From the LDS web page:
Question:
What is the Church's position on abortion?
Answer:
In 1973, the First Presidency of The Church of Jesus Christ of Latter-day Saints released the following statement regarding abortion, which is still applicable today: "The Church opposes abortion and counsels its members not to submit to or perform an abortion except in the rare cases where, in the opinion of competent medical counsel, the life or good health of the mother is seriously endangered or where the pregnancy was caused by rape and produces serious emotional trauma in the mother. Even then it should be done only after counseling with the local presiding priesthood authority and after receiving divine confirmation through prayer."
Thanks. That pretty much corroborates what I said. Pretty weak.
