Conception, Fertilization or implantation

Did you know that nowadays when we say “conception” people may be thinking two different things? Thanks to modern medical propaganda that furthers the culture of death, there is an additional (and so-called) “definition” for conception. While most Catholics should know that conception occurs with fertilization, the new “definition” from the prevalent medical community says that conception happens at implantation.
Why did they change the definition of conception? As Dr. Brian Clowes points out in The Facts of Life, “In 1963, the United States Department of Health, Education and Welfare (HEW) defined abortion as "all the measures which impair the viability of the zygote at any time between the instant of fertilization and the completion of labor." Until the mid-1960s, scientists universally acknowledged that conception occurred at the moment of fertilization of the ovum by the spermatozoa, somewhere in the fallopian tube.
But pro-abortionists and population controllers already had their sights set on a shift from contraceptive to abortifacient methods of artificial birth prevention - - and such abortifacient research was already ongoing in Japan and several European countries. To accomplish their desired change, the death promoters needed to pervert the definition of "conception" from fertilization [union of spermatozoa and ovum] to implantation. Under their fabricated new “definition,” if a device or drug — such as an IUD or Depo-Provera — prevents implantation, then no abortion takes place! For them, abortion would only occur if a device or chemical killed a pre-born child who had already implanted in the endometrium (lining) of the uterus.
The pro-abortionists' continuing agitation for a change in terminology was finally successful in 1965, when the American College of Obstetrics and Gynecology (ACOG) published its first Terminology Bulletin, stating that "conception is the implantation of a fertilized ovum." This semantic subterfuge resulted in the Bulletin inventing two additionally misleading terms for early abortion: "Post-conceptive contraception" and "post-conceptive fertility control."”
Why is it important to know these facts? Well, when we speak to people (who may even be well meaning and sincere) and they say such things as “the pill and Depo-Provera do not cause abortions” it may just be that they have accepted the altered definitions. But clearly, just because I start using the term “conception” to mean something other than fertilization, does not change the reality. If they decide to move “conception” to the time when the baby now resides in our environment instead of that inner environment of the womb, this obviously would not change the fact that a new human being has been created at the time of fertilization.
When I would preach about this at Mass, I have had many good responses from the people because they love to hear how the “other side” works. Additionally, many people, if given the chance, appreciate truth and are eager to respond. Hopefully we can use this knowledge to help train others how to speak pro-life.
