Justin Martyr (c. 100 - c. 165) was one of the earliest of the Apologists, spokesmen who offered an apologia
, a reasoned defense of Christianity (Acts Acts 22:1
; 1Pe. 1Pe. 3:15
). Justin studied philosophy prior to his conversion to Christ. In his Dialogue with Trypho
he attempts to explain to a Jew named Trypho how Jesus Christ is the fulfillment of the prophecies of Messiah from the Jewish OT
