Abstract
Statement of the Thesis|1. Conversion of Justin marked a new era in gospel history because the intellectual enemies of the faith were met.|2. Justin's knowledge of Plato helped him to encounter the philosophers of the day.|3. His knowledge is revealed through a study of the most important work The Dialog with Trypho.|a. This is shown by direct reference to Plato b. and by expression of ideas similar to those of Plato.|Conversion of the learned philosopher, Justin, whose writings became the foundation of theological literature, marked a new era in gospel history, for his knowledge of pagan philosophy made it possible for him to answer the arguments of the philosophers of the day, who, because intellectually reputable, provided Christianity with its most serious opponents.
