What is all of this about “Mystery”?
Paul writes to Believers he’s never met, encouraging them to the fullness of life in Jesus. In a hymn Paul expressed its vast scope: First, all of physical/spiritual creation is embraced in Jesus as creator and incarnation. Then all of human experience, as he dies and, in God’s Fullness, brings new creation out of death to reconcile the universe to God in Jesus.
This is a surprising, challenging event/narrative. Something pointed to but never fully seen before it became reality in Jesus, his life, teaching, crucifixion, resurrection, and meaning. It is “hidden” for ages as God’s Mystery (M, mysterion), his unique, unexpected way of embracing his creation. God’s kingdom should be glorious, overwhelming, not lowly, hidden, dying. But ironically that obscure, crucified Jesus brings God’s powerful, reconciling love to his whole world, both Jews and all nations, creating a new reality.
