“God’s mission” is not a trope for doing what we really want to do, or feel we ought to do; it is not the pursuit of the already determined concept of the good or the just. God’s mission is not theological cover for our ambitions to “save” the world. God’s mission is about God. And if anything is about God, it is not about us, unless God makes it so.
The article helpfully distinguishes a biblical view of the missio dei derived Christologically in reference to the eucharist.
