Deus Caritas Est §34

³⁴ Interior openness to the Catholic dimension of the Church cannot fail to dispose charity workers to work in harmony with other organizations in serving various forms of need, but in a way that respects what is distinctive about the service which Christ requested of his disciples. Saint Paul, in his hymn to charity (cf. 1 Cor 13), teaches us that it is always more than activity alone: “If I give away all I have, and if I deliver my body to be burned, but do not have love, I gain nothing” (v. 3). This hymn must be the Magna Carta of all ecclesial service; it sums up all the reflections on love which I have offered throughout this Encyclical Letter. Practical activity will always be insufficient, unless it visibly expresses a love for man, a love nourished by an encounter with Christ. My deep personal sharing in the needs and sufferings of others becomes a sharing of my very self with them: if my gift is not to prove a source of humiliation, I must give to others not only something that is my own, but my very self; I must be personally present in my gift.
