He descended first to the underworld...   
The caption cites Ephesians 4 and Colossians 2  but to understand Christ's descent into the underworld in the time between the Crucifixion and the Resurrection and His eternal victory over the power of death, theologians have looked to many passages, among them:1 Peter 3:19-20    1 Peter 4:6    Acts 2: 31   2 Corinthians 2:14
The descent of the Baptized into Christ's own death, their deliverance, and final Resurrection is prefigured.

All are Welcome in this Place...Christian Hymn Sung by RICHARD CARNEY Let us build a house where love can dwell And all can safely live, A place where saints and children tell How hearts learn to forgive. Built of hopes and dreams and visions, Rock of faith and vault of grace; Here the love of Christ shall end divisions; Let us build a house where prophets speak, And words are strong and true, Where all God's children dare to seek To dream God's reign anew. Here the cross shall stand as witness And a symbol of God's grace; Here as one we claim the faith of Jesus: Let us build a house where love is found In water, wine and wheat: A banquet hall on holy ground, Where peace and justice meet. Here the love of God, through Jesus, Is revealed in time and space; As we share in Christ the feast that frees us: All are welcome, all are welcome, All are welcome in this place.
