You see that the love [the Apostle] John speaks of is not the love of soap operas! No, it is something else. Christian love has a particular quality: concreteness. Christian love is concrete. Jesus Himself, when He speaks of love, speaks to us about concrete things: feeding the hungry, visiting the sick, and many concrete things. Love is concrete… .
And when this concreteness is not there, you can live a Christianity of illusions, because you don’t understand where the centre of Jesus’ message is. This love does not arrive at concrete being: it is a love of illusions, like the illusions the disciples had when, looking at Jesus, they thought He was a ghost.”
