St. Justin was a philosopher and martyr who was born of pagan parents at Flavia Neapolis in Samaria at the beginning of the second century. Following his conversion, he wrote many works in defense of Christianity. Those two works are the Apology and the Dialogue with Trypho.
The writings of Justin contain some of the earliest descriptions of the Mass. Justin used reason to win over many people to Christianity. He dedicated his life to searching for the Truth and found the Truth in following the ways of Jesus. During his life, Justin opened a school in Rome where public debates were held.
Justin was martyred with several companions around the year 165 during the reign of Marcus Aurelius.
