Tom Wright on Episcopals and gay question

Tom Wright, Bishop of Durham and one of the foremost Biblical scholars, wrote the following piece on the Episcopal Church's decision to move forward in recognizing gay unions, despite warnings from the Anglican Communion not to do so: http://www.timesonline.co.uk/tol/comment/columnists/guest_contributors/article6710640.ece. What do you think of his stance on sexuality?

Wright writes in his piece:

"The appeal to justice as a way of cutting the ethical knot in favour of including active homosexuals in Christian ministry simply begs the question. Nobody has a right to be ordained: it is always a gift of sheer and unmerited grace. The appeal also seriously misrepresents the notion of justice itself, not just in the Christian tradition of Augustine, Aquinas and others, but in the wider philosophical discussion from Aristotle to John Rawls. Justice never means “treating everybody the same way”, but “treating people appropriately”, which involves making distinctions between different people and situations. Justice has never meant “the right to give active expression to any and every sexual desire”."

What do you think of justice as "treating people appropriately" rather than "treating everybody the same?"
