Again, the Catholic Church’s position on abortion has clearly developed/changed.
Again to those who misrepresent what Pres. Kimble said, like done in the Catholic Answers track, have created a change were none exited. Here is the complete Kimble quote.
The Teachings of Spencer W. Kimball, p.188-189:
Abortion is a serious sin. There is such a close relationship between the taking of a life and the taking of an embryonic child, between murder and abortion, that we would hope that mortal men would not presume to take the frightening responsibility. … Abortion is a calamity, and if the gospel came into play in the lives of men and women, an abortion would be rare indeed, if at all. If men and women are living the gospel of Jesus Christ, which is the cure for all ills, there would be no illegitimate conceptions, and this would erase from the abortion docket the great majority of the abortions. However, weak, selfish women now require abortions, even in many cases where there is not the illegitimate conception. Abortion calls for Church discipline. Much is being said in the press and in the pulpit concerning abortion. This Church of Jesus Christ opposes abortion and counsels all members not to submit to nor participate in any abortion, in any way, for convenience or to hide sins. Abortion must be considered one of the most revolting and sinful practices in this day, when we are witnessing a frightening evidence of permissiveness leading to sexual immorality. We take the solemn view that any tampering with the fountains of life is serious, morally, mentally, psychologically, physically. Members of the Church guilty of being parties to the sin of abortion must be subjected to the disciplinary action of the councils of the Church, as circumstances warrant. We remember the reiteration of the Ten Commandments given by the Lord in our own time, when he said, “Thou shalt not steal; neither commit adultery, nor kill, nor do anything like unto it.” (D&C 59:6.) We see some similarities. Abortion is permissible only in exceptional situations. Abortion, the taking of life, is one of the most grievous of sins. We have repeatedly affirmed the position of the Church in unalterably opposing all abortions, except in … rare instances … and when competent medical counsel indicates that a mother’s health would otherwise be seriously jeopardized. Those encouraging abortion share guilt. It is almost inconceivable that an abortion would ever be committed to save face or embarrassment, to save trouble or inconvenience, or to escape responsibility. How could one submit to such an operation or be party in any way by financing or encouraging? Certainly the women who yield to this ugly sin, … and those who assist them, should remember that retribution is sure. Easy abortion is related to licentiousness. When abortions are permitted and encouraged even as a means of population limitation, it is the voice of the underworld encouraging sex without license or controls.”””
If one reads these two documents in their entirety one will find that the first in history (President Kimball) was intentionally or grossly incompetently misquoted to create an issue of inconsistency where there was none. In two place President Kimble talks of “exceptional circumstances” and “rare instance.” In the “rare instances” he specifically mentions term 2 in the handbook.
I am not aware of the complete 1988 Gospel Principles teaching, but Kimble predates this by 6 years.
The LDS position is seemingly more consistent than the changing Catholic position.
