What is the teaching of the Catholic Church on abortion? You’ll find it in the Catechism of the Catholic Church. We doubt that Gov. Kulongoski owns a Catechism.
Formal cooperation in an abortion constitutes a grave offense. The Church attaches a canonical penalty of excommunication to this crime against human life.  The Church does not thereby intend to restrict the scope of mercy. Rather, she makes clear the gravity of the crime committed, the irreparable harm done to the innocent who is put to death, as well as to the parents and the whole of society.
The inalienable right to life of every innocent human individual is a constitutive element of a civil society and its legislation:
“The inalienable rights of the person must be recognized and respected by civil society and the political authority. These human rights depend neither on single individuals nor on parents; nor do they represent a concession made by society and the state; they belong to human nature and are inherent in the person by virtue of the creative act from which the person took his origin. Among such fundamental rights one should mention in this regard every human being’s right to life and physical integrity from the moment of conception until death.”
