Sidebar: I won’t get into the thick dogmatic background to all this, but if you want to get into it for yourself, the best book is John Flett’s The Witness of God. There are a number of posts here at DET on this book. Here is one; follow the “mission” tag for more.
Anyway, what I think is especially interesting on this from Migliore is how he brings the munus triplex (cf. Part 1) to bear with reference to mission and how the church ought to shoulder its missionary task. So, with altogether enough ado…
Daniel L. Migliore, Faith Seeking Understanding, 266-7.
The missionary activity of the church should be understood as participation in the mission of Jesus Christ … The doctrine of the threefold office of Christ also brings clarity and direction to the understanding of the church and its mission. Of course, to speak of the church’s mission in terms of the threefold office of Christ cannot possible mean that the church replaces Christ as the primary missionary, or that the church perfects an essentially defective mission of Christ. On the contrary, the living Christ continues his missionary work in the world, and the church is called to participate in his work and to be guided by it. Hence the church’s mission will always include the priestly activity of proclaiming forgiveness and reconciliation in the name of Christ; it will always include the prophetic activity of teaching God’s will made known in Christ and denouncing injustice and oppression as opposing God’s will; and it will always include the royal activity of being a protector and advocate of the weak and lowly and using what resources and influence it has not for its own sake but for the sake of God’s coming reign of justice and peace that has downed in power in the royal life, death, and resurrection of Christ. If it is Christ-centered, the missionary activity of the church will follow the way of the cross and will show a partiality to outsiders, strangers, and all those considered alien, unworthy, or disturbingly different.
