The Church is called the Body of Christ. The head and the body do not separate. It is worth noting that Christ did not abandon his Church even when it betrayed him. Nor should we, even if it betrays us.
When Jesus appeared to the disciples after the Resurrection, he still had the wounds. He is no longer dying on the cross, but the wounds remain with him - it looks like forever, though "forever" is a word that may turn out to not have a clear meaning. I suppose it works in reverse now as well, that we are to perceive the resurrection even on Good Friday.
