A friendlier way to characterize them would be that they approach the faith like they approach their politics. To them, it seems like the faith is just a political animal which they can alter and amend to fit their ideological biases. But the faith is not an ideology (thank God for that). Nor is it a democracy. Nor is truth dependent upon the whims of the mob.
Oddly enough, I’ve noticed a pretty strong connection between “conservative” Catholics and politics, at least in the US; in French Canada where I live the political connection isn’t so strong, all our political parties are much farther left than in the US and the hot-button items like same-sex marriage and abortion have, for better or for worse (actually for worse…) been decided. It used to be much different before Vatican II when our (somewhat Jansenist) local Church was in bed with the very conservative and repressive government of the day (the overthrow of that government coincided, almost exactly in time, to Vatican II).
But at the core, the problem is their notion of what progress even means. Their form of progress is arbitrary and destructive. It’s arbitrary because it is not really guided by principle. It is destructive because it can and does utterly destroy what came before.
I don’t think it’s fair to categorize all of the “progress” intended by “progressives” as destructive. It was after all “progressive” politics that eliminated slavery, racial discrimination, gave women the vote, and provided at least a very basic social safety net. It’s more complicated, a mixed bag, often a case of “three steps forward, two steps backwards” and sometimes, as we are currently seeing, two steps forward and three steps backwards. But I am not so ready to dismiss all “progressives” in spite of some really weird things that some of them promote like same-sex marriage.
I don’t think you can ever reconcile those two conceptions of progress. The very act of demanding something like acceptance of gay marriage is in itself a rejection of the promises of Christ and the Holy Spirit. I don’t think they are explicitly guilty of consciously doing this, however, because I have not seen much evidence that they realize it.
While I think that same-sex marriage is an oxymoron, and I equally think that it should be opposed, it’s not clear to me yet that it is the slippery slope we make it out to be; after all it is a issue that only targets a small percentage of the population, and I think there are greater threats to marriage, namely no-fault civil divorce, not to mention the corrosive effects of such things as pornography or the pill, on marital intimacy which can in turn cause great marital stress. Lack of chastity in general, not homosexual behaviour, IMHO is the real threat to the institution of marriage; in fact homosexual behaviour for the most part is probably less of a threat as few homosexuals engage in heterosexual marriage, though of course some do that haven’t come to terms with their same-sex attraction. At least some of the people within the Church that I know are “progressives” on this issue are not calling for the Church to suddenly determine that same-sex marriage actually exists and is sacramental, rather they are saying that civil marriage is outside the scope of the Church’s authority and that since it is aimed at a small minority, the real threat to marriage is small and we should live and let live. Of course, often forgotten in that discussion, is the issue of children (either adopted, from surrogate parenthood or a previous heterosexual marriage), and that’s a shame as their rights need to at least be discussed and that’s where a big part of my own objection to SSM lies.
But I digress, my point really is that “progressive” versus “conservative” is not such a clear-cut issue (except perhaps in highly polarized US politics!), and that not all progress by “progressives” has been bad or on evil foundations. Many Catholics that I know are very socially “progressive” on economics and help for the poor while being very conservative on issues like abortion, and same-sex marriage, while some others are more of a mixed bag, progressive on some issues (female ordination for instance) while very conservative on life issues (such as abortion); others are conservative liturgically but progressive socially. Which I think, points to the necessity to stopping the useless and divisive categorization into Catholics into “good” (conservative) and “bad” (progressive) camps, or vice-versa depending on your perspective. Life is complex and messy, and such black-and-white thinking is in fact fundamentally incompatible with a Church that labels itself “catholic” and as such is a hospital for
all sinners, which of course we all are regardless of where we are on the spectrum. Moreover that spectrum is fluid, some individuals moving back and forth and changing their views with time. Chasing away those who don’t agree with us is never a winning strategy for evangelization.
