These trends went on the cardinal boost the spreading of a "culture of death". Then, card. Dias spoke of "deliberate abortion (or the massacre of innocent unborn children)", of "divorce, which kills the sacred bond of marriage blessed by God)", of "social, economic and political injustice". And he added: "the two institutions of human society" which are especially vulnerable" to this culture are "the family and the young". In such scenario went on the cardinal , the Christians cannot sit on the fence and be passive onlookers". "Faithful to our call to be the salt of the earth and the light of the world, we must be proactive in reading the signs of the time". The Christians’ testimony is "what the world needs today", emphasised Dias, who added that "our peers believe the witnesses more than the teachers".
