Saint Paul, in his hymn to charity, 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". 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.
This proper way of serving others also leads to humility. The one who serves does not consider himself superior to the one served, however miserable his situation at the moment may be. Christ took the lowest place in the world - the Cross - and by this radical humility he redeemed us and constantly comes to our aid. Those who are in a position to help others will realize that in doing so they themselves receive help; being able to help others is no merit or achievement of their own. This duty is a grace. The more we do for others, the more we understand and can appropriate the words of Christ: "We are useless servants". We recognize that we are not acting on the basis of any superiority or greater personal efficiency, but because the Lord has graciously enabled us to do so. There are times when the burden of need and our own limitations might tempt us to become discouraged. But precisely when we are helped by the knowledge that, in the end, we are only instruments in the Lord's hands; and this knowledge frees us from the presumption of thinking that we alone are personally responsible for building a better world. In all humility we will do what we can, and in all humility we will entrust the rest to the Lord.(Deus Caritas Est)
