~Deus Caritas Est~
“God is love, and he who abides in love abides in God, and God abides in him” (1 Jn 4:16). These words from the First Letter of John express with remarkable clarity the heart of the Christian faith: the Christian image of God and the resulting image of mankind and its destiny. In the same verse, Saint John also offers a kind of summary of the Christian life: “We have come to know and to believe in the love God has for us”.
We have come to believe in God's love: in these words the Christian can express the fundamental decision of his life. Being Christian is not the result of an ethical choice or a lofty idea, but the encounter with an event, a person, which gives life a new horizon and a decisive direction. Saint John's Gospel describes that event in these words: “God so loved the world that he gave his only Son, that whoever believes in him should ... have eternal life” (3:16)
~Deus Caritas Est~
17. "True, no one has ever seen God as he is. And yet God is not totally invisible to us; he does not remain completely inaccessible. God loved us first, says the Letter of John quoted above (cf. 4:10), and this love of God has appeared in our midst. He has become visible in as much as he “has sent his only Son into the world, so that we might live through him” (1 Jn 4:9). God has made himself visible: in Jesus we are able to see the Father (cf. Jn 14:9). Indeed, God is visible in a number of ways. In the love-story recounted by the Bible, he comes towards us, he seeks to win our hearts, all the way to the Last Supper, to the piercing of his heart on the Cross, to his appearances after the Resurrection and to the great deeds by which, through the activity of the Apostles, he guided the nascent Church along its path. Nor has the Lord been absent from subsequent Church history: he encounters us ever anew, in the men and women who reflect his presence, in his word, in the sacraments, and especially in the Eucharist. In the Church's Liturgy, in her prayer, in the living community of believers, we experience the love of God, we perceive his presence and we thus learn to recognize that presence in our daily lives. He has loved us first and he continues to do so; we too, then, can respond with love. God does not demand of us a feeling which we ourselves are incapable of producing. He loves us, he makes us see and experience his love, and since he has “loved us first”, love can also blossom as a response within us."
