"...in the words of Karl Barth...,"Jesus is man as God willed and created him....The nature of the man Jesus is the key to the problem of the human. This man is man." Historical Christologies sometimes ask, "Was Jesus truly human?" Barth and [Epistle to the] Hebrews reverse the question: given that Jesus was the paradigm of true humanness, are we, the readers, truly human?
