St. Justin was born circa 103 AD in Neapolis, Samaria, modern-day Palestine. He studied the teachings of Plato and Socrates; and several of his apologetics works are extant. St. Justin converted during adulthood; and God drew him closer through the Church and the working of the Holy Spirit.
One day, St. Justin meditated on the thought of God by the seashore. He encountered an elderly gentleman who shared the Gospel. St. Justin, hearing about Jesus Christ and the Church, received the gift of faith.
By praying, reading Holy Scripture and witnessing the constancy of Christian martyrs, St. Justin's faith in Jesus Christ grew mighty. He preached the Gospel in Greece, Egypt and Italy. He leveraged his knowledge of philosophy to reflect the light and image of Christ. He established a school in Rome, where he was accused by envious philosophers and put to death during the reign of Marcus Aurelius.
