Carl Trueman on Evacuating the Definition of Marriage
Gay marriage does not simply involve a minor expansion of the traditional concept. There was a time when gay writers such as Andrew Sullivan argued that allowing same-sex marriages would simply permit gay people to be part of a conservative institution. It is now clear that gay marriage did not merely expand the set of those considered to be married, but fundamentally evacuated marriage of meaning — or, more accurately, exposed the fact that it had already been fundamentally evacuated of meaning by the ready acceptance of no-fault divorce. It is no longer a unique relationship whose stability is important for its normative ends, but little more than a sentimental bond that only has to last for as long as it meets the emotional needs of the parties involved.
