St Paul gave a motto to the Christians at Ephesus: Instaurare omnia in Christo: to fill everything with the spirit of Jesus, placing Christ at the centre of everything. “And I, when I am lifted up from the earth, will draw all things to myself." Through his incarnation, through his work at Nazareth and his preaching and miracles in the land of Judea and Galilee, through his death on the cross, and through his resurrection, Christ is the centre of the universe, the firstborn and Lord of all creation.
Our task as Christians is to proclaim this kingship of Christ, announcing it through what we say and do. Our Lord wants men and women of his own in all walks of life. Some he calls away from society, asking them to give up involvement in the world, so that they remind the rest of us by their example that God exists. To others he entrusts the priestly ministry. But he wants the vast majority to stay right where they are, in all earthly occupations in which they work: the factory, the laboratory, the farm, the trades, the streets of the big cities and the trails of the mountains. (Christ is passing by, 105)
