Justin Martyr on truth outside the Church

Justin walked into the Roman intellectual world and argued that Christianity could answer it on its own terms. He had studied philosophy before conversion, then wrote to emperors and educated pagans explaining why worshipping Christ was not superstition, atheism, or sedition. That move matters: Christian apologetics became more than denunciation, because Justin showed how to engage Plato, Stoicism, Roman law, Jewish scripture, and martyrdom in the same argument. He died for the faith he tried to make intelligible.
