It is significant that this particular passage from John’s Gospel is used for the scrutinies. John uses the term semeion to indicate that the miracle points beyond itself to Jesus’ divinity, as often prefigured in the Old Testament. The act of washing in the Pool of Siloam  prefigures  Baptism, where the blind man is "illuminated" or "enlightened" to receive the light of faith. It is also significant that Jesus uses clay and spittle to heal the blind man echoing the act of creation in Genesis where God formed man from the dust and gave him both biological and supernatural life.  Similarly, in the waters of Baptism, one becomes His child forever and can now share in His divine life through the other six sacraments of the Church. The narrative contrasts the gradual spiritual sight gained by the blind man with the willful, stubborn blindness of the Pharisees, who, despite seeing the miracle, refused to believe, leaving them in their sin. By healing on the Sabbath, Jesus shows that the day is meant for restoring life and doing good, inaugurating the new creation. These acts signify that the Father’s work of redemption continues, fulfilling the true purpose of the Sabbath—spiritual and physical liberation. Let us then show others how to live in this new light always.
