People in Christ's time did understand what Jesus did----but it took them time to comprehend it.  We're had more than 2000+ years to reflect upon it.  Sure we understand it better.

Again, neither I nor Cardinal Kasper are denying the miracle of Jesus walking on the water.  But which miracle of Jesus is MORE IMPORTANT in demonstrating to the people the hope and promise of a future Resurrection---walking on the water or raising Lazarus from the Dead? Even our liturgies demonstrate that reality.   The Gospel of the raising of Lazarus is used in Funeral Liturgies---not the story of Jesus walking on the water.

Again, you are not able to clearly understand what Kasper is writing.  Stop condemning theological perspectives that your ignorance can't grasp.
