When the debate begins, the first question Trypho asks is about circumcision, which was a major stumbling block for Christian converts in the early days of the Church, when many converts were confused on whether they first needed to convert to Judaism before becoming Christian. Converting to Judaism meant you had to be circumcised. St Paul in his Epistles famously reassures his Gentile converts that they only needed to be circumcised in their heart. Not only did Christian converts not need to be circumcised; it was wrong to require that converts be circumcised, and he is quite strident in his exhortations in Galatians in particular. […]

How do the Jewish Scriptures and Greek philosophy relate to the Good News, the Gospel of Jesus Christ? Do they conflict with the Gospel? Can Christians profitably study Jewish Scripture and Greek philosophy? These are the questions this dialogue explores, and St Justin the Martyr was one of the first of apostolic fathers to explore these issues. When you read teachings you have read many times before, remind yourself, you are probably reading the original source. […]
Justin opens his apology, “Reason directs those who are truly pious and philosophical to honor and love only what is true, declining to follow the opinions of the ancients if these be worthless,” a surprising argument, given the weight that the Romans placed on the ancient traditions. Right belief matters, “the lover of truth should choose to do and say what is right, by all means, and if threatened with death,” be willing to lay down his own life.

Justin also echoes Plato when he says “rulers should rule in obedience, not to violence and tyranny, but to piety and philosophy,” a somewhat ironic wish since under the rule of the philosopher emperor Marcus Aurelius he would suffer a martyr’s death.
