On a scale of 1 to 10 ...

That must have been a great trip you made in Spain.  If I were in that cathedral I sure wouldn't have been in the middle in the path of the swinging pendulum held on by some clerics.

For my interest in art I'm glad the Catholic Church decided to take a loose interpretation of the commandment about graven images.  If they had taken the same approach as Islam or The Orthodox Church (Iconoclasm seriously limited the flowering of Byzantine art in my opinion), it would have greatly impoverished western art and its assimilation of Greek art.  The early Protestants wanted to simplify the ornate trappings (sometimes with good reason), but I'm glad they for the most part welcomed and nurtured sacred art music.

About "rejection of modern medical science and technology" I think you might be conflating the Catholics with some "born again" evangelical protestant groups (the latter being much more likely to take that anti-intellectual position).
