You have the presumption of being useful to the Kingdom of God assuming as far as possible the saeculum, its life, its words, its slogans, its way of thinking. But reflect, I beg you, what it means to accept this world. Perhaps it means that you have gradually lost yourselves in it? Sadly, it seems you are doing just that. It [is] difficult these days to find you and recognize you in this strange world of yours. Probably we still recognize you because in this process you are taking your time, because you are being assimilated by the world, whether quickly or slowly, but late all the same. We thank you for many things, or rather for almost everything, but we must distinguish ourselves from you in one thing. We have much to admire in you, so we can and must send you this warning.
"Do not conform to this world, but transform yourselves by the renewal of your minds, so that you will be able to recognize the will of God, what is good, what is pleasing to him, what is perfect" (Rom. 12:2). Do not conform! Me syschematizesthe! How well this expression reveals the perennial root of the verb: schema. In a nutshell, all schemas, all exterior models are empty. We have to want more, the apostle makes it our duty, "change your way of thinking, reshape your minds" metamorfoùsthe tè anakainósei toù noós. Paul's Greek is so expressive and concrete! He opposes schèma or morphé – permanent form, to metamorphé – change in the creature. One is not to change according to any model that in any case is always out of fashion, but it is a total newness with all its wealth (anakainósei). [It's] not the vocabulary that changes but the meaning (noùs).
So not contestation, desacralization, secularization, because this is so little compared with Christian anakainósis. Reflect on these words and your naïve admiration for revolution, Maoism, and violence (of which, in any case you are incapable) will abandon you.
Your critical and prophetic enthusiasm has already borne fruit, and we cannot indiscriminately condemn you for this. We simply realize, and tell you sincerely, that we have more esteem for St. Paul's calm and discriminating invitation, "Examine yourselves, to see whether you are holding to your faith. Test yourselves. Do you not realize that Jesus Christ is in you?" (2 Cor. 13:5).
We cannot imitate the world precisely because we have to judge it, not with pride and superiority, but with love, just as the Father loved the world (Jn. 3:16) and for this reason pronounced judgment on it.
Do not phroneîn – think, and in conclusion hyperphroneîn- but sophroneîn, think with wisdom (Cf. Rom. 12:13). Be wise, so that we can discern the signs of the will and the time of God. Not the fashion of the moment, but what is good, honest, and perfect.
We write as unwise to you who are wise, as weak men to you who are strong, as wretched men to you who are even more wretched! And this is stupid of us because there are certainly among you some excellent men and women. But precisely for this reason we need to write foolishly, as the Apostle Paul taught us when he took repeated Christ's words that the Father has hidden wisdom from those who know a lot about these things (Lk. 10:21).
