Below are four excerpts from the CCC. DM has offered some excellent biblical truth and apologetic reasoning/logic–and prayerful support. I would only add (re:
the issue of when life begins)…that**
science (doctors / AMA–American Medical Association/many others) have unequivocally stated that human life begins at conception:
**(below is from the pro-life site --Abort73.com)
abort73.com/HTML/I-A-1-medical.html
**"**The official Senate report reached this conclusion:
Physicians, biologists, and other scientists agree that ***conception ***marks the ***beginning of the life of a human being *
- a being that is alive and is a member of the human species. There is overwhelming agreement on this point in countless medical, biological, and scientific writings.
This, of course, should come as no surprise since the American Medical Association (AMA) declared as far back as 1857 (referenced in the Roe. v. Wade opinion) that "the independent and actual existence of the child before birth, as a living being” is a matter of objective science. They deplored the “popular ignorance…that the foetus is not alive till after the period of quickening.” **
Doctors knew it during the 1800’s and doctors know it today. Human life begins at conception.
I believe that the Church has never doctrinally/definitively said that the spirit-soul is infused at conception…but the below CCC excerpts (along with DM’s scripture references) surely lead to the most likely correct answer…at conception.
363 In Sacred Scripture the term “soul” often refers to human *life *or the entire human
person.230 But “soul” also refers to the innermost aspect of man, that which is of greatest value in him,231 that by which he is most especially in God’s image: “soul” signifies the
spiritual principle in man.
1703 Endowed with “a spiritual and immortal” soul,5 the human person is "the only creature on earth that God has willed for its own sake."6 From his conception, he is destined for eternal beatitude.
**1711 **Endowed with a spiritual soul, with intellect and with free will, ***the human person is from his very conception ordered to God and destined for eternal beatitude. ***He pursues his perfection in “seeking and loving what is true and good” (*GS *15 § 2).
1718 The Beatitudes respond to the natural desire for happiness. This desire is of divine origin: God has placed it in the human heart in order to draw man to the One who alone can fulfill it: We all want to live happily; in the whole human race there is no one who does not assent to this proposition, even before it is fully articulated. How is it, then, that I seek you, Lord? Since in seeking you, my God, I seek a happy life, let me seek you so that my soul may live, **for my body draws life from my soul **and
my soul draws life from you.
**God alone satisfies. **
In any case…the
Church has
always taught from the times of the Apostles that
abortion is grave evil/sin…irregardless of science and when life begins or the spirit-soul is infused (note: both St. Augustine and St.Thomas Aquinas taught that abortion is always evil even though scientifically they were in the dark about life at conception…no matter what lies/errors Senator (now VP) Joe Biden or Speaker Nancy Pelosi say about what these two great Saints taught) :
Didache
The Lord’s Teaching Through the Twelve Apostles to the Nations. (written by apostles between the years 50 - 120 AD)
(Chapter 2. The Second Commandment: Grave Sin Forbidden. And the second commandment of the Teaching; You shall not commit murder, you shall not commit adultery, you shall not commit pederasty, you shall not commit fornication, you shall not steal, you shall not practice magic, you shall not practice witchcraft, you shall not murder a child by abortion nor kill that which is born.
Hope some of this helps.
