I am aware of the ways in which charity has been and continues to be misconstrued and emptied of meaning, with the consequent risk of being misinterpreted, detached from ethical living and, in any event, undervalued. In the social, juridical, cultural, political and economic fields — the contexts, in other words, that are most exposed to this danger — it is easily dismissed as irrelevant for interpreting and giving direction to moral responsibility. Hence the need to link charity with truth not only in the sequence, pointed out by Saint Paul, of veritas in caritate (Eph 4:15), but also in the inverse and complementary sequence of caritas in veritate. Truth needs to be sought, found and expressed within the “economy” of charity, but charity in its turn needs to be understood, confirmed and practised in the light of truth. In this way, not only do we do a service to charity enlightened by truth, but we also help give credibility to truth, demonstrating its persuasive and authenticating power in the practical setting of social living. This is a matter of no small account today, in a social and cultural context which relativizes truth, often paying little heed to it and showing increasing reluctance to acknowledge its existence.

Through this close link with truth, charity can be recognized as an authentic expression of humanity and as an element of fundamental importance in human relations, including those of a public nature. Only in truth does charity shine forth, only in truth can charity be authentically lived. Truth is the light that gives meaning and value to charity. That light is both the light of reason and the light of faith, through which the intellect attains to the natural and supernatural truth of charity: it grasps its meaning as gift, acceptance, and communion. Without truth, charity degenerates into sentimentality. Love becomes an empty shell, to be filled in an arbitrary way. In a culture without truth, this is the fatal risk facing love. It falls prey to contingent subjective emotions and opinions, the word “love” is abused and distorted, to the point where it comes to mean the opposite. Truth frees charity from the constraints of an emotionalism that deprives it of relational and social content, and of a fideism that deprives it of human and universal breathing-space. In the truth, charity reflects the personal yet public dimension of faith in the God of the Bible, who is both Agápe and Lógos: Charity and Truth, Love and Word. – from Caritas in Veritate (2009)
