No, Benedict is orthodox…
But he certainly isn’t conservative! At least not by traditional standards. The mere fact that he supports the new mass, ecumenism, and democracy makes him, in the classical sense, a liberal.
Of course, “conservative” is often used as a relative term just meaning wanting to keep the status quo…so someone who would be considered a “liberal” 50 years ago may be a “conservative” today because they got all the changes they wanted…and a “conservative” from 50 years ago would be a “reactionary” today…
But in the classic sense, a liberal is a supporter of the ideals of the french revolution, and a conservative supports the ancien regime…
In this sense, I think I’d call Benedict a moderate…I don’t think he is a monarchist…but at the same time, he is not a radical libertine.
