Oration of Gregorio de Valencia,

pestilential and venomous speech crawls like a cancer. Therefore, what we see practiced today in the Church, so that teachers are constituted primarily by ecclesiastical authority as if by divine disposition (which is done in our own and other Catholic universities), this same thing has always been held as solemn by our ancestors. From this common custom and practice, Eusebius also records that Origen was constituted a teacher in the Alexandrian school not by himself, but by the Bishop. Book 6, History, chapter 3. "Therefore," he says, "Origen, with the office of master enjoined upon him by Bishop Demetrius, began to neglect the school of grammar, giving himself more to the explanation of the word of God." Nor does it seem necessary for me in this oration, which I undertake against the disciples of Luther, to prove that accurately, which they themselves cannot deny, and which Luther himself has easily confessed to his own and his followers' detriment. For interpreting those words of the Apostle, "Paul an Apostle, not from men, nor through man," he says, "Everything tends toward this, that you may see with what care God instituted and fortified his Church, lest anyone should presume to teach rashly, unless he is sent by Him, or by those sent by Him." In Commentaries on the Epistle to the Galatians. Galatians 1.
