Literary criticism, musical criticism and theological criticism are notoriously difficult. The reason that they are so hard is the question of subjectivity. In the early years of the 20th century, a noted conservative theologian said the following of a liberal scholar:
“The Christ that he sees, looking back through nineteen centuries of Catholic darkness, is only the reflection of a Liberal Protestant face, seen at the bottom of a deep well.”
It is a very clever idea but could the equal statement also be said of the more conservative thinker. We want our God to be like our theology says he should be. Otherwise we are wrong and that is hard to bear. We want our heroes to be like us. Otherwise that is burdensome.
