"The rhythms of the knowledge that comes from faith are slow. That is why revelation must also be hidden, veiled. Man's freedom is unable to bear the full weight of God's revelation. Thus the parables spring from the heart of Jesus urgency of the gospel; they are spontaneous, not artificial, they spring from life itself. The parables are, in this perspective, one of the most beautiful fruits of the mystery of the Incarnation, the frontier to which language is pushed by the Son of God, so that it may be adapted to communicate the mystery of the Kingdom in respect to the concrete situation of man."
