Media outlets have been abuzz that Pope Benedict has revised the Catholic Church’s teaching on contraception by allowing it certain, extreme cases.
A closer look at the interview reveals he has done no such thing:
The first part of his answer makes clear that he still sees the act as objectively disordered. His point is that while two acts might both be intrinsically evil, they are not equally so. If an agent decided to commit the lesser evil, then this would be a step in the right direction; nevertheless, it is still immoral.
Janet Smith’s bank heist analogy illustrates this point well:
Leo Strauss criticized Thomas Aquinas (and by logical extension, the Catholic Church) for supporting fixed moral principles. He believed such norms were too rigid and impractical for the messy, complicated world of human affairs. Pope Benedict's nuanced comments on contraception show an awareness of the need for principles which are BOTH fixed and flexible.
