“Whoever is near me is near the fire.” The Christian must not be lukewarm. The Book of Revelation tells us that this is the greatest danger for a Christian: not that he may say no, but that he may say a very lukewarm yes. This being lukewarm is what discredits Christianity. Faith must become in us flame of love, flame that really fires up my being, becomes the great passion of my being, and so it fires also my neighbor. This is the way of evangelization: “Accéndat ardor proximos,” that truth may become in me charity and charity may lit up also the other. Only in this lighting up the other through the flame of our charity, evangelization really grows, the presence of the Gospel, which is no longer just word, but a lived reality.
St. Luke tells us that at Pentecost, in this foundation of the Church of God, the Holy Spirit was the fire that has transformed the world, but fire in the form of tongues, that is, fire which is however reasonable, that is spirit, which is also understanding , fire that is joined to the thought, to the “mens.” And this intelligent fire, this “sobria ebrietas,” is characteristic of Christianity. We know that fire is at the beginning of human culture, fire is light, heat, power to transform. Human culture begins when man has the power to create fire: with fire it can destroy, but with fire it can transform and renew. The fire of God is transforming fire, the fire of passion – certainly – that destroys also so much in us, that leads to God, but fire especially that transforms, renews and creates a novelty in man, which becomes light in God.
