Roman Catholics, Eastern Orthodox, and Protestants consider that the 2nd century Justin, who was martyred, a saint and an important early Christian writer. Yet, Justin wrote against some doctrines they hold too and for some doctrines they do not hold to. What did Justin teach on issues such as military service, the immortality of the soul, going to heaven upon death, idols, the millennium, the eighth day, the illumination, Christians who kept the Sabbath, etc.? Should Christians consider him to have been a saint or an apostate? Dr. Thiel addresses these matters, quotes papers by Justin, and also quotes numerous scriptures.
