Here is an interview Peter Leithart did with the Society for the Advancement of Eccelsial Theology. I have not heard of this particular group before. However, the interview is very helpful. Dr. Leithart makes the simple point that the entire Christian life is political because we serve a King and live in a Kingdom that is not of this world. I especially enjoyed the phrase "Christians never have limited political capital." I have reprinted the interview in full below. It can be difficult in places, but I think you can get the main point.
1. For those who are not familiar with
your work, can you describe your contribution to the question of how the
individual Christian and the Church relates to the State?
PL: I have addressed church-state
questions in many of my books, though obliquely rather than directly. I
have explored those themes in various books – The Kingdom and the Power,
Against Christianity, and more recently my historical study, Defending
Constantine, where I address church-state relations more directly.
But I am convinced that political concerns are
inherent in theology. Political theology is not some specialized branch
of theology, but a dimension of all theology. Politics is not simply
about passing this legislation or electing that candidate. Politics
addresses questions about the distribution of power, and more broadly questions
about the shape and future of a group. Theology cannot help but address
those questions, and do it all the time. The Bible certainly deals with
political questions like this.
So, even when I am not doing political
theology, I am doing political theology. Let me given a couple of
examples of what I mean. Ecclesiology has been a major focus of my work,
and, as I see it, that bumps directly up against political questions. The
intimate connection between ecclesiology and politics has been obscured in
modernity because the church has been marginalized and has allowed itself to be
transformed into a sociologically invisible and politically innocuous religious
group. Scripture, by contrast, treats the church as a political entity in
itself, each individual congregation as an outpost of the heavenly empire of a
heavenly Emperor. That means that the church and its claims about
Jesus, sin, and salvation are political claims, necessarily. I’ve also
written a lot on sacramental theology, and I have had the same concerns in
view. Sacraments ritualize and represent the kind of community that the
church is and aspires to be, and that again means that the sacraments
inevitably have a political dimension. I think in fact that the eclipse
of sacramental consciousness and sacramental theology is one of the great
political tragedies of the past several centuries of church history. The
Eucharist has been privatized and individualized, and that means it lacks the
political edge – as the table of the kurios, the Lord – that it has in
the New Testament. How many wars among Christian nations would have been
avoided if our sense of community had been shaped by being table fellows with
one another?
2. Richard Mouw and Carl F. H.
Henry have suggested that the Church’s role is not coterminous with the
responsibility possessed by individual believers. Do you agree or
disagree?
PL: Yes, I think that is fairly
obvious. An individual believer might be a judge who sentences someone to
prison or to death; the church as an institution can never do that. As always,
though, the devil is in the details. I don’t take that distinction to
imply that the church as an institution has only an “indirect” political role,
that it can never intervene in political affairs as the church. Over the
centuries, the church as an institution, or representatives of the church, have
addressed political issues directly, without overstepping the bounds of
churchly authority. Ambrose rebukes Theodosius and denies him communion
because of a rash and bloody military episode. During the middle ages, the
church disciplined nobles who defied the truce and peace of God. I think it’s
entirely proper for the church to speak as church to political injustices.
