If you don't read another article about Terri Schiavo, please read this one -- Necessary decisions: Taking sides for Schiavo from The Christian Century. It explains clearly and eloquently how Christians can reason Biblically and yet disagree on the Schiavo case.
This article brings a much-needed perspective to the debate. A must read!! I can't emphasize that enough.
Also well worth reading, from the same magazine, is Schiavo drama feeds political frenzy.
