The enormously prolific Swiss Roman Catholic theologian Hans Urs von Balthasar (1905-1988) was marginalized during much of his life, but his reputation over time has only continued to grow. He was said to be the favorite theologian of John Paul II and is held in high esteem by Benedict XVI. It is not uncommon to hear him referred to as the great Catholic theologian of the twentieth century.
In Balthasar: A (Very) Critical Introduction Karen Kilby argues that although the low regard in which Balthasar was held from the 1950s to 1960s was not justified, neither is the current tendency to lionize him. Instead, she advocates a more balanced approach, particularly in light of a fundamental problem in his writing, namely, his characteristic authorial voice -- an over-reaching -God's eye- point of view that contradicts the content of his theology.
