Bonny’s essay is long, and I only looked at passages explicitly mentioning natural law. He quotes the work instrument for a Synod:* “In a vast majority of responses and observations, the concept of natural law today turns out to be, in different cultural contexts, highly problematic, if not completely incomprehensible. The expression is understood in a variety of ways, or simply not understood at all”*.
I would understand natural law as in Romans 2:14-15 - that we are all moral agents and we all wrestle over the right thing to do.
But some Catholics mean natural law to refer instead to a system of ethics produced by Thomas Aquinas, and a few see that as providing strict universal rules on what is good or bad - for them wrestling over the right thing to do would be moral relativism, follow the rule-book, never question the rule-book.
It seems it’s not just Bonny who finds the rule-book a poor substitute for a moral conscience. He quotes an International Theological Commission document:
“Natural law [cannot], therefore, be presented as an already established set of rules that impose themselves a priori on the moral subject; rather, it is a source of objective inspiration for the deeply personal process of making a decision”.
According to polls, most Catholics ignore rule-books anyway, at least when it comes to marriage and family,
they are a law for themselves, even though they do not have the law. They show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts sometimes accusing them and at other times even defending them.
Which is either very heartening or appalling anarchy, depending on what you think about rule-books.
