We've been having an interesting back-and-forth since Pope Benedict remarked that he approved of local bishops denying communion to public officials and lawmakers around the world who supported legalized abortion.
Don't worry - we both definitely agree that this is just the latest awful thing that the Sith Pope has done. Karl thinks this is an irresponsible interference in state affairs by the church (since the Church is attempting to wield its religious influence on legislators in order to change laws), which from his constitutional perspective is a violation of the maxim of Separation of Church and State.
The idea of excommunication is also theologically suspect - ideally, Christians should like to think that the Instituted Sacraments (communion and baptism) belong not to the Church (the human institution), but instead to God. Otherwise why are we coming to church to receive them? [These are called the Instituted Sacraments because they are the only ones performed by Jesus himself, and so they're considered the only ones necessary "for salvation" - whatever that means.] If this is true, certainly it falls outside of human authority to denying any other human that which is God's to begin with. And even more so, it's probably downright sinful to use possessions of God as political leverage!
But Karl goes a bit further:
There is also a difference between actions of a church affecting the entirety of a nation and those actions affecting isolated individuals. If there is a problem with a church harboring undocumented persons, it is substantially different problem than if the church were demanding its standards be imposed on the lives of all persons in the nation (e.g. excluding immigrants).I find it a confusing work of legalistic parsing to say that an individual should advocate their religion-based political views without "[compelling] others to act in accord with the religion's teachings]". That's not very good advocacy, now is it? If we're going to allow self-avowed religious people into government, then we're also allowing the judgments and opinions they carry, many of which may be based on their religious beliefs alone, to inform the ways they make and interpret our law and policy.
Might a religion express a view on the rightness or wrongness of an activity? Of course it may, and should, do so. And based on that, might an individual person of faith advocate such a position? Absolutely. But the religion should not compel its members to compel others to act in accord with the religion's teachings, particularly where that violates the member's duties to the state. (I'm vaguely reminded of rendering things to Caesar and to God here...)
Karl's problem seems to be with religious leaders who essentially command that adherents behave a certain way, especially when those "adherents" are public officials and that "certain way" contradicts Constitutional principles and duties. But from there he says that the Church should "withdraw from the secular affairs of the state."
I think Karl is giving far too much credit to the Pope and people like him by saying his remarks (and that's all they were) would "force Catholic legislators to choose between a duty to uphold the Constitution and their very faith." I find that most religious people I talk to understand, amongst themselves, something that many secularists refuse to understand in their propensity for overgeneralization of the religious: faith is so important to individuals precisely because it is so individual. The Bible, the Pope, the bishop, the pastor, the imam, the rabbi, the monk, the nun - sure, these are authorities in religious life, but an individual's faith is a lot more than just what a pastor tells him. A great deal of internal confirmation and struggle and questioning goes into everyone's faith formation - it is important to remember this when we feel to urge to blame "sheep-like Christians" for all the nation's problems.
Catholic legislators have been, are, and will be doing something that religious people through millennia have done: figure out how to live in between what they feel to be right and what they are being told is right. For some, this isn't a conflict at all, and I think it's safe to assume that those people, if they're legislators, were elected to represent exactly those views. For others, they'll be doing the most human part of religion, the part that makes it worth it, the part that brings change and renewal. In fact, it is this process of challenging religious authority that has brought about much of the social change that secular liberals claim as their own morals today.
When Karl supports the Church's complete retreat from public life over what the Pope says, he's giving credence to a frightfully small view of what it's actually like to allow religious values to play out in one's life. It's as if he's validating the idea that Catholics will basically do whatever the Pope says. Or that Evangelicals do whatever the Bible "says". That view, of course, makes for a much bigger target for enlightened academics like ourselves, but it's complete fiction.
Social progress begins with agonized individuals. Always. This is the reality of what it means to be human. Christianity is successful because it gives a way to understand this reality and then continue living and working for justice anyway. Because after torture and death, there is resurrection and life.
Religious leaders have done great harm and great help - but both have only been enabled by the extent to which religious people have reflected upon whether what their authorities say agree with what they themselves feel is right, and good, and a joyful thing.
We should invite this smoldering soul-searching among our religious and our civic leaders, rather than demanding a sterile system where input equals output and nothing ever surprises us. When an individual, upon further meditation, finds that her idea of justice is not what the existing religious and civic authorities are thinking of, that person can be called a citizen and a Christian.
