"This is not the space to analyse these arguments in detail. But I want to remark on a point that Professor George apparently often repeats. Religious leaders, he argues, should stop making all this noise about poverty and injustice. They should focus instead on ‘moral social issues’ such as abortion and same-sex marriage. Why? Because how to achieve social justice is matter of public policy (and messy empirical fact) which cannot be conclusively decided by reason (or ‘Gospel principles’). Reasonable people can disagree on, say, whether the health care system in the US is atrocious or wonderful. But they can know with crystal clear certainty that abortion and same-sex marriage are wrong. So this is what they should really worry about."
