Clear as mud

Here is John Calvin's take on the clear-as-mud school of theology. Yet another example that there's nothing new under the sun.

Do you remember what kind of doctrine candidates for the ministry learned in the schools? You yourself know that it was mere sophistry and sophistry so twisted, involved, tortuous and puzzling that scholastic theology might well be described as a kind of esoteric magic. The denser the darkness in which anyone shrouded a subject and the more he puzzled himself and others with preposterous riddles, the greater his fame for acumen and learning.
