A figural representation of Jesus and the woman caught in adultery found in the New Testament. The woman, condemned to death by stoning for committing the act of adultery (sexual relations outside of marriage) is brought before Jesus. His response to her crime? He kneels down to write on the ground, stands up and says "Whoever among you without sin can throw the first stone."
In the same way that Jesus humbled himself on the cross when he took on the sin of the world, Jesus physically humbles himself before the woman caught in adultery in the gesture of a marriage proposal. This response signifies Christ's desire to be united with humanity even in the midst of our darkest moments.
