I thought there was something wrong in the articles I read about the Anglican Church apparently approving the killing of severely disabled infants. It sounded suspiciously like a typical media twisting of loosely related events (after all, shock sells). The British Royal College of Obstetricians and Gynecology is promoting the active killing of severely disabled infants. The Anglican Church, as far as I am able to discern, was only reconfirming that severely disabled infants don't need to be kept alive through extraordinary medical means at all costs. Amy Welborn has details here.
It does look like some additional clarity on the part of the Anglican Church on such an important matter (and where others are pushing a completely different and even abhorent concept) might very well have helped, however the newspaper that made this report has had a history of seriously misconstruing church related issues in the past.
