5. We must add a further point of view. The First Letter to the Corinthians (1:18-31) tells us that many of the early Christians belonged to the lower social strata, and precisely for this reason were open to the experience of new hope, as we saw in the example of Bakhita (see section above this one). Yet from the beginning there were also conversions in the aristocratic and cultured circles, since they too were living “without hope and without God in the world”. Myth had lost its credibility; the Roman State religion had become fossilized into simple ceremony which was scrupulously carried out, but by then it was merely “political religion”. Philosophical rationalism had confined the gods within the realm of unreality. The Divine was seen in various ways in cosmic forces, but a God to whom one could pray did not exist. Paul illustrates the essential problem of the religion of that time quite accurately when he contrasts life “according to Christ” with life under the dominion of the “elemental spirits of the universe” (Col 2:8). In this regard a text by Saint Gregory Nazianzen is enlightening. He says that at the very moment when the Magi, guided by the star, adored Christ the new king, astrology came to an end, because the stars were now moving in the orbit determined by Christ[2]. This scene, in fact, overturns the world-view of that time, which in a different way has become fashionable once again today. It is not the elemental spirits of the universe, the laws of matter, which ultimately govern the world and mankind, but a personal God governs the stars, that is, the universe; it is not the laws of matter and of evolution that have the final say, but reason, will, love—a Person. And if we know this Person and he knows us, then truly the inexorable power of material elements no longer has the last word; we are not slaves of the universe and of its laws, we are free. In ancient times, honest enquiring minds were aware of this. Heaven is not empty. Life is not a simple product of laws and the randomness of matter, but within everything and at the same time above everything, there is a personal will, there is a Spirit who in Jesus has revealed himself as Love[3].
