tertullianus (born ca. 150-160, died ca. 220-240) A major theologian in the early Christian church, known for his powerful denunciations of many influences he considered heretical, including the widespread admiration of pagan philosophers and many Gnostic ideas, yet in later life a Montanist, and thus he himself an embracer of beliefs that came to be declared heretical.

• Quippe res dei ratio quia deus omnium conditor nihil non ratione providit disposuit ordinavit, nihil [enim] non ratione tractari intellegique voluit. [3] Igitur ignorantes quique deum rem quoque eius ignorent necesse est quia nullius omnino thesaurus extraneis patet. Itaque universam vitae conversationem sine gubernaculo rationis transfretantes inminentem saeculo procellam evitare non norunt.
  • Translation: Reason, in fact, is a thing of God, inasmuch as there is nothing which God the Maker of all has not provided, disposed, ordained by reason— nothing which He has not willed should be handled and understood by reason. All, therefore, who are ignorant of God, must necessarily be ignorant also of a thing which is His, because no treasure-house at all is accessible to strangers. And thus, voyaging all the universal course of life without the rudder of reason, they know not how to shun the hurricane which is impending over the world.
