Therefore, my venerable Predecessor, Pope John Paul II, described St Justin as a “pioneer of positive engagement with philosophical thinking - albeit with cautious discernment… Although he continued to hold Greek philosophy in high esteem after his conversion, Justin claimed with power and clarity that he had found in Christianity ‘the only sure and profitable philosophy’ (Dial. 8: 1)” (Fides et Ratio, n. 38).
Overall, the figure and work of Justin mark the ancient Church’s forceful option for philosophy, for reason, rather than for the religion of the pagans. With the pagan religion, in fact, the early Christians strenuously rejected every compromise. They held it to be idolatry, at the cost of being accused for this reason of “impiety” and “atheism”.
Justin in particular, especially in his first Apology, mercilessly criticized the pagan religion and its myths, which he considered to be diabolically misleading on the path of truth.
Philosophy, on the other hand, represented the privileged area of the encounter between paganism, Judaism and Christianity, precisely at the level of the criticism of pagan religion and its false myths. “Our philosophy…”: this is how another apologist, Bishop Melito of Sardis, a contemporary of Justin, came to define the new religion in a more explicit way (Ap. Hist. Eccl. 4, 26, 7).
In fact, the pagan religion did not follow the ways of the Logos, but clung to myth, even if Greek philosophy recognized that mythology was devoid of consistency with the truth.
Therefore, the decline of the pagan religion was inevitable: it was a logical consequence of the detachment of religion - reduced to an artificial collection of ceremonies, conventions and customs - from the truth of being.
Justin, and with him other apologists, adopted the clear stance taken by the Christian faith for the God of the philosophers against the false gods of the pagan religion.
It was the choice of the truth of being against the myth of custom. Several decades after Justin, Tertullian defined the same option of Christians with a lapidary sentence that still applies: “Dominus noster Christus veritatem se, non consuetudinem, cognominavit - Christ has said that he is truth not fashion” (De Virgin. Vel. 1, 1).
It should be noted in this regard that the term consuetudo, used here by Tertullian in reference to the pagan religion, can be translated into modern languages with the expressions: “cultural fashion”, “current fads”.
In a time like ours, marked by relativism in the discussion on values and on religion - as well as in interreligious dialogue - this is a lesson that should not be forgotten.
To this end, I suggest to you once again - and thus I conclude - the last words of the mysterious old man whom Justin the Philosopher met on the seashore: “Pray that, above all things, the gates of light may be opened to you; for these things cannot be perceived or understood by all, but only by the man to whom God and his Christ have imparted wisdom” (Dial. 7: 3).
