Faith, hope and charity
To those commentators who are calling for her to be disbarred from holding this office, I would say this: is this truly the path we wish to go down? Surely, the state is secular and must remain blind to an individual's personal beliefs and religion when selecting her representatives. For so long as a minister is competent to perform their role, it is not up to the government to consider how they might feel about doing so. To discriminate against public servants on the grounds of their privately held views sets a dangerous precedent, as demonstrated by the European Parliament's decision to oust Rocco Buttiglione for having the moral courage to publicly declare his disapproval of homosexuality based upon his faith. If we continued along this route, then surely no Catholic could work in any hospital in which abortions were carried out, no Muslim could work in the Treasury (which derives significant income from sources prohibited under Shari'ah law, such as the sale of alcohol), no animal rights sympathiser could work for the NHS (which routinely procures and prescribes drugs which have been tested on animals), and ... you get the point.
To Ruth Kelly, on the other hand, I would say that if you really believe in the truth and integrity of the Catholic faith and in its teachings, (including the doctrine that practising homosexuality is a sin), how can you, in all conscience, defy your God and your Church in order to further your political career?
Sadly, the conclusion I am forced to draw is that Ruth Kelly has at this crucial moral moment chosen to ignore her faith in the hope that her electorate and her God will have the charity to ignore such blatant hypocrisy.
