I ran across this article on the Catholic News Agency.
Life and Family: The “Morning-After Pill”, Rape Victims and Ethical and Religious Directives for Catholic Health Care Services :: Catholic News Agency (CNA)
It is worth a read. It is a fairly good description of the state of thinking among Catholic theologians. I do not completely agree with the conclusions of the author, however, and will comment upon this later. His position is definitely helpful but I have some questions.
