The universality and integrality of the salvation wrought by Christ makes indissoluble the link between the relationship that the person is called to have with God and the responsibility he has towards his neighbour in the concrete circumstances of history. This is sensed, though not always without some confusion or misunderstanding, in humanity's universal quest for truth and meaning, and it becomes the cornerstone of God's covenant with Israel, as attested by the tablets of the Law and the preaching of the Prophets. This link finds a clear and precise expression in the teaching of Jesus Christ and is definitively confirmed by the supreme witness of the giving of his life, in obedience to the Father's will and out of love for his brothers and sisters. To the scribe who asks him “Which commandment is the first of all?” (Mk 12:28), Jesus answers: “The first is: ‘Hear, O Israel: the Lord our God, the Lord is one; and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength'. The second is this: ‘You shall love your neighbour as yourself'. There is no other commandment greater than these” (Mk 12:29-31). Inextricably linked in the human heart are the relationship with God — recognized as Creator and Father, the source and fulfilment of life and of salvation — and openness in concrete love towards man, who must be treated as another self, even if he is an enemy (cf. Mt 5:43-44). In man's inner dimension are rooted, in the final analysis, the commitment to justice and solidarity, to the building up of a social, economic and political life that corresponds to God's plan.
