Introduction.

Justin, as is known, became a Christian around the thirtieth year of his life, and one is struck by the vast scope of his knowledge and his correct understanding of the prophetic books, even in those of his works which he published a short time after his conversion; such as, for example, his Apology addressed to the Emperor Antoninus, and his Dialogue with Trypho the Jew. This latter work especially is a masterpiece of its kind for using prophecies to prove everything concerning the divinity of Jesus Christ, and for bringing to light the truth of the mysteries of his life, his actions, and his eternal kingdom through the establishment of his religion.

The learned Theophilus of AntiochTheophilus (died c. 183 AD) was a bishop who wrote extensively to defend Christianity against paganism, emphasizing the historical continuity of the Hebrew prophets. demonstrates in his third book to AutolycusAutolycus was a pagan friend of Theophilus whom he sought to convert through these writings. the wonderful harmony between the prophets, regarding both historical facts and moral teachings, from Moses down to Malachi, or across nearly twelve hundred years. Clement of AlexandriaTitus Flavius Clemens (c. 150–215 AD), a theologian who sought to unite Greek philosophy with Christian doctrine. gives the most important and moving instruction in his Instructor (or Paedagogus) and in his collections—the Stromataoriginal: Stromata — a Greek word meaning "miscellanies" or "tapestries," used by Clement to describe his wide-ranging collection of notes on Christian life and philosophy.—and the divine books are always the source from which he draws his lessons and observations. In most of his treatises, Saint Cyprian introduces Jesus Christ, the apostles, and the prophets as if they were speaking directly. What use did TertullianTertullian (c. 155–220 AD) was a prolific early Christian author from Carthage, often called the "father of Latin Christianity." not make of the divine Word in all his polemics against the heretics, against the philosophers, and the heathens? And what shall we say of the renowned OrigenOrigen of Alexandria (c. 184–253 AD) was one of the most influential figures in early Christian theology and biblical exegesis., who [studied] the Holy Scripture in all languages and in all translations
