There is no doubt about the fundamental value that we place upon marriage and its role at the heart of our society. Marriage embodies the principles of love, loyalty and commitment - all vital components of a strong society. And it is those principles that we are championing through the Equal Marriage Bill which continues its journey through Parliament tonight.
Gay rights are human rights, and human rights are not the province of Christianity or any other religion for that matter. Mr Carey is suggesting that the right to marry is somehow the province of religion, not the state. That, by definition, is 'relativism,' which the former archbishop seems unwilling to recognise, despite rushing to condemn it.
Were one to say "there are some black people whose intelligence I find stunning and am challenged by it," we would quickly denounce it as racist - and rightly so... Needless to repeat then his opposition to equal marriage, which alone, according to Peter Tatchell, is enough to establish Mr Welby's prejudice against gay people.
For the last nine years, many transgender people in the UK have faced a terrible dilemma. In 2004 the Gender Recognition Act was passed. This piece of legislation allowed transgender people rights in law to be recognised as their identified gender. This is more important than you might initially think.
Does the government think that all same sex partners' sexual morals are so louche that the idea of a monogamous relationship is alien and therefore adultery is not needed to support a divorce petition? Does the government think same sex couples' sexual appetites are so voracious that no same-sex marriage could possibly remain unconsummated?
This was a fact celebrated at Sunday's March for Marriage in Dublin where 6,000 people snaked through the streets from City Hall to St. Stephen's Green. The infectious snap of samba drums ricocheted up and down Kildare Street where protestors chanted: "What do we want? Equal rights! When do we want it? Now!" as they stopped outside the gates of Leinster House, the home of the DĂ¡il and Seanad (the upper and lower houses of parliament).
Later this week, Dublin City shall witness what looks set to be a phenomenal turnout for the LGBT Noise 'March for Marriage' protest.
According to opponents of gay marriage, it is a measure that only attracts support amongst the "metropolitan elite" - according to their analysis once you step outside of Hampstead or Soho , support for equal marriage simply withers away. Former Defence Secretary, Dr Liam Fox was the latest political figure to use this argument, suggested that the Government's proposals for gay marriage represented "social engineering" on the part of a "metropolitan elite." The only trouble is that, in the case of gay marriage, it simply isn't true.
