... attempts to rationalise theocracy): here.
Okay, before I'm jumped on I realise that that's a slightly cheap shot to take at Catholic theologian Austen Ivereigh. To be fairer to him, much of what is contained in the piece that I linked to above is populism rather than outright theocratic reasoning, though I'm not a fan of the former a and I'm willing to bet that we'll see more of the latter in the book it is based on (assuming someone sends me a review copy), especially given the publisher - Our Sunday Visitor Press/Publishing - which is basically a Catholic propaganda organ. (That said, even propaganda type presses can sometimes produce decent books ... we'll see if this turns out to be an example or not.)
In any event, the arguments are weak. Importantly, the cultural meaning of marriage has already changed. That horse has bolted. For a start, marriage has no strong connection with children these days: many married couples have no intention of having children, and many couples do have children without getting formally married. The nature of marriage is more complex, and there is nothing about marriage, as it actually operates in the twenty-first century, that could not be extended easily to same-sex couples who want it. Even in past centuries, the cultural significance of marriage was not stable.
I see that there are three other pieces by Catholic theologians replying to Ivereigh. It will be interesting to see whether any of them dissent and actually argue in favour of same-sex marriage. I've told often of late that many Catholic leaders and theologians dissent from the views of the Vatican and from traditional teachings on sexual morality. I haven't seen much evidence for this (though there is plenty of evidence that ordinary Catholics dissent from Vatican teachings in great numbers). Perhaps we'll see some surprises with this new batch of articles. Here's hoping!
