The author is Vincentian Fr. Richard Benson of St. John's Seminary in Camarillo. Among his many points is this:
"Finally, it needs to be mentioned that there is growing awareness that certain 'contraceptives' like the birth control pill may actually have an abortive effect. It is becoming clear that hormonal methods not only suppress ovulation to prevent fertilization, and so are definitely contraceptive, but that also, at times, the contraceptive action fails and fertilization can and does take place. When this happens, these same contraceptives then work to make it impossible for the new life to implant in the uterus and thus cause an early abortion.
"This effect is much more likely in the case of hormone regimens designed to be ingested after intercourse like the 'morning-after' pill. When such methods are used after fertilization has already taken place, their only possible effect is abortive."
Pro-lifers have been pointing out the Pill's abortifacient effect since the 1970's. And even a pro-abortion lawyer acknowledged it in 1989, as the following attests:
"The New York Times of Thursday, April 27, 1989 carried a transcript of the oral arguments in the Supreme Court case of Webster v. Reproductive Health Services. On pB13 the following dialogue between Frank Susman, lawyer for the Missouri abortion clinics and Justice Scalia appears: 'Mr. Susman: 'The most common forms of what we most generally in common parlance call contraception today, IUD’s, low-dose birth control pills, which are the safest type of birth control pills available, act as abortifacients. They are correctly labeled as both.'" http://www.aaplog.org/collition.htm

In fact, an L.A. archdiocesan 40th anniversary celebration of Humanae Vitae next year, which ole Q has proposed, could line up Dr. Janet Smith as a speaker, along with Fr. Benson and others.
