To your list of insightful Lutheran bloggers, you may add the Rev. Robert Baker. His blog, Bioethike, is as thought-provoking as it is well written.
Today, he posted this, along with the following video.
"While Dr. Bernard Nathanson’s confession about abortion (Dr. Nathanson was a founding member of what is know today as NARAL Pro-choice America) is not new, I believe the following video is powerful and effective. Dr. Nathanson converted to Catholicism in 1996 and I rejoice that he has found forgiveness in Absolution and the Sacrament of the Altar. May God bless Dr. Nathanson."
