Christian tradition has always been rich in signs and symbols: I think for example of the Cross, icons, images of the Virgin Mary, Christmas cribs, stained-glass windows and pictures in our churches. A significant part of mankind's artistic heritage has been created by artists and musicians who sought to express the truths of the faith.

In social networks, believers show their authenticity by sharing the profound source of their hope and joy: faith in the merciful and loving God revealed in Christ Jesus. This sharing consists not only in the explicit expression of their faith, but also in their witness, in the way in which they communicate "choices, preferences and judgements that are fully consistent with the Gospel, even when it is not spoken of specifically" (Message for the 2011 World Communications Day). A particularly significant way of offering such witness will be through a willingness to give oneself to others by patiently and respectfully engaging their questions and their doubts as they advance in their search for the truth and the meaning of human existence. The growing dialogue in social networks about faith and belief confirms the importance and relevance of religion in public debate and in the life of society.

For those who have accepted the gift of faith with an open heart, the most radical response to mankind's questions about love, truth and the meaning of life - questions certainly not absent from social networks - are found in the person of Jesus Christ. It is natural for those who have faith to desire to share it, respectfully and tactfully, with those they meet in the digital forum. Ultimately, however, if our efforts to share the Gospel bring forth good fruit, it is always because of the power of the word of God itself to touch hearts, prior to any of our own efforts. Trust in the power of God's work must always be greater than any confidence we place in human means.

In the digital environment, too, where it is easy for heated and divisive voices to be raised and where sensationalism can at times prevail, we are called to attentive discernment. Let us recall in this regard that Elijah recognized the voice of God not in the great and strong wind, not in the earthquake or the fire, but in "a still, small voice" (1 Kg 19:11-12). We need to trust in the fact that the basic human desire to love and to be loved, and to find meaning and truth - a desire which God himself has placed in the heart of every man and woman - keeps our contemporaries ever open to what Blessed Cardinal Newman called the "kindly light" of faith.

Social networks, as well as being a means of evangelization, can also be a factor in human development. As an example, in some geographical and cultural contexts where Christians feel isolated, social networks can reinforce their sense of real unity with the worldwide community of believers. The networks facilitate the sharing of spiritual and liturgical resources, helping people to pray with a greater sense of closeness to those who share the same faith.

An authentic and interactive engagement with the questions and the doubts of those who are distant from the faith should make us feel the need to nourish, by prayer and reflection, our faith in the presence of God as well as our practical charity: "If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal" (1 Cor 13:1).

In the digital world there are social networks which offer our contemporaries opportunities for prayer, meditation and sharing the word of God. But these networks can also open the door to other dimensions of faith. Many people are actually discovering, precisely thanks to a contact initially made online, the importance of direct encounters, experiences of community and even pilgrimage, elements which are always important in the journey of faith.

In our effort to make the Gospel present in the digital world, we can invite people to come together for prayer or liturgical celebrations in specific places such as churches and chapels. There should be no lack of coherence or unity in the expression of our faith and witness to the Gospel in whatever reality we are called to live, whether physical or digital. When we are present to others, in any way at all, we are called to make known the love of God to the furthest ends of the earth.

I pray that God's Spirit will accompany you and enlighten you always, and I cordially impart my blessing to all of you, that you may be true heralds and witnesses of the Gospel. "Go into all the world and preach the Gospel to the whole creation" (Mk 16:15).
