This quote, linked to on Rich Leonardi's blog today, is about Pope Benedict's ideas, but it is true about the political thoughts of anyone who is meaningfully Christian.
Ignatius Insight: What misunderstandings or misrepresentations of Benedict's thinking do you find most bothersome or in need of correction?
Dr. Rowland: Unfortunately many people, in particular journalists, can only think in dialectical categories like: left-wing, right-wing, progressive, conservative. They never ask questions like: conserve what? or progress toward what? It is very difficult to present Ratzinger's ideas in sound-bites without doing violence to the nuances.
There is, for example, a sense in which it may well be right to classify Ratzinger as a progressive in 1964 and a conservative today but what changed is not the actual theological beliefs held by Ratzinger, but the historical and theological contexts. In 1964 to be progressive meant wanting to introduce some flexibility into a theological framework which had become ossified and dry. It meant being critical of Su‡rezian Thomism. Today, being progressive means being in favour of contraceptives, women priests, homosexual "marriage" and Marty Haugen.
As Cardinal Francis George has often written, it is not a case of being left wing or right wing, but being for Christ. In some social contexts that will look right wing, in others, left-wing, but these terms and labels are not the standard, and nor are they stable.
(emphasis mine).
Trying to describe our absolute positions in words like "conservative," "progressive," "left-wing," "right-wing" is, bluntly, useless.
