 The Father explains that the bridge of His Son reaches from heaven to earth. That Christ, the Son, the bridge, came from heaven to earth. He came from the greatness of divinity, and He took to Himself our humanity without losing anything of the greatness of His divinity. The Father points out to Catherine, nothing of this world would have been sufficient to bridge that distance between God and man that came with sin. But that the Father willed that the Son should take on human nature so that humanity might be restored to the loving union with God that was at the very core of our creation and our being.
